Efficiency of common filters for water treatment in Tanzania

Abstract Background Approximately 69% of population in Tanzania lacks better sanitation, while 45.6% access to clean and safe water. To leverage this shortage, several technologies have been used for purifying water from various sources; however, there is still persistence waterborne diseases. Main body This article reviewed the efficiency common filters removing contaminants such as Escherichia coli , fluoride, TSS, turbidity, nitrate, virus, BOD, COD, fecal coliform color. Common available markets include slow sand filter, ceramic bone char, membrane purifier bio filter. The effectiveness each technology was evaluated terms its ability remove contaminants. Ceramic filter found be less expensive compared rest. Ineffectiveness can linked diseases Tanzania. Conclusion Ability viral removal greater concern. study suggests a best among all synthesized by locally materials clay, saw dust, rice husk ashes flour which make it efficient contaminants, especially viruses.
