Premium High Capacity Filter Cartridge for Industrial Ultrafiltration Pretreatment

1. Product Introduction of High Capacity Filter Cartridge

The high‑capacity filter cartridge is a high‑dirt‑holding pleated filter element, installed inside stainless‑steel filter housings and acting as the core security‑protection component for ultrafiltration pretreatment. Raw‑water resources including river surface‑water, underground well‑water, industrial circulating water and factory recycling sewage carry silt, rust particles, fine textile fiber waste, oily suspended matter and organic colloidal contaminants. Without the interception of high‑capacity filter cartridges, these tiny pollutants will stick onto ultrafiltration‑membrane micropores, bring irreversible membrane fouling, shorten membrane service life and raise the chemical‑cleaning frequency of ultrafiltration‑water‑making equipment. Hence, high‑capacity filter cartridges are indispensable regular‑replacement spare‑parts for all kinds of industrial ultrafiltration water‑treatment projects.

Raw‑water first removes coarse sediment and hard large‑size particulate contaminants through the upstream liquid filter. After preliminary coarse filtration, water flows into the filter housing and receives fine‑depth filtration handled by our high‑capacity filter cartridge. We supply multiple interchangeable filter‑element options adapting to diverse ultrafiltration working‑conditions:

• For common‑use ultrafiltration security filtration: Water Cartridge Filter ALN01‑60B High Flow Industrial Pleated Filter

• For power‑plant condensate‑water ultrafiltration projects: Condensed Water Filter Element for Industrial Ultrafiltration

• For seawater‑desalination ultrafiltration pretreatment: Dow Membrane Filters Type SW30HRLE‑400 High Flow Cartridge

• For heavy‑load industrial‑water ultrafiltration stations: Cartridge Filter Element for High Flow Applications in Ultrafiltration

Our high‑capacity filter cartridge consists of multi‑layer wide pleated filter medium, rigid inner supporting skeleton, injection‑formed upper‑and‑lower end‑caps and high‑elasticity EPDM sealing rings. The expanded folded‑filter surface greatly enlarges the effective filtering area, achieving excellent dirt‑storage volume and stable high water throughput. Compared with ordinary common filter cartridges, this high‑capacity model requires fewer installation units inside filter housings, saves installation space and reduces later‑stage replacement‑maintenance expenses. It supports 226‑fin bayonet and flat‑end‑cap installation modes and fits most international‑standard high‑flow filter housings. Every finished cartridge will complete bubble‑point inspection and hydraulic‑pressure leakage testing before shipment, ensuring stable matched‑operation with ultrafiltration‑membrane devices. Our factory provides bulk spot supply and personalized customization service for non‑standard ultrafiltration‑system parameters.

2. Working Principle: Collaborative Filtration With Ultrafiltration Equipment

The full water‑purification workflow adopts three‑stage progressive filtration: liquid filter coarse filtration → high‑capacity filter cartridge fine filtration → ultrafiltration‑membrane deep separation. The folded filter medium intercepts suspended contaminants by physical sieving, inertial sedimentation and surface adsorption capture.

2.1 Long‑Time Stable Filtration Operation

After coarse screening of the front‑end liquid filter, raw‑water enters the filter housing and flows inward through the outer pleated filter‑layer. Large‑sized impurities are trapped on the outer surface, fine pollutants are stored inside the folded medium, and purified water flows toward the central water‑collecting pipeline and steadily enters the ultrafiltration module. The ultrafiltration membrane will intercept bacteria, macromolecular organic substances and ultrafine suspended particles. Thanks to the huge effective filtering area, the high‑capacity filter cartridge maintains low‑stable pressure‑drop under long‑time high‑speed water flow and avoids water‑supply shortage for continuous ultrafiltration‑water‑making.

2.2 Differential‑Pressure Reminder For Cartridge Replacement

Pollutants will accumulate gradually on the folded filter‑layer in continuous operation and lift the inlet‑outlet pressure‑difference. Once pressure‑difference hits the 0.25 MPa warning value, operators need to replace the high‑capacity filter cartridge promptly. Clogged cartridges will increase water‑pump operating‑load, reduce ultrafiltration water‑yield and accelerate ultrafiltration‑membrane fouling.

2.3 Cooperation With Ultrafiltration Back‑Washing System

Water filtered by the high‑capacity filter cartridge can serve as the back‑flush water‑source of ultrafiltration membrane assemblies. After mixing with compressed air, it forms gas‑water mixed cleaning‑liquid to wash pollutants adhering to the ultrafiltration‑membrane surface, slow‑down membrane contamination and extend the chemical‑cleaning cycle of ultrafiltration machinery.
