The working principle of sand tank

  The filter sand tank is a pressure filter container. The cylinder body is made of glass fiber reinforced materials, which is strong, wear-resistant, corrosion-resistant and not easily deformed. According to the structure, it is divided into top-out filtering sand tank, side-out filtering sand tank, commercial large sand tank, horizontal sand tank, etc. The uniquely designed water distributor can evenly stabilize the water flow, and the culvert drainage system has high efficiency. Easy to install, easy to repair and maintain.

  What is the working principle of the sand tank? We all know that the swimming pool sand tank should be filled with quartz sand, why should we fill it with sand? Because water can seep into the ground and become clear groundwater. We can do a simple experiment to find that we can filter out clean water by pouring turbid water into the sediment layer and filtering it. The sand tank uses this principle. When the pool water passes through the sand tank, the impurities in the water will be trapped by the sand, and the clear water will flow back to the pool through the pipe.

  The stones filled in the tank are quartz sand, and it is these special sand filters that filter out the tiny impurities in the pool water. The sand filter does not have to fill the entire sand tank, it is about 2/3 of the position. When the sand tank is working normally, the pool water containing suspended dirt particles is pressed into the filter pipeline by the circulating pump, and then is guided by the control switch to the outlet of the filter. The pool water is filtered through a sand tank, and tiny dirt is intercepted and filtered out by the sand bed. The filtered clean water returns from the bottom of the filter to the swimming pool through the control switch through the pipeline. This whole set of procedures is continuous and automatic, and forms a complete circulation system for the pool sand tank filter and the pipeline.
