1. Quartz sand filter material
It mainly purifies water through interception and filtration, removes suspended impurities in water, improves water transparency and reduces turbidity. Routinely used for river water purification, sewage purification, surface water treatment, etc.
2. Activated carbon
It can absorb organic matter and metal ions in water, deodorize and deodorize. Generally used for water reuse, tap water, sewage treatment, decolorization and deodorization, and activated carbon for drinking water can improve the taste of water.
3. Manganese sand filter material
It mainly removes iron and manganese ions in water. It is mainly used for groundwater treatment, well water treatment, rust removal of metal pipes and waste water with high iron content.
4. Anthracite
It is a kind of filter material between quartz sand and activated carbon. It has the function of filtering and intercepting quartz sand and also has a certain adsorption effect of activated carbon. It is often used in tap water treatment, river water treatment and sewage treatment. The disadvantage is that the cost of filter material is high.
5. Fiber balls
It is often used for water treatment with large flow rate. Because of its fast flow rate, the flow rate per unit cross-sectional area is large, and it has obvious effect on oil treatment. Generally used for oil removal filtration and large flow landscape water treatment, river water treatment, sewage treatment.
