Raw water - raw water tank - original water pump - sand filter - carbon filter - fine filter - RO host - pure water tank - pure water pump - yin and yang mixed bed - fine mixed bed (optional) - filter - Water point；

The role of the original pump:

Increase the water pressure, can effectively rinse sand, carbon。

Sand filter

Quartz sand filter is the need to filter the water pumped by the pump (about 0.3-0.4Mpa), through the filter layer to achieve the purpose of filtration, so also known as pressure filter, quartz sand filter cylinder filled with different diameter filter Material, from bottom to top according to the size of compaction arrangement. When the water flow from top to bottom filter layer, the water contained in the suspension material into the upper layer of the formation of micro-porous media, by the adsorption and mechanical resistance flow, suspended solids by the filter layer was retained. At the same time, these suspended suspended matter between the occurrence of "overlap" and "bridge" role in the filter layer to form a thin film, continue to filter, which is the so-called filter film surface membrane filtration effect.

The system configuration specifications for the Ф400 × H1650 filter, filter filled with different particle size of the filter, the filter layer height 1160mm, design flow rate of 16m / h, the total water production is about 2.0m3 / h.

Role: blocking the suspended solids in the water, impurities,
