Description

A device that automatically measures and monitors taste and odor-causing substances in water (raw water, purified water, and effluent)

[0001] The present invention relates to a device and method for automatically measuring and monitoring taste and odor-causing substances in water (raw water, purified water, and effluent water).

[0002] Taste and odor-causing substances related to water supply can be broadly divided into natural and artificial ones, but naturally occurring substances caused by biological processes are more common.

[0003] Naturally occurring taste and odor substances are mostly found to be caused by algae. Representative taste and odor substances derived from algae include 2-MIB and geosmin.

[0004] 2-MIB and Geosmin can be treated to below the olfactory detection concentration before they are introduced into the distribution water network by rapid water treatment at water purification plants (injecting ozone, hydrogen peroxide, powdered activated carbon, etc.) to avoid consumer complaints. However, at present, water purification plants extract a sample, then inject the sample into a gas chromatograph with a separation column, and analyze it with a mass spectrometer after thermal desorption. Since the entire analysis process takes a long time due to manpower, it is difficult to respond immediately, and there are limitations in responding to water purification because it is impossible to respond immediately when taste and odor substances occur.

[0005] Accordingly, attempts are being made to build a system that automatically analyzes odor-causing substances [2-MIB, Geosmin], but the entire process involves collecting and analyzing samples manually, which takes a lot of measurement time and is therefore impractical.

[0006] Therefore, there is a need to develop an economical and practical system that can measure these substances in real time.

[0013] The purpose of the present invention is to provide a device and method for automatically measuring and monitoring taste and odor-causing substances in water (raw water, purified water, and effluent) in a new way.

[0014] According to one embodiment of the present invention for solving the above problem, a device for automatically measuring and monitoring taste and odor-inducing substances in water includes: a vaporization unit that introduces raw water, purified water, or waste water, atomizes the raw water using an ultrasonic vibrator, and then generates an aerosol-type sample; an MS / MS mass spectrometry unit that applies a chemical ionization method using plasma and a quadrupole mass spectrometry (MS / MS) to the aerosol-type sample generated in the vaporization unit to measure the mass values ​​of taste and odor-inducing substances, 2-MIB and Geosmin; and a digitization unit that digitizes a specific ion mass among the fragment ion masses of 2-MIB and Geosmin compared to the sample mass measured by the MS / MS mass spectrometry unit.

[0015] In one embodiment, the vaporization unit is characterized by including a tank having an inlet / outlet pipe formed to introduce and discharge water (raw water, purified water, waste water); an ultrasonic vibration unit that atomizes water introduced into the tank using an ultrasonic vibrator; and a spray chamber that generates the atomized water into an aerosol-type sample.

[0016] In one embodiment, the vaporizer and the MS / MS mass spectrometry unit are characterized in that they are connected by a Teflon tube.

[0017] In one embodiment, the Teflon tube is characterized by having a heating wire for maintaining the surface temperature at a preset temperature for stabilization with the ambient temperature.

[0018] In one embodiment, the MS / MS mass spectrometer continuously draws moisture in the atmosphere into the ion source and exposes it to plasma, thereby generating plasma-type H3O generated by corona discharge. + After generating ions, the method is characterized by inducing an ion reaction in an aerosol-type sample introduced from the vaporizer to first calculate the ion mass of the sample substances, 2-MIB and Geosmin.

[0019] In one embodiment, the MS / MS mass spectrometry unit is characterized in that it secondarily calculates a specific ion mass among the fragment ion masses of 2-MIB and Geosmin by filtering out other volatile organic compounds in the sample material through a collision cell reaction using air.

[0020] According to one embodiment of the present invention for solving the above problem, a method for automatically measuring and monitoring taste and odor-inducing substances in water (raw water, purified water, and waste water) includes: a sample generation step of introducing raw water, purified water, or waste water into a vaporization unit, atomizing the raw water using an ultrasonic vibrator, and then generating an aerosol-type sample; a step of applying a chemical ionization method using plasma and quadrupole mass spectrometry (MS / MS) to the aerosol-type sample generated in the vaporization unit in an MS / MS mass spectrometry unit to measure and monitor the mass values ​​of taste and odor-inducing substances, 2-MIB and Geosmin; and a step of digitizing a specific ion mass among the fragment ion masses of 2-MIB and Geosmin with respect to the sample mass measured in the MS / MS mass spectrometry unit in a digitization unit.

[0021] In one embodiment, the sample measurement and monitoring step is performed by continuously sucking moisture in the atmosphere into the ion source in the MS / MS mass spectrometry unit and exposing it to plasma, thereby generating H3O in the form of plasma generated by corona discharge. + After generating ions, the method comprises a step of first calculating the ion mass of the sample material, 2-MIB and Geosmin, by inducing an ion reaction in the aerosol-type sample introduced from the vaporizer; and a step of second calculating a specific ion mass among the fragment ion masses of 2-MIB and Geosmin, which are obtained by filtering other volatile organic compounds from the sample material through a collision cell reaction using air.

