Complete Treatment with the ICS-BK Bacteria Filter is a simple single step process.

The Cascadian ICS-B Bacteria Filter Systems are designed to provide >99% reduction for bacteria, virus and microspheres from the water. The bacteria filter kills and traps the bacteria, they are removed from the water stream. Removing the target from the water stream is very different than ultraviolet light disinfection systems which prevent them from reproducing but do not kill or remove them.

It is recommended an activated carbon filter such as ICS-ST or ICS-STP be used to improve taste and odor. It is also recommended a second arsenic filter be installed after the first to provide added protection against the first reaching capacity prior to being replaced.

For assistance with your treatment system please contact us and we will be happy to help. Maximum service life is 60,000 gallons or 1 year and may be less depending on your water quality and the volume of water treated.
