进口浅层介质过滤器Product description:

It is an efficient filtering device that uses natural sea sand as the filtering medium to filter water with high turbidity through a certain thickness of granular or non granular natural sea sand under a certain pressure, effectively intercept and remove suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odor and some heavy metal ions in the water, and finally achieve the effect of reducing water turbidity and purifying water quality. The fully automatic shallow sand filter is a spherical shell and unique internal structure design to ensure smooth water flow and good filtering effect. Backwashing is to form innumerable internal circulations with high backwashing effect. Compared with traditional sand filter, it has full automatic filtering.

进口浅层介质过滤器characteristic:

When the system is in the filtering state, the unfiltered water passes through the upper water distributor and cooperates with the spherical shell to reach the packing layer in the filter in a state close to horizontal flow. When water flows through the packing layer, impurities are trapped in the packing layer. The collector at the bottom of the filter collects and discharges the filtered water evenly. Horizontal flow filtration determines that the filter can still achieve good filtration effect at high flow rate.

进口浅层介质过滤器As impurities continue to accumulate in the packing layer, the head loss (i.e. pressure difference) will continue to increase. When the differential pressure reaches

When a certain set limit is reached or the filtering time reaches the set value, the system will automatically switch to the backwashing state to clean the filler layer and remove the accumulated impurities. For the system, regular backwashing is necessary to remove the accumulated impurities.

When the system enters the backwashing state, the on-off position of the three-way valve is changed through PLC control (the inlet is closed, and the exhaust

The sewage port is opened), and the filtered water in other filter tanks flows into the filter tank to be backwashed. As the system pressure is flushed by the impact of water flow, the filler layer of the backwashing filter unit is flushed up, and impurities are discharged through the drain outlet of the three-way valve.

In the BTSL system, the specially designed water collector enables the packing layer to form an internal loop flow during backwashing, and the fillers rub against each other to improve the backwashing efficiency, reduce the backwashing water required, and at the same time, do not run away during backwashing.
