Many factory maintenance technicians believe that frequent clogging of security filter cartridges is simply due to high levels of impurities in the water or poor filter quality. Having handled over 200 water filtration systems in ten years, I can confidently say that 75% of clogging issues have absolutely nothing to do with the filter cartridge itself.
Security Filter
I. Equipment Pipeline Corrosion and Sludge Accumulation Clogging
Most factories neglect pipeline maintenance. Rust and biological sludge in old pipes are the hidden culprits behind clogging. Last year, a customer in a water purification project experienced a newly replaced filter cartridge clogging just two days later. The influent water quality tested normal, and the root cause was completely elusive. Upon disassembling the pipeline, they discovered a 0.3mm thick layer of biological sludge adhering to the inner wall of the pipes. This sludge continued to flake off after being impacted by water flow, clogging the micropores of the filter cartridge. The core techniques for corrosion and rust prevention maintenance of well water filtration equipment are regular pipe flushing, checking for rust spots, and timely replacement of aging pipe fittings.
II. Improper Operating Parameter Settings Leading to Rapid Clogging
Excessive inlet flow and unstable water pressure can significantly shorten filter cartridge lifespan, a point many people overlook. I encountered a chemical company where the equipment's rated flow rate was 5m³/h, but employees were consistently running it at 8m³/h, exceeding the load. The high-speed water flow forcibly carried fine impurities into the deep micropores of the filter cartridge, rendering regular flushing completely ineffective, and the filter cartridge became completely unusable within 3-5 days. After adjusting back to the standard flow rate, the frequency of filter cartridge clogging decreased by 80%.
