Pure Aqua, Inc. manufactures a full line of Ultra filtration (UF) systems. UF is a pressure driven membrane separation process that removes suspended or particulate matter (including colloids & silt) from water. The solution is far more reliable than a conventional multimedia filter that removes approximately 10-20+ micron or larger matter where a UF membrane pore size ranges from 0.01 to 0.10 micron. In addition to superior turbidity removal, UF membranes efficiently remove bacteria and most viruses.
The ability of UF systems to remove bacteria and most viruses makes the technology ideal for grey water recycling and/or tertiary treatment of sewage. The membrane provides an absolute barrier, protecting the public from pathogens. Furthermore, disinfection requirements are greatly reduced as dosing rates of chlorine; UV and/or ozone are much lower since there are essentially no suspended solids left in the filtered water. Note turbid water allows for pathogens to hide, as such, higher dosing rates are required to ensure proper disinfection.
Another great application for UF is RO pre-treatment, again the membrane essentially removes 100% of suspended solids; this is critical as RO membranes are designed to remove only dissolved solids. Colloidal fouling is a large problem with RO systems and leads to irreversible damage and shortened membrane life. In demanding pre-treatment situations, UF membranes can replace clarifiers and multi-media filters as the membrane can handle up to 100 ppm total suspended solids; a conventional sand filter would be quickly overloaded, requiring clarification prior to sand filtration. Furthermore, the latter is dependent on settling rates and chemical addition (i.e. coagulants/polymers). UF filters provide consistent and guaranteed product water.
