Nutshell filter characteristics: 1. Nutshell filter with a multifaceted and microporous, interception and strong, oil and suspended solids removal. 2, Nutshell filter with a multi-row and different sizes, forming a deep bed filtration, enhanced oil capacity and filtration rate. 3, Nutshell filter with hydrophilic and lipophilic appropriate proportion, backwash, regeneration and strong. 4, Nutshell filter hardness, and the special treatment is not easy to corrode shell activated carbon Which is good, do not replace the wholesale shell activated carbon filter, only add 10% per year, reducing maintenance costs and maintenance time and improve efficiency. Manganese sand filter has the best water filter gradation proportion, making it the largest in the unit volume has a specific surface area, the strongest interception capability, maximum and minimum oxidation catalysis backwash turnover. Manganese sand filter appearance of rough brown or light gray, commonly used in drinking water addition to iron, manganese filters, water treatment effect is very good. (Note: MnO2≥35% either iron shell activated carbon, but in addition to manganese, MnO2≤30%) can only be used for groundwater iron) manganese sand filter is mainly used to reduce the total amount of iron in water ferromanganese and manganese , the iron content of groundwater in some areas up to 5 ~ 10mg / L, there are high to 20 ~ 30mg / L, manganese content of up to 0.5 ~ 2.0mg / L, more than 2mg / L or even individual up to 5 ~ 10mg / L of also used to find. China's "drinking water standards", the content of iron in drinking water should not exceed 0.3mg / L, manganese content of not more than 0.1mg / L, must be dealt with when exceeded. Therefore groundwater iron, water color change after that is excessive as manganese content; red black _ _ _ yellow will give life, the production of water will cause a great impact.
