Biosand Filter

In order to satisfy their need, people, who have limited access to safe water supply, use other available sources, which are not necessarily safe. Household water treatment systems (HHWTSs) has been proved useful to combat diarrheal diseases and achieve the seventh goal of the MDGs. Capability of one of these systems to increase safe water availability for people who lack to it was examined in this study. The study investigated possible HHWTSs for Bedouins in Jordan Valley as a community who had limited safe water supply and chose biosand filter, designed one and constructed and operated it on site. Its performance was examined for hydraulic (its flow rate) and bacterial and turbidity removal efficiencies. An idea regard Bedouins acceptance was formed. Biosand filter is a modified version of slow sand filter was firstly proposed by David Manz in 1991. Biosand filter as a HHWTS is characterized by simplicity, affordability and possibility to be constructed out of locally available material. Additionally, its operation and maintenance do not require high levels of knowledge. The results showed an average log reduction of 2.0 logs for total coliform and 1.82 logs for E. coli bacteria. Turbidity reduction averaged 98.8% achieving an effluent turbidity of 0.52 NTU. All turbidity values were <1.0 NTU. The flow rate was maintained stable with values around 0.51 l/min. The results were comparable to those obtained from similar studies. Being constant over study period, filtration rate has a distinctive property in this study. The filter cost was JD19 ($26.8). The Bedouins showed appreciation for the filter and its performance.

Design and fabrication of appropriate technology (biosand filter) that is directly can be applied for community has successfully been carried out for providing clean water. The technology is adopted from slow sand filter method. Biosand filter that has been fabricated which is technology that is able to filter river water become clean water through filtration process from sand, gravel and an active carbon. For getting drinkable water from river water, biosand filter has been combined with reverse osmosis system and ultraviolet disinfection. System of reverse osmosis and ultraviolet disinfection are used to reduce any bacteria, virus and total dissolved solids (TDS) from treated water which is resulted from biosand filter process. The results from Balai Besar Laboratorium Kesehatan Surabaya (BBLKS) has been declared that treated water from biosand filter is met the test standards chemical and physical according to the regulation. Meanwhile the processed water from process through biosand filter, reverse osmosis and ultraviolet disinfection is got predicate as drinkable water with met the test standards microbiological, chemical and physical.

The purpose of this research is to evaluate in relation to sustainable development, the BioSand Filter the
(BSF) project, implemented from 2011 to 2012 by the Global Engagement & Mobilization (GEM) team in Handong Global University. The aim of the BSF project is to improve the quality of water, one of the most important sectors for improvement included in the post-2015 Millennium Development Goals (MDGs). This research focuses on Goal 6 of the post-MDGs, “Achieve Universal Access to Water and Sanitation.” This research considers the possible impact of the BSF project on other goals in the perspectives of environment, socio-culture, and economics. The focus of this paper is to review the case study at Nakta Island located in the state of Bihar, India. Through a critical review, this research reveals the progress and challenge in achieving access to safe drinking water. This research aims to create policy suggestions for universities and students and the UNAI body in order to better prepare for similar projects in the future. The evaluation and analysis of this research confirm that a BSF model with sustainable development is the key to achieving Goal 6 along with the other targets of the post-MDGs.
