Filter, that is, the raw water through a variety of media in the filter layer, support retention, adsorption of various impurities in water, organic or inorganic substances, and microorganisms such as bacteria and viruses, the raw water through a filter, the turbidity decreased, while the organic raw water or inorganic impurities, bacteria, viruses, and so oil will be reduced with a lot of turbidity removal, and strengthen follow-up disinfection. Due to increased suspended solids and other impurities removal, which can reduce the amount of disinfectant; and make follow-up of the ion exchange, adsorption, membrane processes are often blocked at the treatment plant rabbit to improve its processing efficiency.
Mechanical filter from the tank, valves, filter, whose performance depends on filling the filter, water quality and water treatment based on the use of selected media. Many types, I can provide the following filter:
1, quartz sand filter: built-in a variety of fine quartz sand, according to a certain level with filler, primarily used to remove suspended solids, small particles and colloidal substances, is an indispensable pre-treatment equipment, the filter can also be filled with manganese sand, iron and manganese ions removal, to water purification purposes.
2, activated carbon filters: built-in activated carbon, activated carbon surface area, very strong adsorption, and adsorption in the water it can remove more than 99% of free chlorine, color, smell, odor, etc., through the backwash to remove organic or inorganic impurities, microbes and bacteria. It is often combined with quartz sand filter used together, it is indispensable to conventional water treatment equipment is widely used.
3, multi-media filter: the filling of a variety of quartz sand and anthracite coal, mainly used to remove suspended solids, small particles, with a high flow rate, handling large volume of water features.
I produced a filter with single-column valve control plane / parallel operation of five columns, the use of liquid switching principle, automatic operation, backwashing does not find another water source is the only patented technology unique, self-backwashing, long cycle , anti-washing time is short, small footprint, easy installation, no auxiliary equipment, water, electricity.