[0022] According to one embodiment of the present invention, a device and method for automatically measuring and monitoring taste and odor-causing substances in water (raw water, purified water, effluent) are used, which, unlike conventional analysis methods, eliminates the need for a column or gas chromatograph device to separate the substances, thereby shortening the measurement time, and furthermore, real-time measurement of taste and odor-causing substances is possible during the algae growth period at high temperatures, thereby reducing costs through efficient injection of an appropriate amount of treatment chemicals (ozone, hydrogen peroxide, powdered activated carbon, etc.), thereby reducing the budget.

[0023] In addition, by transmitting data to the situation room in real time, it is possible to monitor the concentration of odor-causing substances in the water source in real time, which was difficult to monitor in real time due to the delay in monitoring the concentration changing in the existing analysis system. In particular, since measurements can be made even at night and on weekends when no one is working, it is possible to quickly determine whether taste- and odor-causing substances are occurring in the water (raw water, purified water, effluent). Accordingly, it is possible to take rapid response measures such as strengthening water purification treatment at water purification plants, which can minimize damage such as deterioration of tap water quality caused by taste- and odor-causing substances.

[0036] Hereinafter, a device and method for automatically measuring and monitoring taste and odor-causing substances in water (raw water, purified water, effluent) according to one embodiment of the present invention will be described in more detail based on the attached drawings.

[0037] FIG. 1 is a characteristic table of Geosmin and 2-MIB, FIG. 2 is an exemplary diagram of a device for automatically measuring and monitoring taste and odor-causing substances in water (raw water, purified water, and effluent) according to an embodiment of the present invention, FIG. 3 is a diagram showing changes in the arrangement of ultrasonic vibrator components depending on whether or not current is applied, FIG. 4 is a detailed diagram of the MS / MS mass spectrometry unit shown in FIG. 1, FIG. 5 is an exemplary diagram for explaining the stable region of a quadrupole, and FIG. 6 is an exemplary diagram for explaining a particle filtering method using a scan line.

[0038] Meanwhile, before explaining the present invention, the present invention is a device and method for measuring and monitoring the ion mass of 2-MIB and Geosmin, which are taste and odor-causing substances in water (raw water, purified water, effluent), and unlike the existing analysis method (Heasspace-SPME-mass spectrometry), it can shorten the measurement time without the need for a column or gas chromatograph device to separate the substances, and it can measure taste and odor-causing substances in real time during the high-temperature algae generation period, and it can reduce costs by efficiently adding an appropriate amount of treatment chemicals (ozone, hydrogen peroxide, powdered activated carbon, etc.), so it can be a new concept device and method that can reduce the budget.

[0039] As illustrated in FIG. 1, a device (100) for automatically measuring and monitoring taste and odor-causing substances in water (raw water, purified water, discharged water) according to one embodiment of the present invention includes a vaporization unit (200), an MS / MS mass analysis unit (300), and a numerical unit (400).

[0040] The above vaporization unit (200) may be configured to introduce raw water, purified water, or waste water, atomize it using an ultrasonic vibrator, and then generate a sample in the form of an aerosol.

[0041] More specifically, the vaporization unit (200) includes a water tank unit (210), an ultrasonic vibration unit (220), and a spray chamber (230).

[0042] The water tank (210) is configured to introduce and discharge water (raw water, purified water, effluent water), and may be a glass tube with an inlet / outlet pipe formed therein.

[0043] The ultrasonic vibration unit (220) may be configured to atomize the raw water introduced into the water tank unit (210) through an ultrasonic vibrator.

[0044] The spray chamber (230) may be configured to capture atomized water (raw water, purified water, discharged water) as an aerosol-type sample and then spray it through a Teflon tube (10) described later.

[0045] The aerosol-type sample captured in the above spray chamber (230) is transferred to the MS / MS mass spectrometry unit (300) described later along the Teflon tube (10).

[0046] The above Teflon tube (10) may be configured with a heating wire to maintain the surface temperature at a preset temperature in order to prevent the moving aerosol-type sample from liquefying due to the atmospheric temperature difference.

[0047] Next, the MS / MS mass spectrometry unit (300) may be configured to measure the mass values ​​of taste and odor-inducing substances, 2-MIB and Geosmin, by applying a chemical ionization method using plasma and quadrupole mass spectrometry (MS / MS) to an aerosol-type sample generated from the vaporization unit (200).

