The high flow filter cartridge is a pleated large‑flux filter element installed inside stainless‑steel filter housing, undertaking fine pretreatment before raw‑water enters ultrafiltration separation equipment.
Industrial raw water, circulating cooling water, process‑water and recycled wastewater commonly carry silt, metal particles, oily sludge and tiny colloidal contaminants. Without the blocking of high‑flow filter cartridge, hard granular debris will scratch ultrafiltration membrane surface, bring serious membrane fouling, raise chemical‑cleaning frequency and greatly shorten membrane service life. Our pleated high‑flow cartridge adopts multi‑layer polypropylene folded material, featuring large pollution‑holding capacity, stable high‑speed water throughput and excellent acid‑alkali resistance, better than ordinary small‑flow filter elements.
Raw‑water firstly removes rust chunks and large sediment by the upstream liquid filter. After coarse filtration, water flows into filter housing for deep purification. Multiple optional cartridge types for different working‑conditions are listed below：
‑ General‑purpose ultrafiltration safety filtration：AQUALINE ALN01‑60B High Flow Pleated Water Cartridge Filter
‑ Import‑model replacement cartridge：EQUIVALENT ALN01‑60B High Flow Pleated Water Filter Cartridge
‑ Steam‑power‑plant condensed‑water recycling：Condensed Water Filter Cartridge for Industrial Ultrafiltration
‑ Seawater and high‑salinity water projects：Dow Membrane Filters Type SW30HRLE‑400 High‑Flow Cartridge
Each high‑flow filter cartridge consists of multi‑layer pleated filter fabric, rigid inner support skeleton, wear‑resistant injection‑molded end‑caps and corrosion‑proof EPDM sealing rings. Two mainstream installation types, the 226‑fin bayonet and flat open‑end cap, fit most international‑standard filter housings. Every finished‑item will pass bubble‑point inspection, air‑tightness test and acid‑alkali soaking test before shipment. Our factory supports bulk supply and non‑standard customization according to real‑site water‑quality data and ultrafiltration system parameters.
The whole water‑purification workflow adopts three‑level progressive filtration: liquid filter coarse filtration → high flow filter cartridge fine physical screening → ultrafiltration‑membrane deep separation. The folded filter medium traps varied‑size particles by physical sieving, inertial sedimentation and surface adsorption.
After coarse impurity removal by upstream liquid filter, raw‑water flows inward from the outer folded layer of the cartridge. Large suspended waste stays on the outer surface, fine particles and colloids are blocked by multi‑layer dense filter cloth, and purified water flows through the central pipeline and enters ultrafiltration‑membrane module.
Ultrafiltration membranes will intercept macromolecular organics, bacteria and micro‑fine pollutants. Thanks to the expanded folded filtering area, the high‑flow cartridge keeps low‑pressure drop under long‑time high‑speed water flow and provides stable feed‑water for non‑stop‑running ultrafiltration machines.
Pollutants continuously accumulate on the folded filter layer during operation and lift inlet‑outlet pressure‑difference. Operators need to replace the cartridge once pressure‑difference hits 0.25 MPa. Clogged cartridges will increase pump load, reduce ultrafiltration water‑yield and speed‑up membrane abrasion.
Water treated by high‑flow filter cartridge acts as back‑flushing water source for ultrafiltration‑membrane assemblies. Mixed with compressed air, gas‑water flow washes away surface contaminants, slows fouling and lengthens the chemical‑cleaning cycle of ultrafiltration equipment.

Q1: What benefits will high flow filter cartridge bring to ultrafiltration‑membrane equipment?
A: It owns enlarged folded filtering surface and strong dirt‑holding capacity, intercepts suspended particles, oil sludge and colloidal pollutants, reduce membrane fouling, cut chemical‑cleaning times and extend ultrafiltration‑membrane working‑life.
Q2: Can you customize high‑flow filter cartridge for my existing ultrafiltration‑water‑treatment system?
A: Yes. Our technicians adjust cartridge length, filtering precision, filter‑medium and end‑cap style based on on‑site water‑quality, pipeline flow and filter‑housing parameters.
Q3: What is the standard replacement cycle for high flow filter cartridge?
A: Its normal service‑life lasts 1‑3 months under low‑polluted inlet‑water. Heavy‑polluted oily sewage and seawater will speed‑up clogging and shorten usage cycle.
Q4: Why install a liquid filter on the upstream pipeline of high‑flow filter cartridge?
A: The upstream liquid filter traps large‑size silt, rust lumps and hard coarse particles, prevent rigid debris from scratching folded filter cloth, delay clogging and realize dual‑stage protection for ultrafiltration‑membranes.
Q5: What reasons will cause early‑stage blockage on the high‑flow filter cartridge?
A: Excessive pollutant concentration of inlet‑water, upstream liquid‑filter failure, long‑time over‑rated‑flow running and improperly‑selected filter material will lead to fast‑rising pressure‑difference and premature cartridge clogging.
Q6: Can multiple high‑flow filter cartridges adopt parallel installation on large‑scale ultrafiltration‑water‑treatment machines?
A: Parallel installation is fully supported. Multiple cartridges work together in big filter housing and provide steady large‑flux pretreated water for heavy‑duty industrial ultrafiltration facilities.
