Kepulauan seribu (Seribu Archipelago) is one of region of north jakarta, the province of DKI Jakarta Raya which is populated by around 18.000 inhabitants. It consists of 111 small islands. Among them, there are about 11 (eleven) islands are stated as the residential:   P. Untung Jawa, P. Tidung Besar, P. Lancang Besar, P. Panggang, P. Pramuka, P. Kelapa I, P. Kelapa II, P. Harapan, P. Sebira. P. Payung dan P. Pari. P. Panggang and P. Kelapa I are the most populated.In relation to the clean water supply, specifically for drinking water/freshwater, mostly is got from the narrow well, rainfall and some water treatment installations that heve been owned by some islands. However, problem arises when the prolong dry season comes as the quality of water in the narrow well decreases significantly, the well water became brackish. In order to cope this problem, the avaibility of sufficient water treatment installations to process brackish water into freshwater is very important. The water treatment installation with reverse osmosis system is one of the most effective alternative in order to provide the freshwater for the people in the islands. The system has also been aplied sufficiently in several islands, such as P. Kelapa I, P. Tidung, P. Pramuka, P. Untung Jawa, P. Panggang dan P.

The clean water service of PDAM Loa Janan Sub-district has not yet reached all villages, including Batuah Village, which has not yet received clean water services from the government. To meet the need for clean water for the people of Batuah Village, they use drilled well water, dug water that does not meet health standards because it contains heavy metals that are toxic (poisonous). This activity aims to meet the needs of clean water for the community in Batuah Village. Activities start from identifying the potential and quality of raw water sources which include physical, chemical and biological parameters, designing and manufacturing clean water treatment units as well as testing the quality of water products produced, socialization and training to partner groups on the process of operating clean water treatment technology and monitoring the sustainability of the water treatment process after being managed independently by the partner group.

Quality Of Water

Quality of produced water is usually the criterion for selecting between different desalination technologies for turning seawater into drinking water. However, contemporary trend in drinking water treatment sees a convergence between different technologies for the same water quality. Hence, how do different desalination technologies differentiate amongst each other? Awareness of climate change impact as well as price of produced water, energy use per unit of treated water is an oft-used criterion for assessing the effectiveness and efficiency of different desalination technologies. Specifically, comparing multi-effect flash evaporation and reverse osmosis, the latter enjoys a significant energy use advantage given the lack of the need for converting water into the vapor phase as in multi-effect flash evaporation. Thus, energy used in producing drinking water is significantly higher in multi-effect flash evaporation compared to the high pressure process of reverse osmosis. From the operation perspective, reverse osmosis also benefits from its ability to scale linearly in increasing water production capacity through addition of extra membrane modules, which is not the case for multi-effect flash evaporation where a new distillation column is required for significant increase in production capacity. Collectively, with the same quality of water produced by different desalination technologies, comparison between different technologies increasingly relies on the energy use per unit of produced water. Using this criterion, reverse osmosis membrane desalination has a significant advantage relative to multi-effect flash evaporation in energy cost, which translates to a lower price of produced water.

Drinking Water Production

Modernization in water technology plays a major role in ensuring a clean, safe, and feasible supply of drinking water. Enhancing performance in terms of price and quality, flow ability of the plant, sustainable development; integrated membrane processes have been developed. The most crucial issues found in RO applications such as concentration polarization and membranes fouling are reduced by using this integration of membranes. Conventional reverse osmosis filtration has sand and coke filters as pre filters. In this work these pre filters have been replaced by ultra-filtration which ensures undoubtedly the best quality of water despite the quality of feed with low power consumption and chemicals. These integrated systems are the better thing for complete elimination of microorganism and water contaminants in their category of selection. The present work also contributes on water quality analysis for brackish water using both the above desalination membrane technology. This integrated system can be remotely monitored and self-adapted model-based control.

Community-based Water Drinking Supply and Sanitation is one of the programs implemented by the Government of Indonesia with the support of the World Bank. One of the government targets under the RPJPN 2015-2019 is that Indonesia can provide drinking water and sanitation services for the people of Indonesia. The ELECTRE method is chosen because it is able to select the best alternative from the existing alternatives. This research used seven criteria as reference in determining for recipient candidate for PAMSIMAS program. The number of incidents of diarrheal diseases in one year (number of incidents), the number of people who have not used safe drinking water (individual), the number of people who have not used the toilet, the financial ability of the region, the income of the villagers, the distance of the source of clean water from the settlement, the availability of clean water. In addition to the criteria is also used the quality of the criteria to determine the best alternative and from the calculation of the alternative obtained the greatest value contained in A4 with value E = 4 and alternative A5 with the value E =4 thereby alternatives 4 and 5 are viable alternatives to the prospective recipient villages of the PAMSIMAS program in Pringsewu district.

