Filtration Media CMX-Lite™
100% Ceramic Filter Media
CMX-Lite™ is a uniquely engineered medium-to-coarse crushed angular grain ceramic media, offering superior performance and significantly lower operational costs than traditional filtration media. Various effective sizes and uniformity coefficients are available upon request.
Treating highly coagulated or turbid water
Removing inorganic contaminants, heavy metals, and organic particulate
Mono-media gravity filtration applications, or used in conjunction with a traditional sand filter
Propagating and/or protecting biofilms
CMX-Lite is a lightweight, expanded granular material that has ten times more surface area than anthracite in the optimal micron range for filtration. This extraordinary amount of surface area increases particle removal as compared to all other filter media and at a lower cost than anthracite. CMX‑Lite is 20% lighter than anthracite, resulting in reduced wastewater production which saves users valuable water.

CMX-Lite outperforms anthracite as a filtration media and backwashes at lower rates saving backwash water. It can also be used to cap anthracite to increase filter UFRV’s.

CMX-Lite has an exceptionally high surface area making it excellent for growing biofilm and it can be coated with all types of metal oxides including MnO2 for iron and manganese removal.

CMX-Lite is an inert and non-reactive media that is compatible with acid, caustic, and all types of oxidants. CMX-Lite can be used in harsh industrial filtration applications, chemical filtration, and in high temperature processes up to 1000ºF (538ºC).

CMX-Lite media is manufactured in the USA and certified to NSF/ANSI-61 standard for use in drinking water.
