Filtration Systems
Filtration systems remove particulate, microbial and dissolved contaminants from process liquids and gases to protect product quality and equipment. This directory lists specialist manufacturers and suppliers of depth filters, cartridge filters, membrane filters and ultrafiltration systems for water and wastewater treatment, chemicals, food and beverage, pharmaceutical and oil and gas processing.
Each company listed below is profiled with its product range, markets served and contact details.

Depth filters
Depth Filters
Depth filters capture contaminants throughout the thickness of the filter medium rather than only at its surface, which gives them a high dirt-holding capacity and a long service life. Built from graded layers of cellulose, glass fibre, polypropylene or sintered material, they are used to clarify viscous or heavily loaded liquids and to protect finer membrane filters downstream in chemical, food and beverage, pharmaceutical and water treatment processes. Find global manufacturers of depth filters in our Equipment Guide.

Cartridge filters
Cartridge Filters
Cartridge filters hold the filter medium in a replaceable cylindrical element that sits inside a housing, so the element can be swapped out without disturbing the pipework. Pleated, wound and melt-blown constructions cover micron ratings from coarse clarification down to sub-micron polishing, in polypropylene, polyester, stainless steel and PTFE. They are the workhorse of point-of-use filtration in water treatment, chemicals, food and beverage and pharmaceutical processing.

Membrane filters
Membrane Filters
Membrane filters separate at the surface of a thin polymeric or ceramic film with a defined pore size, so they retain particles, bacteria or dissolved molecules by size exclusion rather than by depth capture. Microfiltration, ultrafiltration, nanofiltration and reverse osmosis each work at a finer cut-off, and are supplied as flat sheet, spiral wound, hollow fibre or tubular modules for water treatment, dairy, biotechnology and pharmaceutical processing.

Ultrafiltration systems
Ultrafiltration Systems
Ultrafiltration systems drive liquid through a membrane with a pore size of roughly 0.01 to 0.1 micron, retaining suspended solids, bacteria, viruses and high molecular weight compounds while dissolved salts pass through. Because they work at modest pressure and produce a consistent permeate quality, they are used to pre-treat feed for reverse osmosis, to recover process water, and to concentrate proteins and other products in dairy, food and biotechnology plants.
