Large Flow Water Treatment Filter Cartridge | High Throughput Pleated Industrial Cartridge

Large Flow Water Treatment Filter Cartridge | High Throughput Pleated Industrial Cartridge

Large Flow Water Treatment Filter Cartridge is a large‑diameter pleated filtration consumable designed for modern industrial water‑treatment projects. Featuring expanded pleated filtration area, this large flow water treatment filter cartridge achieves high throughput with low pressure drop, greatly reducing the quantity of cartridges and filter housings required for high‑capacity water systems. Adopting adhesive‑free thermal‑fusion bonding, it delivers good chemical stability and prevents secondary contamination of treated water. Our interchangeable large flow water treatment filter cartridge can be directly fitted into most mainstream high‑flow filter housings. Plenty of water‑treatment projects adopt RTM41HF050E filter cartridge and HFU660CAS010JUW filter element together with large flow water treatment filter cartridge for multi‑stage purification in power, chemical, food‑beverage and municipal water sectors.

Product Overview

Large Flow Water Treatment Filter Cartridge belongs to heavy‑duty pleated filter series for liquid phase water treatment. Compared with conventional standard‑size filter cartridges, it adopts large‑diameter radial pleated structure and multi‑layer gradient filter media, which maximizes effective filtration area and realizes large‑flow operation without sacrificing filtration accuracy. Most versions are designed as single open‑end with integrated lifting handle for quick and safe replacement on site. Multiple filter media options including polypropylene and composite materials are available, covering micron grades from 1 μm to 100 μm, satisfying pre‑filtration and fine polishing requirements for different industrial water quality.

Large Flow Water Treatment Filter Cartridge undertakes core pre‑filtration and equipment protection tasks in RO, NF and UF water treatment systems. It effectively intercepts sediment, suspended solids, colloids and granular pollutants in raw water, reduces membrane fouling probability and extends service life of membrane modules and downstream precision equipment. Although imported original large flow water treatment filter cartridge shows stable performance, global buyers are faced with high purchase cost and long delivery cycle. As a professional filter manufacturer, our replacement large flow water treatment filter cartridge strictly controls dimensional tolerance and particle retention efficiency. Each batch passes bubble‑point test and pressure‑tightness inspection before shipment for worldwide system integrators and end‑users.

Core specifications of Large Flow Water Treatment Filter Cartridge: Filter media: PP / composite gradient pleated fiber; micron ratings:1‑100 μm; outer diameter:6‑6.75 inch; available lengths:20/40/60/80 inch; end type: single open‑end radial pleated; flow direction: inside‑to‑outside / outside‑to‑inside optional; adhesive‑free thermal‑fusion welding; O‑ring options: silicone, EPR, NBR, FKM; max continuous operating temperature:60‑71℃; recommended replacement differential pressure:2.4 bar; drop‑in compatible with mainstream large‑flow filter housings.

Replacement Large Flow Water Treatment Filter Cartridge supports direct installation without modifying filter housings. With large throughput, big dirt‑holding capacity and wide chemical compatibility, it is an ideal filter consumable for large‑scale industrial and municipal water‑treatment systems.

Filtration Working Principle

Large Flow Water Treatment Filter Cartridge follows surface‑depth combined gradient filtration principle. Under system operating pressure, raw water evenly flows through multi‑layer radial‑pleated filter media. Large‑size impurities such as sediment and flocs are trapped on outer pleated layers, while fine suspended particles and colloids are deeply intercepted by inner gradient fiber layers. Optimized pleat structure prevents media deformation and collapsing under long‑term large‑flow operation and keeps stable low‑pressure‑drop performance. Thermal‑fusion integral structure avoids glue dissolution and secondary water pollution. When inlet‑outlet differential pressure rises to 2.4 bar, large flow water treatment filter cartridge reaches dirt‑holding saturation and needs timely replacement to ensure stable effluent‑water quality.

Core Competitive Advantages

Large‑Diameter Pleated Design: 

Expands effective filtration area, realizes large flow operation and reduces total cartridge number for water‑treatment systems.

Multi‑media Optional: 

Polypropylene and composite media for different water quality and chemical compatibility requirements.

High Dirt‑holding Capacity: 

Multi‑layer gradient‑fiber structure improves pollutant storage capacity, extends service cycle and cuts system downtime loss.

Adhesive‑Free Thermal‑Fusion Process: 

No chemical glue, prevents secondary contamination, suitable for food‑beverage and drinking‑water related projects.

Integrated Lifting‑Handle: 

Convenient pull‑out operation, lowers direct contact risk with contaminated filter media during replacement.

Precise Interchange & Strict Quality Inspection: 

Standard dimensional tolerance fits mainstream filter housings; bubble‑point and pressure‑tightness tests guarantee stable filtration performance.

FAQ

Q1: What is Large Flow Water Treatment Filter Cartridge used for?

A1: It is large‑diameter pleated filter consumable for large‑scale water‑treatment, mainly used for RO pre‑security filtration to remove sediment, suspended solids and colloids and protect downstream membrane modules.

Q2: What benefits does large flow filter cartridge bring?

A2: It provides large throughput, fewer cartridge requirements, smaller housing investment, large dirt‑holding capacity and convenient field maintenance.

Q3: When shall we replace large flow water treatment filter cartridge?

A3: Replace when inlet‑outlet differential pressure reaches 2.4 bar. High‑turbidity raw water will shorten its service life accordingly.

Q4: Can Large Flow Water Treatment Filter Cartridge be cleaned and reused?

A4: It is disposable pleated filter consumable. Fine impurities penetrate deep into filter media; backwashing cannot restore full filtration performance, disposable replacement is recommended.

Q5: What information do you need for quotation?

A5: Please provide original part number, or specify cartridge length, micron rating, flow direction, O‑ring material and working‑condition parameters.
