FiltEdge
FiltEdge’s Automatic Backwash Filter System has a recommended start-up differential pressure of 0.05-0.1MPa, which ensures a balance between Filter Ripening and cleaning efficiency for you.
No.
FiltEdge’s BCM Series Backwash Filter supports Automatic Online Backwash, which allows your filter to take up only a very small portion of the tributary flow during backwash, while over 95% of the remaining area remains in normal filtration, ensuring that your Constant Process Flow is not interrupted.
Our team of professional engineers will provide you with an accurate calculation of Volume of Backwash Water Required based on your system pressure. Based on FiltEdge’s 20 years of experience in the industry, the volume of backwash water required is usually only 0.1% – 0.5% of the total treatment volume.
Our Automatic Backwash Water Filter typically requires a system pressure of at least 0.2-0.3MPa to ensure that the backwash mechanism can generate enough suction to remove contaminants. If the pressure is too low, we can provide you with pressurized model selection support.
FiltEdge, as a professional China Auto Backwash Screen Filter Factory, we offer a wide range of micron ratings from 25μm to 2000μm, and we can provide you with selection suggestions based on your Particle Size Analysis.
FiltEdge’s BCM series has a consumable-free design, and the core Stainless Steel wedge filter does not need to be replaced regularly, which saves you a lot of money on cartridge purchases. The seals (O-rings) only need to be inspected and replaced once every 12-18 months. Depending on your operating conditions, the drain valve and pressure sensor should be inspected every 2-3 years. In short, the BCM series is a very cost-effective Industrial Backwash Filter System.
