Introduction
The shallow sand filter is composed of one or more standard high speed sand tanks. It is equipped with unique water distributor, water collector and unique automatic washing valve. It can realize multiple standard high speed sand tanks one by one backwashing in the normal system operation process, which is controlled by automatic program. The shallow sand filter has the advantages of small backwashing water consumption, convenient installation and easy operation. The flow of the equipment is large, no maintenance. According to different user requirements, we designed two series: vertical type and horizontal type, which is suitable for water treatment demands in different fields.
Advantages
1)Automatic backwashing system: modular design from inside to outside, forward filtratioin and reverse backwashing.
2)Automatic control system: intelligent control system is sensitive, accurate, simple and easy to operate.
3)High performance precision filter element: V-shaped slit precision filter element: V-shaped opening has good backwashing effect and is not easy to jam impurities.
4)Advantages of overall structure: the overall equipment structure has no consumables, less vulnerable parts and low operation cost.
Working Principle
First of all, the water passes through the coarse filter at the inlet to remove the larger impurities, and then passes through the fine filter to remove the smaller impurities. In the filtration process, the fine filter gradually accumulates dirt and impurities, forming a impurity layer which is piled up in the inner side of the fine filter screen, then a differential pressure is formed on the inside and outside sides of the fine screen.
When the pressure difference of the filter reaches the preset value, the automatic self-cleaning process will begin, the water supply is not cut off during this self-cleaning process; the sewage discharge valve is opened, the water pressure in the cleaning chamber and the sewage suction pipe greatly decreases, and there will be a pressure difference between the filter element and the sewage suction pipe, the suction pipe and the cleaning chamber will produce a suction process through the suction nozzle, forming a sewage suction process. At the same time, the electric motor drives the suction pipe along the axial spiral movement. The combination of axial movement and rotary movement of the suction pipe will completely clean the inner surface of the filter screen. The whole process takes only a few seconds. The drain valve closes at the end of cleaning. The filter begins to prepare for the next flush cycle.
