ZPG automatic backwashing sewage filter
Other Products
I. Introduction:
The automatic backwashing sewage filter is a filter that can treat low-quality water for industrial cooling, and it can also be used in other process flows requiring filtration. It has the function of flushing and removing impurities, and is generally installed in front of other actuators of heat exchangers to regularly clean and remove impurities. Under normal conditions, the diverter valve opens, and water flows through the filter cartridge and is discharged from the outlet. When the diverter valve closes and the blowdown valve opens, water is forced to enter the outer side of the filter cartridge through the mesh at the inlet section of the filter cartridge. Most of the water flows out from the outlet, and a part of it enters the interior of the filter cartridge through the mesh at the impurity collection section outside the filter, creating backwashing on the filter cartridge, achieving the effect of flushing impurities adhering to the mesh from the outside of the filter cartridge, and the impurities are still discharged through the sewage outlet.
II. Product Features:
1. Continuous water supply: The water consumption during cleaning is extremely low, only 5% of the filter's water output, with a flushing time of 2 to 15 seconds, ensuring the entire system maintains continuous water supply.
2. High filtration precision: The maximum filtration precision can reach 20 microns, and filter screens of various precision levels are available for selection.
3. Large filtration area: The effective filtration area of the standard filter screen is 7 to 40 times the area of the inlet.
4. Reliable cleaning: Multiple control methods are available, including manual, differential pressure, time, and PLC program logic control, among others.
5. Economical and simple installation: It has diverse structural forms, suitable for installation in various on-site conditions without affecting operational performance.
6. Long service life: Under normal conditions, it has a service life of more than 10 years. The filter screen is made of stainless steel, and different specifications of filter screens can be easily replaced as needed.
