Fine Filtration That Protects Expensive Downstream Equipment

Fine solids, colloids and process contaminants can raise differential pressure, shorten membrane life, increase cartridge change-outs and create unstable water quality. The right cartridge filtration system reduces risk before it reaches the RO skid, UF membrane, EDI module or final polishing loop.
Suspended Solids
Reduce dirt, sand, rust, silt and particulates that plug filters, valves, nozzles and heat-transfer surfaces.
Turbidity Control
Improve feedwater clarity before process water, cooling water, boiler makeup, RO pretreatment or reuse systems.
Chlorine & Organics
Use activated carbon filters to reduce chlorine and dissolved organics before RO membranes or ion exchange resin.
RO / UF Protection
Pre-filter housings for membrane systems
Standard & High-Flow
Single, multi-round and large-format vessels
Industrial Materials
SS304, SS316L, FRP and lined options

Cartridge Filtration Systems and Filter Cartridge Vessels Explained

1

Raw Water

Well, municipal, surface, seawater, reuse or process return water.

2

Media / UF

Optional bulk solids and turbidity reduction before cartridge filtration.

3

Cartridge Housing

Fine filtration before RO, UF, ion exchange, EDI or final polishing.

4

Core Treatment

RO membranes, UF systems, EDI, softeners or ion exchange units.

5

Polishing / Use

High-purity loop, process water, cooling, boiler or product water.
