[0003] DISCLOSURE AREA

[0004] This disclosure falls within the technical area of ​​miniaturized systems, in a laboratory and / or experimental context, defining a water treatment plant. The plant in this disclosure and its components are miniaturized when compared to large-scale plants, such as water treatment plants within large infrastructures.

[0005] STATE OF THE TECHNIQUE

[0006] Solutions that seek to simulate the operation of water treatment plants for educational purposes are known in the state of the art.

[0007] These solutions simulate the operation of plants, including elements that, for example, are intended to represent contaminants, but which are not contaminants, consisting only of fictitious elements with which they seek to demonstrate how treatment plants work in general in a learning context.

[0008] These systems are nonfunctional and do not effectively treat water, at least not beyond removing these fictitious elements from the water or otherwise demonstrating how a water treatment plant would operate. These plants do not allow for the development of laboratory and research facilities.

[0009] Therefore, they do not require their components to function effectively to treat water in general.

[0010] The miniaturized plant of this solution allows for the efficient treatment, testing, and control of new contaminated water treatment models in an innovative way, in an environment of scientific development, research, and learning. PRESS RELEASE SUMMARY

[0040] DESCRIPTION OF FIGURES

[0041] Figure 1 - Schematic representation of a station according to the present disclosure. The station comprises a first reservoir (B101), whose outlet is connected to a level sensor (B120), a first valve (V102) and a fourth valve (V101). The fourth valve (V101) allows the flow of water contained in the first reservoir (B101) to a first drainage outlet (X101). Demineralized water can be added to the first reservoir as a solid and neutral base for the experiments to be performed. The first valve (V102) allows the demineralized water in the first reservoir to leave the first reservoir (B101) through its outlet, in the quantity and depending on the level sensor (B120), and this water can be pumped by the first pump (P110) to the second reservoir (B102), controlled and quantified by means of a flow meter (B121).In the second reservoir (B102), when a contaminant, such as a synthetic one, is added, it is diluted using the agitation media (Mill), resulting in contaminated water in a homogeneous solution. A chemical reagent can then be added and dissolved using the agitation media (Mill). The aeration pump (P112) also promotes dissolution. Both are electronically controlled and promote the chemical process, optimizing the reaction between contaminant and reagent and the consequent formation of residues resulting from the reaction. A second valve (V104) can be opened to allow treated or pretreated water to flow to a station water outlet (X102). The station may include a fifth valve (V105), which controls the flow of pretreated water to the station water outlet (X102). The deposited residues can exit through the bottom of the second reservoir (B102) as the station waste outlet (B103) by opening a third valve (V103).An overflow control element (Overflow) is arranged inside the second reservoir (B102) and connected to a third water outlet (Overflow) in such a way that when water inside the second reservoir (B102) reaches a pre-defined volume, it enters the overflow control element and leaves through the third water outlet (Overflow). The deposited waste outlet is formed in a lower section of the second reservoir (B102). The treated or pre-treated water outlet is in a lateral section of the second reservoir (B102). DETAILED DESCRIPTION.

[0042] The station described herein defines a miniaturized, mobile, digital water treatment monitoring and control system. Monitoring and control can be performed in real time using augmented reality.

[0043] The plant allows the treatment of contaminated water by oxidation-reduction. As mentioned, the water may be demineralized water to which a contaminant is added, which may be a synthetic contaminant.

[0044] To this end, the station comprises at least two tanks suitable for containing liquids, a first tank (B101) with at least one water inlet and one water outlet and a second tank (B102) with at least one water inlet and one water outlet, the water outlet being formed in a side section of the second tank (B102).

[0045] The second reservoir (B102) further comprises a waste outlet, which is formed in its lower section and is suitable for removing deposited waste at least by gravitational action. The water outlet of the first reservoir (B101) is connected to the water inlet of the second reservoir (B102) and the water outlet of the second reservoir (B102) is connected to a water outlet of the station (X102).

[0046] This forms a circuit in which water is pumped from the first reservoir (B101) to the second reservoir (B102). The outlets from the second reservoir (B102) are a water outlet, for the removal of water treated for contaminants, which allows water to leave the station (X102), and a waste outlet, from which waste resulting from a reaction that occurs inside the second reservoir (B102) and which generates waste sedimentation is extracted.

[0047] The station comprises a first valve (V102) and a first pump (P110).

[0048] The first valve (V102) is controllable—for example, a solenoid valve—and allows water to flow from the first reservoir (B101). On the other hand, the first pump (P110) is also controllable, allowing water contained in the first reservoir (B101) to be pumped to the second reservoir (B102). When the first valve (V102) is opened, the action of the first pump (B101) enables this pumping, which occurs from the outlet of the first reservoir (B101) to the second reservoir (B102) via the water inlet of the second reservoir (B102). This configuration allows water to flow from the first reservoir (B101) to the second reservoir (B102).