[0048] The above MS / MS mass spectrometry unit (300) continuously sucks moisture in the atmosphere into the ion source and exposes it to plasma, thereby generating plasma-type H3O generated by corona discharge. + After generating ions, the configuration may be configured to induce an ion reaction in an aerosol-type sample introduced from the vaporizer to first calculate the ion mass of the sample materials, 2-MIB and Geosmin.

[0049] The above MS / MS mass spectrometry unit (300) may be configured to secondarily calculate a specific ion mass among the fragment ion masses of 2-MIB and Geosmin by filtering out other organic compounds in the sample material through a collision cell reaction using air.

[0050] The above MS / MS mass spectrometry unit (300) may be configured to detect ionized substances according to the mass to charge ratio by connecting two MS (Mass Spectrometry) units in parallel.

[0051] More specifically, the MS / MS mass spectrometry unit (300) includes an ionization unit (310), a quadrupole (320), and a mass detection unit (330).

[0052] The above ionization unit (310) continuously sucks moisture in the atmosphere into the ion source and exposes it to plasma, thereby generating H3O in the form of plasma by corona discharge. + It may be a configuration that generates ions.

[0053] M + H3O + → MH + + H2O

[0054] MH + → (M-OH) + + H2O

[0055] Additionally, it may be a configuration that generates an ionic reaction of an aerosol-type sample captured in the vaporizer (200).

[0056] C 11 H 20 O(168) + H + (1) - H2O(18) → C 11 H 19 + (151)

[0057] C 12 H 22 O(182) + H + (1) - H2O(18) → C 12 H 21+ (165)

[0058] The above ionization unit (310) can be driven by any one of a filament-based thermal electron method, a laser method, and an inductively coupled plasma method, depending on the driving method. In the present invention, the inductively coupled plasma method is described.

[0059] Next, the quadrupole (320) may be configured to filter particles to be measured by applying direct current and alternating current to two pairs of conducting rods.

[0060] When direct current or alternating current is applied to the quadrupole, an electric field is determined within the quadrupole, and the incident ions are accelerated and move by this electric field.

[0061] The principle is that particles that move stably and reach the current meter are measured, while particles that move unstably and collide with the quadrupole are not measured, allowing us to measure only the particles we want.

[0062] The ionized sample in the ionization section (310) enters the quadrupole, and at this time, only particles of a specific mass that can pass under the direct current or alternating current voltage applied to the quadrupole pass through the quadrupole, and particles of other mass collide with the quadrupole and are annihilated.

[0063] For reference, for an ideal quadrupole filter, the hyperbolic electrodes should be arranged in a quadrupole shape, and the Laplace equation for the potential inside the quadrupole is known as follows.

[0064] [Formula 1]

[0065]

[0066] Here, α, β, and γ are values ​​according to the positions of x, y, and z, respectively. The voltages applied to the two electrodes located on the x-axis and the two electrodes located on the y-axis are as shown in Equations 2 and 3 below.

[0067] [Formula 2]

[0068]

[0069] [Formula 3]

[0070]

[0071] Here, U represents the DC voltage and V represents the RF voltage. To obtain the equation of motion of ions passing through the quadrupole filter, the potential inside the quadrupole filter must first be obtained. The potential inside the quadrupole filter must satisfy the Laplace equation and does not change along the z-axis. Therefore, the potential is as follows: Equation 4

[0072] [Formula 4]

[0073]

[0074] Here, r0 means the distance from the origin to one cylinder of the quadrupole, refers to the direct current or alternating current voltage applied to the quadrupole. If the above potential is entered into the Lorentz equation, the following equation of motion of the ion can be derived as in Equation 5.

[0075] [Formula 5]

[0076]

[0077] Here, ξ = ωt, ω = 2πf. au and qu are called stability factors, and their values ​​are as shown in Equations 6 and 7, respectively.

[0078] [Formula 6]

[0079]

[0080] [Formula 7]

[0081]

[0082] Z represents the charge of the ion, and e represents the elementary charge. The above equation of motion is called Mathieu's equation.

[0083] By using Mathieu's equation, we can obtain a triangular region as in Figure 4 by drawing only the voltage conditions under which a particle passes through the quadrupole located on the x and y axes without colliding with it.

[0084] This is called the stability region for the particle in question, and since this stability region is the transmission characteristic when a particle under specific conditions enters the quadrupole filter, it can be said to be the passage characteristic when the particle in question enters the quadrupole filter.

[0085] Based on this stable region, the voltage conditions on the left are conditions that hit the rod located on the y-axis, and the conditions on the right are conditions that hit the rod located on the x-axis.

[0086] Also, even if it is a condition that hits the x-axis or y-axis rod, the condition that is closer to the stable region has a characteristic that the time it takes to hit the quadrupole is relatively later than the condition that is located farther away.

[0087] Meanwhile, the direct current and alternating current power applied to the quadrupole is usually expressed as follows.

[0088] U = 1.167 V

[0089] Here, U represents direct current voltage and V represents alternating current voltage.

[0090] The voltage application method in which AC voltage and DC voltage are expressed in the form of a linear function is called a scan line.

[0091] The method of filtering particles using scan lines can be expressed as shown in Fig. 6.

[0092] In the region where the scan line and the stable region of the incident particle meet, the particle passes through the quadrupole, and is filtered out where they do not meet.

[0093] Therefore, when different particles are incident, since the size of each stable region is different, by applying voltage along the scan line, it is possible to determine whether each particle is transmitted or not according to the applied AC voltage, as shown on the right side of Fig. 6.

[0094] The sample filtered in this way hits the mass detector (330) to generate a current, and by measuring this current, the type of gas sample and the mass-to-charge ratio (m / z) can be determined.

[0095] C 11 H 20 O(168) + H + (1) - H2O(18) → C 11 H 19 + (151)

[0096] 2-MIB → 151 m / z

[0097] C 12 H 22 O(182) + H + (1) - H2O(18) → C 12 H 21 + (165)

[0098] Geosmin → 165 m / z

[0099] The above mass detection unit (330) usually uses a Faraday cup or an electron amplifier.

[0100] Meanwhile, since the MS / MS mass spectrometry unit (300) may contain organic compounds other than the sample material among the samples to be measured, it performs a collision cell reaction once more to measure the final mass value as shown below.

[0101] 2-MIB → 151 m / z → Collision reaction using air → 95 m / z

[0102] Geosmin → 165 m / z → Collision reaction using air → 112 m / z

[0103] The above numerical unit (400) may be configured to numerically quantify a specific ion mass among the fragment ion masses of 2-MIB and Geosmin compared to the sample mass measured by the MS / MS mass analysis unit (300).

[0104] FIG. 7 is a flowchart illustrating a method for automatically measuring and monitoring taste and odor-causing substances in water (raw water, purified water, and effluent) according to one embodiment of the present invention.

[0105] Referring to FIG. 7, a method (S700) for automatically measuring and monitoring taste and odor-causing substances in water (raw water, purified water, effluent) according to one embodiment of the present invention includes a sample generation step (S710), a sample measurement and monitoring step (S720), and a digitization step (S730).

[0106] The above sample generation step (S710) may be a step of introducing raw water, purified water, or discharged water into a vaporization unit, atomizing it using an ultrasonic vibrator, and then generating a sample in the form of an aerosol.

[0107] The above sample measurement and monitoring step (S720) may be a step of applying chemical ionization using plasma and quadrupole mass spectrometry (MS / MS) to an aerosol-type sample generated in a vaporization unit in an MS / MS mass spectrometry unit to measure the mass values ​​of taste and odor-inducing substances, 2-MIB and Geosmin.

[0108] The above sample measurement and monitoring step (S720) continuously sucks moisture in the atmosphere into the ion source in the MS / MS mass spectrometry unit and exposes it to plasma, thereby generating H3O in the form of plasma generated by corona discharge. +After generating ions (S721), the process includes first calculating the ion mass of the sample material, 2-MIB and Geosmin, by inducing an ion reaction in the aerosol-type sample introduced from the vaporizer (S722), and second calculating a specific ion mass among the fragment ion masses of 2-MIB and Geosmin by filtering out other organic compounds in the sample material through a collision cell reaction using air (S723).

[0109] Next, the digitization step (S730) may be a step (S730) of digitizing a specific ion mass among the fragment ion masses of 2-MIB and Geosmin compared to the sample mass measured in the MS / MS mass spectrometry unit in the digitization unit.

[0110] Therefore, by using the device and method for automatically measuring and monitoring taste and odor-causing substances in water (raw water, purified water, effluent) according to one embodiment of the present invention, unlike the existing analysis method, a column or gas chromatograph device for separating the substances is not required, thereby shortening the measurement time. In addition, since real-time measurement of taste and odor-causing substances is possible during the algae growth period at high temperatures, there is an advantage in that the budget can be reduced by efficiently adding an appropriate amount of treatment chemicals (ozone, hydrogen peroxide, powdered activated carbon, etc.) to reduce costs.

[0111] In addition, by transmitting data to the situation room in real time, it is possible to monitor the concentration of odor-causing substances in the water source in real time, which was difficult to monitor in real time with the existing analysis system, and in particular, measurement is possible even at night and on weekends when no one is working, so it is possible to quickly determine whether taste and odor-causing substances occur in the water (raw water, purified water, effluent), and accordingly, rapid response measures such as strengthening water treatment at water purification plants can be taken, which can minimize damage such as deterioration of tap water quality caused by taste and odor substances.

Additionally, the processing device can access, store, manipulate, process, and generate data in response to the execution of the software.
