Seawater Sulfate Nanofiltration (NF) Membrane

SWSR - SeaWater Sulfate Reducing Nanofiltration (NF) Membrane

The SWSR is a Nanofiltration membrane element portfolio developed for seawater sulfate removal. It is built on SUEZ's robust DK membrane platform, which has been used for over 30 years in some of the most challenging applications. The SWSR NF membrane features a 300 Dalton Molecular Weight cut-off and is an absolute barrier for any suspended matter including particles, colloidal silica, and bacterial matters.

SWSR Nanofiltration Membrane Features:

  • Prevents strontium and barium sulfate scale in injection wells
  • Better well souring mitigation by reducing the incoming sulfate
  • Optimized for use in seawater while providing superior hydrodynamics, which result in longer membrane life
  • Unique and long-proven SUEZ 3-layer membrane structure that minimizes surface roughness and adherence
  • Available in a 440 sq. ft. version to maximize membrane area for new systems while minimizing footprint
  • Superior hardness and sulfate removal properties
  • Chemical compatibility with cleaners currently used in the industry
  • Innovative spacer design combined with 3-layer membrane allows improved fouling resistance when retrofitting existing installations

Dairy DK

Dairy DK, or dairy processing, NF membrane elements are used in food-related processes requiring stringent sanitary procedures. Typical applications include deacidification and demineralization of whey or UF permeate and lactose desalting. 

 

Dairy DL

Dairy DL, or dairy processing, NF membrane elements are used in food-related processes requiring stringent sanitary procedures. Typical applications include deacidification and demineralization of whey or UF permeate and lactose desalting. 

 

DK

DK high rejection NF elements generally are used for dye removal/concentration, metals recovery, sodium chloride diafiltration, sulfate removal, and bio-chemical purification. 

 

DL

 

The DL series comprises industrial high flow NF membrane elements. Typical applications include dye removal/concentration, sodium chloride diafiltration, metals recovery, and bio-chemical purification.  

 

Duracon

The Duracon NF membrane elements are engineered for use in food-related processes requiring stringent sanitary procedures and customarily are used for processing sugar solutions in food-related processes. Typical applications for the Duracon NF1 series include demineralization, deacidification, and sugar concentration. Typical applications for the Duracon NF2 series include mono-saccharides purification

 

HL Series

The HL series of NF membrane elements have a molecular weight cutoff of 150-300. Typical applications are water softening, partial water softening in municipal and industrial markets, color removal, and reduction of THM formation potential. 

 

MUNI NF Series

 

The Muni NF provides a cost effective and low pressure nanofiltration alternative to standard reverse osmosis treatment. Typical application is municipal drinking water plants. Performance is characterized by hardness reduction, color removal, and organic pollutants reduction (such as the precursors to THM). 

 

Seawater Sulfate Removal (SWSR) 

The SWSR NF-series membrane features a 300 Dalton molecular weight cut-off and is an absolute barrier for any suspended matter including particles, colloidal silica, and bacterial matters. The SWSR membrane is recognized for its low fouling properties and is designed to produce consistently low sulfate water for injection. 

 

Vinopro

Vinopro nanofiltration membrane elements are characterized by an approximate molecular weight cutoff of 150-300 Dalton for uncharged organic molecules. Typically used for grape sugars concentration, oak extract fractionation, alcohol and acidity reduction, and wine adjustment.
