Ultrafiltration employs the use of a porous fiber that filters out most unwanted constituents in feed water. These membranes have pore sizes in the range of 0.01 to 0.1 microns. There are several types of ultrafiltration membranes such as hollow fiber membranes and spiral wound membranes. As an example, a spiral-wound membrane consists of flat sheets wrapped in a spiral configuration similar to a reverse osmosis membrane. The pores in a hollow fiber membrane or spiral wound membrane should be consistently on the order of 0.1 to 0.2 µm in size.Ultrafiltration provides the end user with the ability to consistently and efficiently remove suspended solids, bacteria, yeast, some viruses, and harmful biological contaminants such as Giardia Lamblia and Cryptosporidium from feed water. Typical fiber material is dependant on the manufacturer and application but can be commonly found in PVDF (Polyvinylidenefluoride), Polyacrylonitrile, or Polyethylene. Material choice can be dictated upon also considering the Molecular Weight Cutoff of the membrane material. A membrane containing a smaller MWCO provides better overall filtration.

Flocon Industries Ultrafiltration Systems are designed for removal of suspended solids including bacteria, endotoxins and high molecular weight molecules. This level of filtration offers many advantages, including reduced fouling of any downstream RO membranes and lower endotoxin burden on downstream equipment.The membrane filters can be provided individually or as part of a total water treatment solution. The control system for the membrane filters can be dedicated to the filter system or part of a total water system. Hollow-fiber membrane construction allows reverse flow backwash cycles to remove the accumulation of filtered solids.
