Filtration Technology

The provision of clean water for all Indonesians is one of the objectives of the government that is still constrained by the limitations of the existing water supply infrastructure. Some areas, especially rural or remote areas, are still hard to reach by the clean water facilities of the Regional Water Company. Whereas the groundwater resources in this region are abundant but can't be explored optimally to meet the needs of clean water and proper consumption for the surrounding community. The availability of water is not balanced with its quality, especially as qualified water for consumption. Some other characteristics of rural areas such as poor sanitation and the presence of agricultural waste pollutants, result in groundwater quality being further away from the standard of consumption. Although there are some commercial water filtration technologies available, they are generally expensive, with limited capacity, and not intended for mass use. For that reason, a new breakthrough, by designing proper technology, which is not only affordable but also easy to use and have sufficient capacity to meet the needs of the community. This research used Quality Function Deployment followed by Functional Analysis Systems Technique to get the character of the user and design requirement of groundwater filtration technology which suitable with the community needs and water quality condition in rural areas. The result is a design of filtration technology consists of five main modules, namely filtration module, information module high voltage module, reactor module, and rack module. This design is expected to be the basis for developing clean water technologies for people in rural areas or others that are difficult to reach by the Regional Water Company infrastructure.

The Nagoya Waterworks and Sewerage Bureau has developed original supporting tools for the systematic and cost-effective management of problem solving. An environmental information map and prediction of pollutant reaching are used for rapid and appropriate proper countermeasures against water quality accidents in the source area. In disinfection byproduct control a method for estimating trihalomethane (THM) contents was effective for the complement of their observations. Surrogate indicators such as turbidity and conductivity that could be measured continuously also could complement water quality items measured monthly. A processing tool of voluminous data was practical for rapid judgment of water quality. Systematic monitoring was established for stricter turbidity control for measures against Cryptosporidium and keeping residual chlorine stable in the service area.

The shortage of fresh water creates acute challenges in the West Bank of Palestine. Springs provide a main water resource in the West Bank. Investigating springs’ water quality is essential step for promoting their public use. The aim of this research is to assess the microbiological and physiochemical quality parameters of drinking water from springs. The study methodology included sampling through field work and laboratory testing for water quality parameters using standard procedures. The study area covered all locations containing licensed springs by the Palestinian Water Authority in the West Bank of Palestine. The number of collected samples was 127 covering 300 springs. The chemical, physical, and biological parameters for each sample were measured. Then, the obtained characteristics were evaluated based on national and international quality standards (PSI and WHO). The investigated parameters included temperature, pH, EC, total hardness, concentrations of nitrate, sodium ions, total chlorine, residual chlorine, turbidity, and total and faecal coliforms. Most of investigated physical and chemical parameters were within the acceptable standard limits. However, the turbidity and chloride and nitrate concentrations exceeded standard limits. The findings indicate that only a minor fraction of the samples (2%) requires chlorination treatment, while most of the springs (97% of samples) are classified as possessing no risk.

Total coliform (TC) and faecal coliform (FC) bacteria were analyzed in drinking water of Khairpur city. Ninty samples were collected from main reservoir (source), distribution line and consumer taps. pH and residual chlorine of water samples were also determined. For bacteriological analysis inductively membrane filtration (MF) method was used for total coliform (TC) as well as faecal (FC) coliform bacteria. All samples were found contaminated with total coliform (TC) and faecal coliform (FC) and the counts were higher than the maximum microbial contaminant level (MMCL) established by World Health Organization (WHO). It was observed that pH was within the limits of WHO standard (6.5-8.5). The residual chlorine was not detected in any sample of drinking water. Bacteriologically the water quality of the drinking water is unsatisfactory.Keywords: Coliform, Escherichia coli, Water quality, Contamination, SanitationDOI: http://dx.doi.org/10.3329/bjm.v24i2.1266

Water quality safety is always a hot topic. Recently there has been a great increase in the use of polyethylene (PE) pipes in drinking water distribution systems in China. Some organics can leach from PE pipes into drinking water, which is undoubtedly harmful for consumers. In this study, potential organics leaching from two Chinese brands of PE pipe were investigated in order to determine the potential risk to both consumers and water quality. Their released amounts are characterized by UV254 instead of total organic carbon (TOC). Organics are identified by means of gas chromatography coupled with mass spectrometry (GC-MS). Influencing factors such as types of water, time, pH, residual chlorine are discussed. The cytotoxicity of leaching organics is first put forward in this study, and rat C6 glioma cell is used to assess the effect of leaching organics; the increasing dosage of soaking solution negatively affects morphology and relative viability of rat C6 glioma cell. The results show that residual chlorine, time and temperature have a positive effect on organics release, while pH plays an opposite role.

Using Shanshan County as the research focus, this study investigates drinking water safety in northwestern China and proposes measures for improving the efficiency of clean water projects targeting drinking water quality in the region. As new technologies such as the Internet and the Internet of things gain wider usage, urban and rural safe drinking water projects should focus on equipping projects, modularizing the equipment, improving project management using internetization, and developing intellectualization for increased Internet dependence. This study proposes modularization of the equipment for clean water projects for centralized and decentralized water supply programs. For management of such projects, this research proposes internetization in project management as well as intellectualization of construction, including establishment of management facilities, automation of water plant operations, intelligent control of clean water operations, and online intelligent water monitoring. This study integrates various information resources and investigates the implementation of intellectualized management of water treatment facilities through scientific advances and evaluates the potential of these approaches for increasing the quality of public service.
