Household ceramic water filter evaluation using three simple low-cost methods : membrane filtration, 3M Petrifilm and hydrogen sulfide bacteria in northern region, Ghana

Drinking water continues to be a major source of waterborne diseases and death in the world because many points of water collection remain unsafe. This thesis reports high level of fecal contamination found in rivers and ponds that are major sources of drinking water supply for the local communities in and around Tamale, in the Northern region of Ghana.

One such solution is household water treatment and safe storage HWTS), which is being promoted globally by the World Health Organization, international reference to promote household water treatment and safe storage. HWTS products are sold locally by Pure Home Water (PHW in Tamale. This work explores the microbial removal and flow rate performance of two of the PHW best sellers: the CT.