[0049] The station further comprises a second valve (V104). The second valve (V104) is also controllable, and allows water to exit from the second reservoir (B102) through the second outlet and thus to the station water outlet (X102). The opening of the second valve (V104) can thus occur when the reaction of removing a contaminant from water has completed and a resulting product has sedimented.

[0050] Each of the reservoirs has a capacity between 4 and 50 I, optionally 4 and 15 I, optionally 6 and 9 I.

[0051] This allows the station to be operated so that it is fed with demineralized water from the first reservoir, providing a solid and consistent foundation for all experiments and research. The first reservoir (B101) and / or the second reservoir (B102) can be graduated.

[0052] This station allows, in the main tank - the second reservoir (B102) -, the placement of synthetic samples and the addition of chemical reagents, each via an independent decantation funnel connected to the second reservoir (B102) or directly into the second reservoir (B102), according to water and wastewater parameters, recreating real water treatment processes, namely in the reduction of contaminants containing iron, manganese and other ions that are present in the water, both in suspended and dissolved form.

[0053] The station also allows water turbidity to be read throughout the process using portable equipment collected through an auxiliary orifice.

[0054] The station provides visualization of the formation, growth, and settling of flocs resulting from the reaction, as well as the behavior of flocs influenced by the speed of the agitation media (Mill)—for example, an electromechanical agitator with Servo Drive—as a real learning process. The station includes a third, electronically controllable valve (V103) that allows the discharge of deposited residues from the lower section of the second reservoir—the bottom of the second reservoir—through the waste outlet (Sludge Drain) and to a station waste outlet (B103). The third valve (V103) can thus open after the second valve (V104) opens to discharge contaminant-treated water, after the contaminant removal reaction has completed and the resulting product has settled.

[0055] A first drain outlet (X101) is connected to the outlet of the first reservoir (B101), and a fourth controllable valve (V101), which may be electronically controllable, allows water to flow through the outlet of the first reservoir (B101) to the first drain outlet (X101).

[0056] The first valve (V102) can be opened allowing water to drain between the first reservoir (B101) and the second reservoir (B102) to the drain outlet (X101).

[0057] The station may comprise means for determining the volume of water contained within the first reservoir (B120). The station may be configured to stop the operation of the first pump (P110) when the value obtained by the means for determining the volume of water contained within the first reservoir (B101) is zero or close to zero. The station may be configured to maintain the operation of the first pump (P110) when the value obtained by the means for determining the volume of water contained within the first reservoir (B101) is greater than or equal to a predefined value.

[0058] The station may comprise a flowmeter (B121). The station may be configured to stop the operation of the first pump (P110) when the value obtained by the flowmeter is greater than or equal to a pre-defined value. The station may be configured to maintain the operation of the first pump (P110) when the value obtained by the flowmeter (B121) is less than or equal to a pre-defined value. As an example, the pre-defined value may correspond to a maximum volume, this maximum volume corresponding to a total volume of the second reservoir (B102) or to a pre-established volume for carrying out an experiment in the second reservoir (B102).In one embodiment, the second reservoir (B102) - which can be considered a main reservoir - downstream of the first reservoir (B101) - which can be considered a feed reservoir - is equipped with agitation means (Mill) which can consist of an electromechanical agitator with dynamic control by servomotor with blade angle adjustment.

[0059] By containing electronically controllable mechanical agitation means arranged within the second reservoir, these act as a facilitator of a chemical process taking place within the second reservoir (B102), for example, a process in which a contaminant and a reagent react by chemical oxidation, generating flocs that settle to the bottom of the reservoir under the action of gravity. This reaction and the consequent formation of the reaction product are optimized by the operation of the agitation means.

[0060] The agitation media (Mill) can be rotary, with their rotation speed being electronically controllable. The rotation can correspond to a fast agitation rotation between 100 and 250 rpm, a moderate agitation rotation between 30 and 99 rpm, and / or a slow agitation rotation between 10 and 29 rpm.

[0061] The agitation media (Mill) may also have blades inclined between 35 and 55° relative to the axis of rotation of the rotating media, this inclination promoting oxidation and precipitation of the resulting product. The inclination may also be electronically controllable.

[0062] In one embodiment, the station comprises an aeration pump (P112) arranged inside the second reservoir (B102) such that, when water is inside it, air comes into contact with the water. The aeration pump (P112) promotes oxidation by oxygenation of the water, and also prevents the growth of anaerobic bacteria, which need oxygen-poor environments to survive.

[0063] It may also comprise a pH meter (B123) arranged inside the second reservoir (B102) in such a way that, when water is present inside it, it is capable of measuring the pH of the water. The second reservoir (B102) is therefore equipped with an in-line measuring block for analyzing the preliminary characteristics of the water, such as pH and free chlorine, where the oxidation-reduction process followed by the decantation process occurs.

