Steel mill
The water used in steel mills (steel rolling/steel making) focuses on large-volume cooling water circulation; it includes direct water (contact products) and indirect water (equipment cooling); soft water/pure water; and part of wastewater treatment.
Direct water：
Filtered water is usually used. Because the contact with the product will bring a lot of iron filings, oil stains, etc., when the water is reused, these impurities must be effectively removed to make the production process go smoothly.。
Indirect water：
For steel mills, it mainly includes copper mold cooling, mechanical cooling, C.C. Spray cooling, and emergency water systems. Soft water is usually used to avoid fouling and damage to the equipment.
