Fulflo Mega Flow Plus Large Diameter Pleated Filter Cartridge for UF Pretreatment

1. Product Introduction of Fulflo Mega Flow Plus Large Diameter Pleated Filter Cartridge

Fulflo Mega Flow Plus Large Diameter Pleated Filter Cartridge is a large‑diameter, high‑throughput pleated filter element designed as a premium substitute for mainstream large‑flow filter cartridges inside ultrafiltration pretreatment systems. Industrial raw‑water resources such as surface water, underground well‑water and recycled factory wastewater carry sediment, rust debris, textile fibers and organic colloidal pollutants. Without the interception of this large‑diameter pleated cartridge, fine contaminants will scratch and block ultrafiltration‑membrane holes, trigger irreversible membrane fouling, shorten membrane service life and raise the chemical‑cleaning frequency of your ultrafiltration plant. For‑this reason, large‑diameter high‑flow pleated cartridges have become essential security‑filtration parts for modern industrial ultrafiltration projects.

Raw‑water first gets rid of coarse sediment and rigid large‑particulate pollutants from the upstream liquid filter. After coarse filtration, water flows into the stainless‑steel filter housing and is deeply treated by our Fulflo Mega Flow Plus cartridge. We supply multiple interchangeable filter elements for different ultrafiltration working‑conditions:

• For general‑purpose ultrafiltration security filtration: Pleated Security Filter Element for Industrial Ultrafiltration

• For power‑plant condensed‑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‑treatment ultrafiltration stations: Cartridge Filter Element for High‑Flow Applications in Ultrafiltration

This replacement‑style Fulflo Mega Flow Plus cartridge consists of multi‑layer folded filter medium, reinforced inner support skeleton, injection‑molded upper‑and‑lower end‑caps and high‑elasticity EPDM sealing rings. Common filter‑medium choices include polypropylene, glass‑fiber and PTFE. The enlarged‑diameter body maximizes pleat quantity and effective filtration surface area. It adopts the widely‑used 226‑fin bayonet interface and fits most international standard high‑flow filter housings. Every finished‑product cartridge will go‑through bubble‑point inspection and hydraulic‑pressure leakage testing before shipment, ensuring stable cooperation with ultrafiltration membrane equipment. Our factory supports bulk spot supply and personalized customization for non‑standard ultrafiltration‑system requirements.

2. Working Principle: Collaborative Filtration With Ultrafiltration Equipment

The complete water‑purification workflow adopts three‑stage progressive filtration: liquid filter coarse filtration → Fulflo Mega Flow Plus large‑diameter pleated cartridge fine filtration → ultrafiltration‑membrane deep separation. The folded filter‑medium captures suspended particles via physical interception, inertial sedimentation and surface‑adsorption effects.

2.1 Long‑Time Stable Filtration Operation

After coarse‑screening by the front‑end liquid filter, raw‑water flows into the filter housing and permeates from the outer pleated layer inward to the central water‑collecting pipe. Big‑size impurities are trapped on the cartridge outer‑surface, while tiny colloids and organic particles are held inside the folded filter‑layer. Purified water converges inside the central pipeline and flows steadily into ultrafiltration equipment to remove bacteria, macromolecular organics and ultra‑fine suspended particles. The large‑diameter folded‑structure brings far‑larger effective filtration‑area than ordinary small‑size filter cartridges, keeping low‑stable pressure‑drop under long‑time high‑flow running and preventing water‑supply shortage for continuous ultrafiltration water‑making.

2.2 Differential‑Pressure Reminder for Cartridge Replacement

Pollutants will accumulate gradually on folded filter‑media during continuous operation and lift the inlet‑outlet pressure‑difference. Once the pressure‑difference hits 0.25 MPa warning value, operators need to replace the Fulflo Mega Flow Plus cartridge promptly. Clogged filter cartridges will increase water‑pump load, cut ultrafiltration water‑yield and speed‑up membrane fouling.

2.3 Matching the Ultrafiltration Back‑Washing System

Water filtered by the large‑diameter pleated cartridge can serve as the back‑wash water‑source of ultrafiltration membrane modules. When mixed with compressed air, it forms gas‑water mixed cleaning‑fluid to flush pollutants sticking on the ultrafiltration‑membrane surface, slow‑down membrane contamination and prolong the chemical‑cleaning cycle of ultrafiltration devices.
