Ultrafiltration (also called Nanofiltration) is a membrane filtration process similar to Reverse Osmosis, using hydrostatic pressure to force water through a semi-permeable membrane.
Crystal Quest's ultrafiltration (UF) water treatment systems are specifically designed to produce drinking water that meets today’s stringent standards. The systems use uniquely designed filtration modules in a hollow fiber configuration to remove the following contaminants from surface and ground water sources: Suspended solids/turbidity, Viruses, Bacteria, Cysts and oocysts, Iron and manganese, Arsenic, Organics.

The Crystal Quest Ultrafiltration/Nanofiltration System is a free-standing design that requires simple installation.
The Crystal Quest Ultrafiltration/Nanofiltration system is used to remove essentially all colloidal particles (0.01 to 1.0 microns) from water and some of the largest dissolved contaminants. The pore size in a Crystal Quest Hollow Fiber UF membrane is mainly responsible for determining the type and size of contaminants removed. In general, membrane pores range in size from 0.005 to 0.1 micron.
UF membrane manufacturers such as Scientific World Products, classify each UF product as having a specific molecular weight cutoff (MWC), which is a rough measurement of the size of contaminants removed by a given UF membrane. A 100,000 MWC UF membrane means that when water containing a given standard compound with a molecular weight of around 100,000 daltons is fed to the UF unit, nearly all of the compound will not pass through the membrane.
Substances with a molecular weight of 100,000 daltons have a size of about 0.05 microns to about 0.08 microns in diameter. UF membranes are used where essentially all colloidal particles (including most pathogenic organisms) must be removed, but most of the dissolved solids may pass through the membrane without causing problems downstream or in the finished water. The Crystal Quest Ultrafiltration/Nanofiltration system will remove most turbidity from water.
Crystal Quest's hollow fiber membranes are highly permeable, resulting in high water production rates. Each hollow fiber module provides high active surface area of up to 538 ft2. Our dedication to a simplified process and control design has produced a family of systems that are characterized by:
