Membrane Filtration


Nalco Pretreatment Solutions (PTS) incorporates membrane filtration housings and membrane filtration cartridges as part of a well-designed water treatment system.  The choices of membrane filter construction, membrane housing and membrane filtration manufacturers are nearly limitless. 

Depending upon your inlet water quality and the water quality you require, combinations of micron filtration, sub-micron filtration, ultrafiltration and/or nanofiltration will be required.  The membrane can be manufactured from polypropylene, polysulfone, cotton, cellulose, nylon and more.  The membrane can be pleated, melt blown and string wound.  The membrane is made into a replaceable cartridge with a variety of end connections, gasket materials and lengths, depending upon the application and flow requirements. 

Membrane filter housings are available in a wide variety of materials including 316 stainless steel, PVDF, polypropylene and other metallic and non-metallic choices. Filter housings can have threaded, flanged and sanitary connections.  Internal and external construction can affect the ease of installation and maintenance.  Also, correct housing construction will improve overall water quality out of the membrane filtration process.

Nalco PTS offers onsite preventive maintenance to monitor and maintain these units in peak performance and reduce the workload of your team.
