Water Filters

Abstract Many households in Nigeria lack access to safe drinking water. Sixty-three percent (63%) of the nation's population live in rural areas where only 3% of households have access to safely managed drinking water. This suggests an urgent need for intervention to offer sustainable solutions to drinking water needs at household levels. An operational research was commissioned by the United Nations Children's Fund (UNICEF) Nigeria to generate evidence to inform and guide Water, Sanitation and Hygiene (WASH) programming on household water quality. This involved an assessment of local manufacturing of household water filters; factors influencing social acceptability and market opportunities for clay and biosand water filters in Nigeria. Implementation of the research recommendations by the filter factories resulted in improved bacterial removal efficiency (>97%) in filters. Factors such as filter design and efficiency were shown to influence acceptability of filters, which influenced the price at which users were willing to pay for the filters in the study areas. The market research indicated low popularity of the filters due to lack of promotion and marketing of the water filters. The research outcomes show great potential for sustainability and marketability of clay and biosand water filters for household water treatment in Nigeria.

Abstract Serving as the last barrier to secure drinking water safety, household water treatment and safe storage (HWTS) is perceived as an interim measure for removing pathogens from drinking water and reducing disease risk. In recent years, the application of HWTS has shown a growing trend, and its performance in controlling chemicals has also received much attention. Disinfection by-products (DBPs) are formed by the reaction of chemical disinfectants and precursors, and are present at sub-μg·L−1 or low-to-mid-μg·L−1 levels in drinking water. Although precursor control and disinfection operation modification could contribute to DBP mitigation to some degree, DBP removal after their formation emerges as an important strategy due to the ubiquitous existence of DBPs in distribution systems and tap water. In order to figure out how DBP concentrations vary during the residence time of drinking water in households, this review summarizes the effectiveness and mechanism of HWTS and combination technologies for DBP control in municipal tap water, and makes a comparison with regard to technologies implementing different removal mechanisms as well as DBPs possessing different natures. Based on these results, this article provides an insight into DBP risk assessment and human health protection.