[0064] The station may additionally comprise an overflow control element and a second drainage outlet (Overflow). The second reservoir (B102) thus comprises a third water outlet. The overflow control element is arranged within the second reservoir (B102) and connected to this third water outlet, such that when water within the second reservoir (B102) reaches a pre-defined volume, it enters the overflow control element and flows out through the third water outlet to the second drainage outlet (Overflow). The overflow control element thus provides an additional measure to prevent the water entering the second reservoir (B102) from exceeding a pre-defined level corresponding to said pre-defined volume.

[0065] The station of the present disclosure may comprise one or more controllers comprising computational means configured to control elements such as valves, pumps, and / or agitation means. It may also obtain monitoring data obtained from said sensors.

[0066] The present disclosure may also comprise a system comprising the station of the present disclosure and a remote or local controller. The remote or local controller may be configured to allow access to a human-machine interface (HMI) that allows activating station control commands of the present disclosure, by human action and / or automatically.

[0067] In this way, the plant can be controlled automatically through software, as if it were a treatment plant, but also individually, providing space for scientific development and research into better processes, methods and good practices.

[0068] This controller, configured with control software, also has the capacity to collect data and allows the parameterization and activation of all station elements, which can be viewed schematically or in 3D, according to pre-defined representation standards.

[0069] Data collection allows for direct intervention in real-time process improvement or can be used in conjunction with machine learning. This station can thus be equipped with a set of in-line sensors and actuators to enable continuous process control, as well as analysis of the preliminary characteristics of raw water and final treated water, such as pH, conductivity, and free chlorine.

[0070] Each sensor or actuator can be installed on a face of a corresponding reservoir, for example, on a side face or a top face. The top face can be formed by a reservoir lid, thus being removable from the reservoir.

[0071] The station elements of the present disclosure, such as reservoirs, inlets and outlets, pumps, or valves, may be connected by piping and corresponding coupling elements. These piping and corresponding coupling elements may be standardized.

[0072] The pipes, sensors, actuators and fixing supports can be coupled using quick-connect and quick-fix coupling elements, allowing for easy configurations without the need for special tools and also providing expanded learning and research skills.

[0073] The water treatment method of the present disclosure consists of a method for treating water in the water treatment plant of the present disclosure.

[0074] The method comprising the steps of:

[0075] • add water, optionally demineralized water, to the first reservoir,

[0076] • open the water outlet of the first reservoir and pump water to the second reservoir,

[0077] • add at least one contaminant to the water pumped to the second reservoir, obtaining contaminated water,

[0078] • adding at least one reagent to the contaminated water, the mixture thus incurring a reaction such as an oxidation-reduction reaction,

[0079] • wait for the deposition of residues present in the initial solution at the bottom of the second reservoir,

[0080] • open the water outlet of the second reservoir and obtain water treated for the contaminant at the water outlet of the station. The method may additionally include determining the volume of water contained within the first reservoir (B101). Water pumping may be performed based on the determined volume of water contained within the first reservoir (B101). Pumping of the first pump (P121) may stop when the determined value of the volume of water contained within the first reservoir (B101) is zero or close to zero. Pumping of the first pump (P121) may be continued when the determined value is greater than or equal to a predefined value.

[0081] The method may further include determining a water flow rate between the first reservoir (B101) and the second reservoir (B102), and water may be pumped based on this determined flow rate. The first pump (P121) may stop pumping when the determined flow rate for a period of time is greater than or equal to a pre-defined value. The first pump (P121) may continue pumping when the determined flow rate for a period of time is less than or equal to a pre-defined value. As an example, the pre-defined value may correspond to a maximum volume, this maximum volume corresponding to a total volume of the second reservoir (B102) or to a pre-established volume for carrying out an experiment in the second reservoir (B102).

[0082] As a method for treating water in the water treatment plant of the present disclosure, it may specifically include the steps of:

[0083] • add demineralized water to the first tank (B101) as a solid and neutral base for the experiments to be carried out,

[0084] • open the water outlet of the first reservoir (B101) and pump water into the second reservoir (B102), in the correct quantity and programmed according to the experiment to be carried out,

[0085] • activate or not the aeration pump (P112),

[0086] • activate and regulate the mechanical agitator (Mill) based on experience and research to ensure homogenization of the contaminant inserted in the next step,

[0087] • add a synthetic sample (contamination),

[0088] • add a chemical reagent,

[0089] • adjust the mechanical stirrer (Mill) according to the reagent,

[0090] • wait for the oxidation process of the residues present and deposition at the bottom of the second reservoir (B102), • open the water outlet of the second reservoir (B102) to obtain pre-treated water at the water outlet of the station,

[0091] • open the outlet for waste deposited in the lower part of the second tank (B102),

[0092] • analyze pre-treated water collected from the second reservoir (B102), and / or

[0093] • analyze the collected waste.
