Sand and gravel filter is mainly applied to water quality filtration, which can settle sediment well and make water quality not blocked.
Sand and gravel filter is one of the media filters. Its sand bed is a three-dimensional filter, which has a strong ability to intercept dirt. It is suitable for deep well water filtration, agricultural water treatment, various water technology front pretreatment, etc. It can be used in factories, rural areas, hotels, schools, gardens, water plants and other places. Among all filters, sand and gravel filters are most effective in treating organic and inorganic impurities in water. This filter has strong ability to filter out and retain impurities and can supply water without interruption. As long as the content of organic matter in water exceeds 10mg/L, sand filter should be selected regardless of the content of inorganic matter.
Three layers of grit filter
Product features:
The filtration speed is high, and the pressure loss is small, which solves the problem of slow filtration speed and small flow of ordinary filters.
Reasonable design, small area, less piping, and less investment
It is flexible and convenient to use, and it can be combined flexibly according to irrigation project quantity and filtration requirements.
1. It is suitable for treating river water, reservoir water, channel water, lake water, municipal circulating water and other pipeline water or trench water containing a large amount of suspended dirt with organic matter content exceeding 10mg/L, and is usually used as a primary filter.
2. The filter tank is of metal structure, and the surface adopts automobile baking paint technology, which will not fade after long-term outdoor use; The anti-corrosion and anti-rust performance is enhanced, and the service life of the tank is long.
3. The inside of the tank adopts a double-layer structure. The upper part of the filter plate is a sand bed and the space where impurities remain, and the lower part is a clear water circulation space. And there is a drain outlet at the bottom of the tank to remove the dirt that may be deposited on the bottom from the bottom at any time.
