High speed shallow sand filter filter water, filtering effect is good, fast filtering flow rate, the normal filter speed can be about 40m/h, according to the water quality can reach 60m/h; Filter backwash using product water, and do not have booster pump and backwash pump; The backwashing time is 2-3min, and the backwashing water is less than 3m3. High filtration accuracy, impurity filtration accuracy can be less than 0.10mm, effluent turbidity can be less than 0.5NTU.

High filtration accuracy, impurity filtration accuracy can be less than 0.10mm, effluent turbidity can be less than 0.5NTU.
The filtration system consists of a standard unit sand cylinder, and the filtration flow rate can be increased from 30.6 m3 / h to 2500 m3 / h. Automatic backwashing: The backwashing of the equipment is automatically identified and controlled by the intelligent control system without manual intervention. Even if the suspended matter in the water fluctuates, the equipment may automatically adapt. Shallow sand filter water supply uninterrupted; When the equipment is backwashed, the filtration process is carried out at the same time, and the system provides water as usual. The unique cloth and water collection device is adopted. The unique water distribution system and the very uniform water collector make the water flow in the whole filtration process in the layered flow, the filter sand bed plane is always smooth in the filtration process, and the water quality is stable. The system has a unique automatic backwashing valve. The backwashing of the sand filter tank is not carried out simultaneously, but under the normal operation of the system, it takes turns to backwash one by one. There is no need to consider setting the backwashing water pump.
1. Industrial water filtration - there are certain system requirements for water quality. Such as: steel oxygen gun water, boiler, heat exchanger water filtration, can filter out the impurities in the water, to avoid the blockage of several nozzles in the pipeline.
2. It is used for industrial water, domestic water and municipal water supply system whose effluent turbidity is less than 5mg/L and can meet the drinking water quality standard;
3. Removal of suspended matter and solid matter in industrial sewage;
4. It can be used as pretreatment equipment in softening and desalting system by ion exchange method, and crude filtration equipment for industrial water supply with low water quality requirement. And used in swimming pool circulation treatment system, cooling circulating water purification system, etc.
5 raw water treatment - surface river water, lake water, sea water, reservoir water, well water and urban tap water as a source of urban small quality water supply filtration, remove the sand in the water, suspended matter, algae, organic matter and so on.
