Introduction Of The ASME Code Sand Filter

Mechanical filter uses one or multi filter media, according to the different filter media can be divided into quartz sand filter, activated carbon filter and manganese sand filter and multi-medium filter. Under a certain pressure, the high turbidity of water through a certain thickness of granular or non-granular materials, so as to effectively remove suspended impurities and liquid clarification process. It is an important part of pure water preparation pretreatment and fluid purification system.

The mechanical filter can be divided into single flow filter and double flow filter which can be used in combination or separately according to the actual situation.

This device is used in the first filtration of water treatment. It consists in 304stainless steel. There is quartz sand inside. It divides coarse sand, medium sand and fine sand. It can remove dirty and other big particle
