Problems solved by technology

However, as mentioned above, reverse osmosis membranes or nanofiltration membranes are high maintenance and require additional equipment for chemicals or ion exchange resins
Therefore, there are limitations in application to small-scale water treatment products such as water purifiers

experiment example

[0073] The flow rate, zeta potential, particle removal rate and hardness removal rate of the filter manufactured under the conditions of the embodiment shown in Table 1 above were measured to evaluate the performance of the filter. The results are shown in Table 2.

[0074] [Table 2]

[0075]

[0076]

[0077] High performance per filter with a higher amount of raw material used in making a filter with a basis weight and a higher zeolite content, and with a higher amount of added zeolite, the thickness of each filter smaller.

[0078] The pores of the filters according to Examples 4 to 6 are 0.81 μm to 0.84 μm, which are the smallest pores, and the zeta potentials of the filters according to Examples 4 to 6 are 15.9 mV to 18.5 mV, which is relatively high .

[0079] The flow rate of the filters according to Examples 7 to 12 was 2.23 LPM to 2.45 LPM, which is a relatively large amount of water transfer. However, the 1 μm-sized particle removal ability of the filters a...

Abstract

The present invention relates to a water treatment filter and a method for manufacturing same. More specifically, the present invention relates to a water treatment filter and a method for manufacturing same, the method comprising the steps of: mixing positive charge additives, glass fibers, binder fibers, cellulose, zeolite powder, and water; and molding the resulting mixture.

Description

technical field [0001] The present invention relates to a water treatment filter and its manufacturing method, more particularly to such a water treatment filter and its manufacturing method, said water treatment filter comprises positively charged additives, glass fiber, binder fiber, cellulose And zeolite to effectively remove hardness substances and various pollutants in water. Background technique [0002] Water treatment filters are used to remove various pollutants contained in water. In the primary removal mechanism, contaminants are removed by the sieving effect, where material with a size larger than the pore size in the filter does not pass through the filter and material with a size smaller than the pore size passes through the filter. [0003] Generally, water treatment filters are used in water purification plants, sewage treatment plants, various industrial sites, and air purifiers used in offices or homes. [0004] Filters can be mainly classified into rever...
