High‑capacity pleated cartridges belong to high‑dirt‑holding folded filter elements, installed in stainless‑steel filter housings and undertaking core security‑filtering work inside ultrafiltration pretreatment systems. Raw‑water sources such as river surface‑water, underground well‑water, industrial circulating water and factory recycled sewage carry silt, rust debris, fine fiber scraps, oily suspended particles and organic colloidal impurities. Without the interception of high‑capacity pleated cartridges, these tiny pollutants will adhere to ultrafiltration‑membrane micropores, trigger irreversible membrane fouling, shorten membrane service life and raise the chemical‑cleaning frequency of ultrafiltration water‑making devices. For that reason, high‑capacity pleated cartridges have become essential regularly‑replaced spare‑parts for all industrial ultrafiltration water‑treatment projects.
Raw‑water firstly eliminates coarse sediment and hard large‑sized particulate pollutants by the upstream liquid filter. After preliminary coarse‑grade filtration, water flows into the filter housing and receives fine‑depth filtration completed by our high‑capacity pleated cartridges. We supply multiple interchangeable filter‑element options for varied ultrafiltration working‑conditions:
‑ For daily‑use ultrafiltration safety filtration: Water Cartridge Filter ALN01‑60B High Flow Industrial Pleated Filter
‑ For thermal‑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‑duty industrial‑water ultrafiltration stations: Cartridge Filter Element for High Flow Applications in Ultrafiltration
Our high‑capacity pleated cartridges consist of multi‑layer widened pleated filter medium, rigid inner supporting skeleton, injection‑molded upper‑and‑lower end‑caps and high‑elasticity EPDM sealing rings. The expanded folded filtering surface greatly enlarges the valid filtering area, bringing powerful dirt‑storage capacity and stable high water‑passing throughput. Compared with ordinary flat‑folded filter cartridges, this high‑capacity series needs fewer installation quantities inside filter housings, saves equipment layout space and cuts later‑period replacement‑maintenance costs. It supports 226‑fin bayonet and flat‑end‑cap mounting ways and matches most international‑standard high‑flow filter housings. Every finished‑product cartridge will go through bubble‑point inspection and hydraulic‑pressure leakage testing before shipment, to guarantee stable matched‑operation with ultrafiltration‑membrane equipment. Our factory provides bulk spot‑goods supply and personalized customization service for non‑standard ultrafiltration‑system parameters.
The complete water‑purification process follows three‑stage progressive filtration: liquid filter coarse filtration → high‑capacity pleated cartridges fine filtration → ultrafiltration‑membrane deep separation. The folded filter medium intercepts suspended contaminants via physical screening, inertial sedimentation and surface adsorption capture.
After coarse screening from the front‑end liquid filter, raw‑water flows inward from the outer pleated layer of the cartridge. Large‑size impurities are trapped on the outer filter‑surface, fine‑grained pollutants are stored inside the folded medium, and purified water flows toward the central water‑collecting pipeline and steadily enters the ultrafiltration membrane module. The ultrafiltration membrane will intercept bacteria, macromolecular organics and ultrafine suspended particles. Benefiting from the huge effective filtering area, high‑capacity pleated cartridges keep low‑stable pressure‑drop under long‑time high‑speed water flow and avoid insufficient water‑supply for continuous ultrafiltration‑water‑making.
Pollutants will pile up gradually on the folded filter‑layer in continuous running and lift the inlet‑outlet pressure‑difference. Once pressure‑difference reaches the 0.25 MPa warning threshold, operators ought to replace the high‑capacity pleated cartridges in time. Blocked cartridges will increase water‑pump operating‑load, reduce ultrafiltration water‑yield and accelerate ultrafiltration‑membrane fouling.
Water filtered by high‑capacity pleated cartridges 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 away pollutants stuck on the ultrafiltration‑membrane surface, slow‑down membrane contamination and prolong the chemical‑cleaning cycle of ultrafiltration machinery.

Q1: What core advantages do high‑capacity pleated cartridges bring to ultrafiltration‑membrane equipment?
A: It adopts multi‑layer widened folded filter‑layer, with large effective filtering area, excellent dirt‑holding capacity and stable big water flux. It intercepts suspended pollutants efficiently, lowers membrane pollution burden and extends ultrafiltration‑membrane service‑life.
Q2: Can‑you customize high‑capacity pleated cartridges to fit my existing ultrafiltration‑system?
A: Yes. Our technical‑staff adjust cartridge‑length, filtration‑precision, filter‑material and end‑cap specifications according to on‑site water‑quality, pipeline‑flow and filter‑housing parameters.
Q3: How long is the standard replacement‑cycle for high‑capacity pleated cartridges?
A: Under stable good‑quality raw‑water, the replacement‑cycle lasts 1‑3 months. High‑turbidity and oily inlet‑water speed‑up cartridge‑clogging and shorten service‑life.
Q4: Why install a liquid filter on the upstream pipeline of high‑capacity pleated cartridges?
A: The front‑mounted liquid filter intercepts gravel, rust chunks and rigid coarse particles, prevents hard particles from scratching the folded filter‑layer, delays cartridge‑blockage and provides dual‑stage protection for downstream ultrafiltration‑membranes.
Q5: Which factors will trigger early‑stage clogging of high‑capacity pleated cartridges?
A: Excessive impurity‑concentration of inlet‑water, upstream liquid‑filter breakdown, long‑term overload‑flow running and improperly‑selected filtration‑precision will lead‑to fast pressure‑difference rise and premature cartridge‑blockage.
Q6: Can multiple high‑capacity pleated cartridges run in parallel on large‑scale industrial ultrafiltration‑machines?
A: Absolutely yes. Multiple cartridges are installed in parallel inside large‑size filter‑housing to supply steady large‑flow qualified feed‑water for heavy‑duty ultrafiltration‑equipment, widely‑adopted within municipal recycled‑water and industrial‑wastewater‑treatment‑projects.
