Working Principle and Composition:
The recyclable water is used for filtration and purification. According to the influent water quality and the effluent water quality requirements, appropriate return water treatment equipment is selected. According to the purification requirements, quartz sand filtration, activated carbon filtration, and precision filtration can be used such as (UF) system and reverse osmosis (RO) system. Each filtering device has different filtering accuracy and filtering function, according to the filtration and purification requirements, the above system combination of multiple filtering modules can be used to achieve the purpose of purifying water quality and recycling. . (According to the production of water quality and water requirements, can be customized)
Filter Device Function Table:
Quartz sand filter
As the name implies, the filler is quartz sand, which is mainly used to retain and adsorb sediment, colloids, suspended matter, and organic matter through quartz sand filter material. The filtration accuracy is between 0.005-0.01m. The main function is to reduce the turbidity of water. Automatic back and forth flushing can be used to avoid fouling and long-term effective operation.
Activated carbon filter
As the name implies, the filler is activated carbon. The activated carbon particles have a lot of micropores and a large specific surface area. They have strong physical adsorption capacity and can effectively absorb residual chlorine in the water. They are more odor in water, colloids and pigments, heavy metal ions, COD, etc. Obvious adsorption removal effect; equipment can be automatically back and forth flush, to avoid fouling, long-term effective operation.
Also known as the security filter, the cylinder shell is generally made of stainless steel, the internal use of PP melt-blown, wire wound, folded tubular filter element or filter bag as a filter element, the filtration accuracy from 0.1-60um, tubular filter length 10, 20, 30, 40 inches and other sizes, can further improve the water quality, filter elements need to be replaced.
Ultrafiltration (UF) equipment
Ultrafiltration (UF) membrane is a membrane separation technology. The membrane separation process is driven by water pressure. Ultrafiltration technology is playing an increasingly important role in reverse osmosis pretreatment, drinking water treatment, and reuse of reclaimed water. The role of ultrafiltration filtration accuracy in the range of 0.01-0.01μm, can effectively remove water particles, colloids, bacteria, viruses, proteins, microorganisms and organic macromolecules.
Reverse osmosis (RO) equipment
Reverse osmosis (RO) filtration is also a membrane separation technology with a filtration accuracy of up to 0.00001 μm. To obtain a purer water treatment device, the mixed bed and EDI module can be added to the rear of the (RO) system to further increase the purity of water.
