1. What is Greensand County USA?
Greensand USA is a type of water filter manganese manufactured according to the industrial model, from the USA. Greensand USA seeds can remove iron, and Arsenic components in water perfectly.
2. Application:
- Raise and stabilize the pH of water in the range of 6.5-8.0
- Catalyze iron reduction process (Fe < 35 mg/l)
- Reduce the content of nitrogen (nitrite, nitrate, ammonium), phosphate (20-50% depending on the filtration speed from 4-7 m/h), capable of reducing arsenic, reducing fluorine in water (the effect is similar to catalyst particles). Alumina works).
- Reduce the content of some organic compounds in water
- Removal of heavy metals such as copper, zinc, chromium, nickel
- Reduced oil content (absorbs about 90 mg of oil/g seed)
- Eliminate radioactive substances

4. Advantages:
- Greensand USA seeds can combine many different processing stages such as catalysis, flocculation, sediment filtration in the same device.
- Increased safety for water quality after treatment.
- Simple operation.
- It is possible to replace the filter materials being used without changing the filter tank structure.
- The amount of filtered water is lower than other materials, no need for aeration.