Rural Water

Provision of microbiologically safe drinking water for people living in the rural areas of developing countries remains a major challenge to date. One of the reasons is due to the inability to access potable water mainly because of poor existing water purification systems. Current measures have been put in place to address the challenges of rural water supply. Development of appropriate technologies such as decentralized water treatment supply in the form of point of use (POU) systems are been considered. In lieu of the above, an appropriate POU system known as the Remote Rural Water Treatment System (RRWTS) was developed at Durban University of Technology (DUT). The RRWTS is polyester based locally sourced Woven Fabric Microfiltration (WFMF) membrane system. The unit is made up of flat sheet modules that are assembled into a pack. It is a robust gravity driven system with the ability to remove suspended solids and colloids in the form of turbidity. The system has high flux of 35 ± 7 LMH and turbidity below 1 NTU, it has the ability to remove pathogens well above 95%. However, this does not comply with WHO and SANS drinking water standards of zero E. coli count/100 ml of treated water. In order to bring the water treated by RRWTS to a satisfactory level for drinking, it is then necessary to add a separate disinfection step like chlorination step to further remove the remaining microbial contaminants. Thus the main objective of the study was to evaluate the disinfection efficacy of two disinfectants namely waterguard and bromochlor tablet disinfectants and investigate their integration with the WFMF membrane. The study was categorised into three parts. The first part is the addition of disinfectants to unfiltered river water sources for the determination of residual chlorine and the most optimum dose that will yield effective disinfection and also evaluate the extent of E. coli removal by the disinfectants. The second stage was the filtration of four river water sources using the woven fibre membrane (WFM) to determine the efficiency of WFMF. Finally the effect of disinfection kinetics on disinfection was achieved by agitating the water after disinfection and allowing it to stand at different contact times. Performance of the RRWTS was determined by the amount of E. coli and turbidity removed during filtration using WFMF and by chemical disinfectants after filtration. The results on residual chlorine for different water sources showed that feed quality and disinfectant dose determines the quantity of residual chlorine on all the water sources. The effectiveness of chemical disinfectants in E. coli removal is affected by the quality of water to be disinfected. The study showed that turbidity plays a major role on disinfection by increasing chlorine demand on water sources with high turbidity levels. The WFMF demonstrated excellent filtration performance by producing permeates with turbidity less than 1 NTU for feed turbidities ranging from 10 to 200 NTU. The E. coli removal efficiency by WFMF was very high on all the water sources treated. There was 95-99.8% E. coli removal on raw feeds with influent E. coli ranging between 500 and 44500 CFU/100 ml. It was seen that major benefits are derived from integrating the WFMF (RRWTS) with chemical disinfection. The benefits includes; better disinfection that meets drinking water set guidelines of zero E. coli and improved quality of water. The need for disinfection kinetics in order to obtain superior disinfection was eliminated. The possibility of disinfection-by-product formation was reduced as smaller quantities of chemical disinfectants were required for complete disinfection on the filtered water.

Clean water is a serious problem in Indonesia, the availability of clean water has shrunk drastically due to deteriorating environment and pollution. Drinking water that meets safety standards is increasingly scarce. More than 100 million people need safe water sources. Filter media is able to remove chemicals in water such as turbid, odor, oily, yellowish, rusty and muddy making it unfit for consumption. In addition, the purpose of the clarification results must also be considered whether to drink household needs or other needs. This study uses Lauryl Tryptose Broth (LTB) media and petrifilm media. Petrifilm results show that it is very easy to count the bacteria Colifrom and Escerichia coli using petrifilm media. From the analysis of calculations using the Paired Samples T-Test on the sample before filtering and after filtering it was obtained the Tcount value of 2.28 with a P value 0.015 which showed very successful or significant results between the samples before and after the filter. In this analysis have normally distributed data with a significant value of P = 0.015 (<0.05). In this case the Paired Samples T-Test was tested for normality (Shapiro-Wilk) and the results were obtained in the form of a P value of <.001 which would indicate that the data was normally distributed, indicated by a P value <0.05. The filter on this filter is very useful for filtering on Escerichia coli bacteria because this filter removes the bacteria, but Colifrom bacteria can still escape the use of the filter, because it depends on environmental conditions. Colifrom and Escerichia coli bacteria occur is seen from the relationship between sources of pollution such as, for example, such as septic tanks, distance of wells with waste, trash, and livestock pollution. The quality of drinking water is very close to the presence of Colifrom and Escerichia coli bacteria which are likely to have pathogenic bacteria that are harmful to health in the quality of well water. Water samples to be observed using well water using 2 treatments as many as 12 repetitions. Thus the total sample obtained as many as 24 water samples will be observed. While the test making of Lauryl Triptose Broth medium was observed by incubating 48 hours at 35oC + gas. Before making the test tube medium must be sterilized first. Subsequent tests were observed with a petrifilm medium to determine the presence or absence of Colifrom and Escherichia coli bacteria by looking at the color of the battery being sought.

Las cuestiones relacionadas con el abastecimiento de agua potable y el saneamiento en las ciudades durante la transición de un sistema clásico de  abastecimiento, en el que las formas de acceso al agua en las ciudades eran múltiples y se carecía de un sistema de control estricto sobre la calidad de las  aguas consumidas, a uno nuevo, en el que se establece una red de cañerías para el abastecimiento y otra para la evacuación de las aguas servidas además  de proceder a cada vez más sofisticados sistemas de control bacteriológico y de potabilización, no han sido muy estudiadas en Chile a pesar de ser uno de  los grandes hitos de la urbanización en el cambio del siglo XIX al XX. Presentamos aquí los primeros avances en una investigación de mayor alcance en la  que estamos analizando las principales características del proceso de transformación en la gestión y el uso del agua en dos ciudades en pleno crecimiento  en la época que nos ocupa: Talca y Valparaíso. En esta ocasión nos circunscribimos sólo al caso de Talca. ABSTRACT The issues related to drinking water supply and sanitation in the cities during the transition from a classic supply system, in which the forms of access to  water in the cities were multiple and lacked a system of strict control over quality of water consumed, to a new one, in which the establish a network of  pipes to supply set and another one for the disposal of sewage, besides the use of more sophisticated bacteriological control systems and water treatment,  have not been enough estudied in Chile despite being one of the great landmarks of urbanization in the turn of the nineteenth and twentieth centuries. We  present here the firsts steps in a wider investigation in which we are analyzing the main features of the transformation process in the management and use  of water in two growing cities in the time before us: Talca and Valparaiso. This time we limit ourselves only to the case of Talca.
