Continuous Sand Filter
The continuous sand filter is a high-efficiency filter integrating coagulation, clarification and filtration. The system uses upflow fluid bed filtration and a single homogeneous quartz sand filter material.
Send InquiryContinuous sand filter Introduction
Filtration and sand washing are carried out at the same time. It can operate continuously and automatically for 24 hours without backwashing. The sand lifting and sand washing structure replaces the traditional high-power backwash system.Energy consumption is extremely low.

Equipment characteristics
The filtering process of the continuous sand filter is based on the counterflow principle. The raw water enters the inside of the filter from top to bottom through the water inlet pipe, is evenly distributed by the water distributor, and then rises upward. The filtration is completed through the filter material layer, and the filter liquid is collected on the upper part of the filter. Outflow through overflow weir. In this process, the raw water is filtered, the content of pollutants in the water decreases, and the content of pollutants in the quartz sand increases, and the content of pollutants in the lower filter layer is higher than the upper filter material. At the same time of filtering, the air compressor supplies air to the air control cabinet, and the air control cabinet distributes air to the air lift pump located in the middle and lower parts of the filter. Under the action of the air lift pump, the quartz sand trapped with pollutants in the bottom layer is lifted to the filter The sand is washed at the top of the device, and the sand particles are returned to the filter bed after cleaning, and the pollutants generated by the cleaning are discharged through the flushing water discharge pipe. In this process, the sand at the bottom is continuously cleaned by the air-lift pump to the sand washer at the top. Therefore, in the filter, the sand outside the filter element sinks, and the raw water rises after being released by the water distributor Yes, so the flow of sand and filtered water is relative and reverse.
Application
Active sand filters are widely used in various water treatment occasions that need to be filtered, especially for the purification of industrial process water, sewage and industrial wastewater, and can remove suspended solids and colloidal substances in water.
Continuous sand filter system consists of sand filter tank, water inlet pipe, water distributor, sand pump, sand washing device, quartz sand (homogenization coefficient 1.4), filtrate outlet pipe, rinse water outlet pipe, air compressor and control System and so on. The equipment has a low operating cost and does not require a high-lift and large-flow backwash pump. High efficiency, 24 hours of continuous work, no need to stop backwash, no need to backwash valves and spare filters. The active sand filter has no rotating parts other than quartz sand filter material during operation, which has low failure rate and low maintenance cost. The water head loss is small. Because the single-stage filter material is used and the filter material is clean and timely, the water head loss of the active sand filter is very small, about 0.6m. The influent water quality requirements are loose, the filtering effect is good, and the effluent water quality is stable. The filter material is clean and timely, which can ensure high-quality and stable water outlet effect without periodic water quality fluctuations.
