Dia1.4m manganese greensand filter system for drinking water treatment

Product Overview

Description

Introduction 
Iron and manganese (Fe/Mn) are common in groundwater supplies used by many Forest Service water systems. Iron is the more frequent of these two contaminants, but they often occur together. High levels of these contaminants can result in discolored water, stained plumbing fixtures, and an unpleasant metallic taste to the water. This can lead to employee and visitor complaints about the water. Iron deposits can buildup in pressure tanks, storage tanks, water heaters, and pipelines. Iron-deposit buildup can decrease capacity, reduce pressure, and increase maintenance. These deposits can also cause self-closing valves to stick. 

High levels of iron and manganese do not pose any known adverse heath risks. The U.S. Environmental Protection Agency (EPA) has not set maximum contaminant levels (MCL) for iron and manganese in the National Primary Drinking Water Regulations. Secondary maximum contaminant levels (SMCL) recommended in the National Secondary Drinking Water Regulations are set for esthetic reasons and are not enforceable by EPA, but are intended as guides to the States. The SMCL for iron is 0.3 milligrams per liter (mg/L) and the SMCL for manganese is 0.05 mg/L. States may adopt SMCLs as guidelines or enforce them as contaminants. FSM 7400-Public Health and Pollution Control Facilities requires all Forest Service water systems to comply with the SMCLs.

 

What Is a Green Sand Filter?

A green sand filter uses manganese green sand to filter iron, sulfur, hydrogen and manganese out of household and drinking water. Water polluted with these materials may stain, smell like rotten eggs, be discolored, taste bad and possibly be unsafe to drink. Reducing the impurities in water can help improve the safety, taste and smell of drinking water.

How Does a Green Sand Filter Work?

A green sand filter contains manganese green sand, which forces impurities in the water, such as iron, to oxidize. The oxidized impurities are then trapped in the sand and held there. Typically, a water purification filter that includes a green sand filter will also include water-purification and disinfectants.

How Long Will a Green Sand Filter Work?

When the green sand filter has become exhausted, it may be regenerated through the backwash process with potassium permagranate. When properly cared for and regularly backwashed, the green sand filter will last for many years.

 

Description of Manganese sand filter:

Manganese sand filter is selected by natural manganese sand or manganese ore, grinding and sieving to various kind of manganese sand filter media. Main ingredient is MnO2, its content between 35% and 45%. It appears rough, spherical, and brown or light gray and is commonly used in drinking water filtration device to remove remove the Manganese and Ferrum in the water effect is very good.

Manganese sand filter is a strong antioxidant , to oxidation ferrous up oxidation role in water , usual used in drinking water in addition to iron and manganese removal filter device, groundwater for removing iron and manganese purification of water use.

The Manganese sand filter Advantages:

1.    High-quality raw material and great grain density;
2.    High mechanical strength and stable chemical property;
3.    Large specific surface area and good adsorption;
4.    High chemical activity and good oxidation and catalysis effect;
5.    Great effect on deferrization and demanganization;
6.    Harmless and long service life.
