Filtration Process When the system is in the filtration state, unfiltered water passes through the three-layer water distributor, and with the specially designed shell, reaches the packing layer in the filter in a state of near advection. When water flows through the packing layer, impurities are trapped within the packing layer. There is a mushroom-shaped filter water collector at the bottom of the filter, which collects the filtered water evenly and flows out. Advection filtration determines that the filter can filter at high flow rates and still achieve better filtration effects. During the backwash process, as impurities continue to accumulate in the packing layer, the head loss will continue to increase. When the water head loss reaches a certain set limit, the system will automatically switch to the backwash state to clean the accumulated impurities. Frequent backwashing is necessary for the system to remove accumulated impurities. When the system is in backwash state, a certain filter will flow clean filtered water through a three-way backwash valve into the filter simultaneously. During this counterflow process, the packing layer of the backwashed filter unit is flushed up under the impact of the water flow, and the impurities are discharged through a three-way backwash port. In the filtration system, the specially designed water collector causes the filler layer to form an internal circulation during backwashing. The fillers scrub each other, maximizing the backwashing efficiency and reducing the required backwash water. At the same time, there is no need for backwashing. Running sand. When the backwashing is completed, the valve returns to the filtering state and the next filter is ready to enter the backwashing state. The performance characteristics of the media filter are high-efficiency sand filter filters. The height of the filter media is high in filtration accuracy and high suspended matter removal rate. The filter media is adsorbent and can effectively reduce turbidity. The filter tank is made of carbon steel, painted inside and outside and contains a high-strength polyester protective layer above microns. Combined with fluid optimization calculations, it ensures that the inner paint layer will not wear out during filtration and backwashing. Therefore, while obtaining the best filtration effect, the service life of the tank is extended, and secondary induced clogging caused by tank corrosion is avoided. The tank body has a double-layer structure. The upper layer is the filter media bed and impurity retention space, and the lower layer is the clean water flow space. The water distributor enables the unfiltered water flow to flow evenly through the filler layer even under high flow conditions, and maintains a flat water surface on the filler layer. The unique mushroom-shaped pressure difference compensation filter water collector balances the water pressure of each part of the system in the filtering state. The filtering flow rate is high and the efficiency is high. In the backwashing state, an internal circulation is formed. During the backwashing process, the water separator A vortex is formed to ensure that the dirt is completely backwashed out of the filter tank without sand running away. The fully automatic control filtration system adopts a modular design and uses different numbers of filters according to the flow rate. The system operates fully automatically and does not require special supervision. Backwashing can be started automatically using various methods such as time and pressure difference. Each filter in the system is backwashed in sequence, while other filters are still filtering to ensure that the system does not interrupt the water supply during the backwashing process. Backwashing saves water, and the system can perform source backwashing. The backflush efficiency is high, the backflush time is short, and the water consumption during backwash is less than the amount of filtered water. It is convenient to install left and right compared to traditional sand filters. The system is light in weight and does not require a special foundation. Generally, a flat cement floor will suffice.
