Three Stage Water Treatment System Deep Degree Water Purification Systems For Zero External Discharge

High efficiency fiber filter is a pressure fiber filter equipment with advanced structure and excellent performance. This new energy-saving water purifier effectively removes suspended solids while providing significant removal of bacteria, viruses, macromolecular organic matter, colloids, iron, manganese, and other contaminants, successfully solving problems associated with granular filter media.

High efficiency cation exchangers (sodium beds) are classified by resin regeneration agents into hydrogen type and sodium type. Sodium type cation exchangers are called softeners or sodium ion exchangers. Ion exchange capacity can become saturated or polluted by suspended substances, colloidal substances, organic matter, bacteria, algae, iron, manganese, and other pollutants during long-term use. Irregular regeneration treatment can be performed based on actual conditions to restore capacity.

Macromolecules secreted by bacteria complex calcium and magnesium ions in water, forming precipitates that can be eliminated through sewage or by-filtration, further reducing hardness and providing scale inhibition. Calcium carbonate particles are complexed and biological slime is dissolved, loosening the scale layer and enabling peel-off under water flow erosion, achieving effective scale removal.

Through dissolved oxygen consumption, our technology effectively prevents pipeline corrosion, intercrystal corrosion, stress corrosion, cavitation corrosion, scaling corrosion, and microbial corrosion.

Our biological agents contain no eutrophication components such as nitrogen and phosphorus. The bacterial community in discharged water can degrade environmental organic matter and clean environmental water bodies, preventing secondary pollution.

Under identical conditions, circulating water concentration ratio is higher than with chemical agents. Numerous practical cases demonstrate 10%-20% water savings.

RO reverse osmosis is an advanced membrane separation technology that uses reverse osmosis membranes to separate solvent from solute in solution under pressure. With RO membrane pores measuring 0.0001 micron (one millionth of hair width), invisible to the naked eye and 5000 times smaller than bacteria and viruses, water molecules pass through under pressure while inorganic salts, heavy metal ions, organic matter, colloids, bacteria, viruses, and other impurities are separated and discharged through wastewater pipes.

Key Advantages

Systematic Approach

Tailored to different circulating water qualities, the system applies a combination of physical, chemical, and biological technologies at three key stages—make-up water, operation, and blowdown—to effectively address scaling issues and achieve ultra-low discharge. 

Intelligent Control

Integrated with the CIMS O&M platform, the system enables automated, closed-loop management of equipment and chemical dosing, significantly reducing manual workload.

Low Cost

Featuring a modular design for standardized assembly and maintenance, along with a remote expert support system, the solution greatly reduces both initial investment and ongoing operational costs.
