Durable Hi Flow Filter Cartridge For Industrial Ultrafiltration Water Treatment

1. Product Introduction of Hi Flow Filter Cartridge

The hi flow filter cartridge is a high‑throughput folded filter element, widely installed inside filter housings and regarded as the vital security‑filtration spare‑part of ultrafiltration pretreatment systems. Raw water sourced from river surface‑water, underground well‑water, industrial circulating water and factory reclaimed‑water carries silt, rust debris, fine fiber waste, oily particles and organic colloidal pollutants. Without the interception from hi‑flow filter cartridges, tiny contaminants will cling to ultrafiltration‑membrane micropores, trigger serious membrane fouling, shorten membrane service life and raise the frequency of chemical cleaning for ultrafiltration water‑making devices. Consequently, high‑flow filter cartridges have turned into essential consumables for all kinds of industrial ultrafiltration water‑treatment projects.

Raw‑water firstly removes coarse sediment and hard large‑size particulate pollutants through the upstream liquid filter. After preliminary coarse filtration, water flows into the stainless‑steel filter housing and gets fine filtration handled by our hi flow filter cartridge. We supply multiple interchangeable filter elements suitable for different ultrafiltration working‑conditions:

• For daily‑use ultrafiltration security filtration: Pleated Security Filter Element for Industrial Ultrafiltration

• For power‑plant condensate 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 hi flow filter cartridge is composed of broad‑width folded filter medium, rigid inner supporting skeleton, injection‑molded upper‑and‑lower end‑caps and high‑elasticity EPDM sealing rings. The expanded pleated filter‑layer greatly increases the effective filtering area, bringing about large water‑passing capacity and strong dirt‑storage performance. Compared with ordinary small‑size common filter cartridges, our high‑flow cartridge demands fewer installation quantities inside the filter housing, cuts equipment space occupation and lowers the later‑stage replacement‑maintenance cost. It supports 226‑fin bayonet and flat‑end‑cap installation, compatible with most international‑standard high‑flow filter housings. Every finished‑product will go through bubble‑point inspection and hydraulic‑pressure leakage testing before shipment, guaranteeing stable matched‑operation with ultrafiltration‑membrane equipment. 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 complete water‑purification workflow adopts three‑stage progressive filtration: liquid filter coarse filtration → hi flow filter cartridge fine filtration → ultrafiltration‑membrane deep separation. The folded filter medium intercepts suspended contaminants by physical sieving, inertial sedimentation and adsorption capture effects.

2.1 Long‑Time Stable Filtration Operation

After coarse screening of the front‑end liquid filter, raw‑water enters the filter housing and flows through the outer folded filter‑layer. Large‑size impurities are trapped on the outer surface, while fine‑grained pollutants are captured inside the folded medium. Clean water flows toward the central water‑collecting pipeline and steadily enters the ultrafiltration unit to remove bacteria, macromolecular organics and ultrafine suspended particles. Thanks to the huge effective filter area, the hi‑flow filter cartridge maintains low‑stable pressure‑drop during 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 pile‑up 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 hi flow filter cartridge promptly. Clogged cartridges will increase water‑pump running‑load, reduce ultrafiltration water‑yield and accelerate ultrafiltration‑membrane fouling.

2.3 Cooperation With Ultrafiltration Back‑Washing System

Water filtered by the hi‑flow filter cartridge can serve as the back‑flush water‑source of ultrafiltration membrane modules. After mixing with compressed air, it forms gas‑water mixed cleaning‑liquid to wash away surface‑stuck pollutants on ultrafiltration membranes, slow‑down membrane contamination and extend the chemical‑cleaning cycle of ultrafiltration machinery.
