Multi - tank automatic backwash water treatment equipment

Product Introduction

Multi-tank automatic backwash water treatment equipment is mainly used in industrial areas of circulating water, feed water, and wastewater filtration. HGBMF's medium filtration system utilizes deep media to effectively remove particulate matter and reduce turbidity. If loaded with a specific filter material, such as activated carbon, zeolite, can also adsorb the corresponding organic matter, ions and so on. The fluidization device in the system (bottom drainage device) can fluidize the filter medium, remove the pollutants trapped in the medium, and discharge them, and get a thorough cleaning.

Mode of operation

When the system is in the filtering state, the pressurized water flows into the water distribution system from the filter tank inlet and uniformly reaches the filter material layer. When the water filters the material layer, the suspended matter is intercepted by the filter material. At the bottom of the filter is a water collector with a precise gap, and the filtered water is uniformly collected and drained out of the filter.

The precise gap on the water collector can effectively prevent the loss of filter material. Mechanical battlements (pneumatic or electric) control the flow of water.

When the system is in the automatic backwash state, the backwash cycle is controlled by increasing pressure differences. With the continuous accumulation of impurities in the filter material layer, the pressure loss continues to increase, when the pressure difference increases to a certain set value, the system will automatically switch to the backwash state.

Pressurized water enters the filter material layer through the fluidization device (i.e. the water collection device), scour it, and make the trapped pollutants fall off and discharge out of the filtration system. After the backwash lasts for at least 2 minutes, the valve automatically switches the system to the filtered state.
