AbstractLow demand for safe water may partly result from a perceived distaste towards or the inconvenience of treatment methods. This paper analyzes preferences for water quality improvements in peri-urban Phnom Penh. The authors first analyze data from a discrete choice experiment in which respondents selected their preferred alternative from generic options varying in cost, taste acceptability, effectiveness against diarrhea and quantity of water treated. The choice patterns suggest that demand for water treatment is highly dependent on taste acceptability. The authors also use double-blinded taste tests to show that respondents are sensitive to one common taste in treated drinking water, that stemming from chlorine disinfection. While many compounds (natural and anthropogenic) may contribute to taste problems in drinking water, the lack of alignment between household preferences for taste and water safety may play a role in the low use of household water treatment methods in many settings.

The supply of clean drinking water is one of the most critical facets of primary health care, the main challenges of sustainable development in rural regions. However, Rajaf Payam experiences significant challenges in accessing clean and safe water. The study is designed to explore drinking water treatment methods in Rajaf Payam. Questionnaire was designed to conduct survey on sources of drinking water and drinking water treatment methods in the area, published articles included reports from the national government and some NGOs working in the rural drinking water sector were collected. So far 200 people participated in this study, from whom 60% were male, 40% female. However, 50 critical informant interviews and surveys were conducted, with 150 participants filling out questionnaires. The results show that 66% of the community use chlorine for drinking water treatment. Nonetheless, 19% are using boiling method, 10% using normal filtration (Water settling). At the same time, 5% know nothing about drinking water treatment. Therefore, this study recommending the Point-of-use (POU) of drinking water treatment technologies such as boiling, slow sand filtration, chemical disinfection, flocculation and coagulation, UV-C disinfection, and solar disinfection to the community of Raja Payam to enable them to access high quality drinking water and to avoid chronic drinking water related disease.

The Impact

SUMMARYWe compared the impact of a commercial chlorination product (brand name Air RahMat) in stored drinking water to traditional boiling practices in Indonesia. We conducted a baseline survey of all households with children <5 years in four communities, made 11 subsequent weekly home visits to assess acceptability and use of water treatment methods, measured Escherichia coli concentration in stored water, and determined diarrhoea prevalence among children <5 years. Of 281 households surveyed, boiling (83%) and Air RahMat (7%) were the principal water treatment methods. Multivariable log-binomial regression analyses showed lower risk of E. coli in stored water treated with Air RahMat than boiling (risk ratio (RR) 0·75, 95% confidence interval (CI) 0·56–1·00). The risk of diarrhoea in children <5 years was lower among households using Air RahMat (RR 0·43, 95% CI 0·19–0·97) than boiling, and higher in households with E. coli concentrations of 1–1000 MPN/100 ml (RR 1·54, 95% CI 1·04–2·28) or >1000 MPN/100 ml (RR 1·86, 95% CI 1·09–3·19) in stored water than in households without detectable E. coli. Although results suggested that Air RahMat water treatment was associated with lower E. coli contamination and diarrhoeal rates among children <5 years than water treatment by boiling, Air RahMat use remained low.

The Cost

Nanofiltration is a promising technology for water engineering. However, membrane fouling is the major bottleneck for NF application. In this paper, four typical methods, in the drinking water treatment trains, were comprehensively studied for their effectiveness as NF pretreatments, based on the organic removal improvement and membrane fouling mitigation. It was found that coagulation and UF had stably higher removal efficiencies of organic matters, whilst showed quite better fouling mitigation capabilities than the other methods. According to the analysis of total resistance changes in the NF membrane, coagulation could decrease the irreversible resistance to some extent, and improve the fouling recovery potential. Notwithstanding, the enhancement of nitrogen components by all pre-treatment methods were limited, indicating that further treatment would be necessary. This result herein was very useful to understand the NF process for drinking water treatment, as well to elevate the cost-effectiveness of NF application.
