Multi-tank automatic backwash water treatment equipment

Product introduction

Side filter, also known as shallow sand filter, is mainly used in the industrial field of circulating water, water supply, and wastewater filtration. HGBMF's media 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 be absorbed to remove the corresponding organic matter, ions, etc. 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 inlet of the filter tank and uniformly reaches the filter material layer. When the water filter material layer, suspended solids are intercepted by the filter material. At the bottom of the filter is a water collector with a precise gap. The filtered water is evenly collected and discharged from the filter. The precise gap on the 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 an increasing pressure difference. With the continuous accumulation of impurities in the filter material layer, the pressure loss is increasing. 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, so that 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
