Bacteria One-celled organisms that are present in everything from water to food. Bacteria can be found in virtually any water system. Municipal water systems check for harmful bacteria levels on a regular basis. Hetertrophic bacteria are considered safe for the general population, but they can cause taste and odor problems. Carbon Block Activated carbon mixed with chemical binders to form a hard block of carbon, which is then cut and shaped to fit the filter housing.
Sediment removal is dependent on the micron rating.
Higher carbon content removes odors and off-tastes. There are submicron carbon block filters that remove smaller-sized particles, providing cyst reduction. These filters must be handled carefully as they can crack, causing an undetectable by-pass. Often the aftermath of the two step ammonia plus chlorine disinfection method used at large, central municipal-type treatment plants. They can produce a disagreeable taste and odor.
