Dowac Systems offers effective ultra filtration systems for treating heavy surface water.  Our systems ultrafulterationdesigned by using advanced technology with the purpose of removing micro bacterial counts.

Ultrafiltration (UF) is used to remove essentially all colloidal particles (0.001 to 1.0 microns) from water and some of the largest dissolved contaminants. The pore size in a UF membrane is mainly responsible for determining the type and size of contaminants removed.

Ultra filtration treated water can be sent for reverse osmosis and recycled or further taken for portable application. Using Ultrafiltration systems to recycle water can yield zero discharge capabilities.

Ultra-filtration results in considerable savings in terms of pre-treatment and increased RO availability factor.

The primary advantages of low-pressure UF membrane process are:

  • No need for chemicals (coagulants, flocculates, disinfectants, pH adjustment);
  • Size-exclusion filtration as opposed to media depth filtration;
  • Good and constant quality of the treated water in terms of particle and microbial removal;
  • Process and plant compactness; and
  • Simple automation

Ultrafiltration is used in:

  • Laboratory grade water purification
  • Wastewater treatment
  • Drinking water treatment
  • Paint Recovery in the automotive industry
  • Desalting and solvent-exchange of proteins
  • Dialysis and other blood treatments
