Kruger Ceramic Membrane (KCM)

Standard KCM Skid

Kruger Ceramic Membrane (KCM)

The Kruger Ceramic Membrane (KCM) Purification System utilizes a porous ceramic microfiltration membrane surface overlayed on a sturdy monolithic ceramic structure. The nominal pore size of the ceramic membrane surface is 0.1 micron which provides an effective barrier removing bacteria and protozoa such as Cryptosporidium and Giardia.

The ceramic microfiltration system provides stable treatment of raw water with widely varying inlet characteristics, while producing excellent filtered water quality. Low backwash frequency and dead end filtration results in high filtered water recovery rates and low energy consumption

The article "New Treatment Plant to Feature Ceramic Membranes" describes the process that will be installed to treat water from the Rueter-Hess Reservoir (RHR).
