The Hanshin Water Supply Authority (HWSA) supplies drinking water to approximately 2.4 million consumers in the Hanshin area, including the city of Kobe. The HWSA has completed a project integrating two aging plants into a new water treatment plant (Amagasaki WTP) with a capacity of 373,000 m3 per day. The Amagasaki WTP has three significant special merits: water treatment, environmental, and information technology. The water treatment system is based on a multiple-barrier concept that estimates the value of water treatment technology not by individual processes, but by the overall performance of the system. The treatment train consists of coagulation/sedimentation, ozonation/activated carbon fluidized-bed adsorption, and coagulation/high-rate filtration, most of which fully utilize upward-flow. The key environmental technology characteristic of the new WTP is its achievement of zero-emissions. This design reduces CO2 discharge from the plant, as well as making it possible to completely recycle the sludge as an alternate material of agricultural and horticultural soils. Improvement of customer relations is a feature of the information technology. The authority provides information on the safety of the finished drinking water, watershed management, and the maintenance of source water quality. A visitors' area and emergency water supply facility for use in disasters have also been set up at the WTP. The Amagasaki WTP started commercial operation in April 2001. The completion of this renovated plant will significantly raise the quality of service to the customers.

Biological Nitrification

The implementation and evaluation of biological nitrification as a possible treatment option for the small-scale drinking water supply of a rural Upper Austrian community was investigated. The drinking water supply of this community (average system input volume: 20 m3/d) is based on the use of deep anaerobic groundwater with a high ammonium content of geogenic origin (up to 5 mg/l) which must be treated to prevent the formation of nitrites in the drinking water supply system. This paper describes the implementation and operation of biological nitrification despite several constraints including space availability, location and financial and manpower resources. A pilot drinking water treatment plant, including biological nitrification implemented in sand filters, was designed and constructed for a maximum treatment capacity of 1.2 m3/h. Online monitoring of selected physicochemical parameters has provided continuous treatment performance data. Treatment performance of the plant was evaluated under standard operation as well as in the case of selected malfunction events.

Treatment Train

A comprehensive fractionation technique was applied to a set of water samples obtained along a real drinking water treatment plant with ozonation and granular activated carbon (GAC) treatment to obtain detailed profiles of dissolved organic matter (DOM) and to evaluate the haloacetic acid (HAA) formation potentials of these DOM fractions. The results indicated that ozonation and GAC treatment showed limited ability to remove hydrophilic fractions (23%), while removal of hydrophobic fractions was 72%. The contribution of hydrophilic fractions to HAA formation increased from 30 to 61% along the treatment train because of better removal for hydrophobic fractions both in concentration and reactivity. Similar trends were also found for trihalomethanes.

Surface Water Treatment

During Autumn 1982, many consumers complained in Paris about a musty taste. Complaints were located only in a quarter of Paris which was supplied by a surface water treatment plant. The experiments and tests have shown that this taste appeared only in the network. Musty taste was detected neither on the river nor at the outlet of the plant. Some hypotheses have been made and experiments have been conducted later because this episode of complaints stopped suddenly. It appeared that some chlorophenols were produced in the plant. These compounds were biomethylated further by fungi in the network leading to chloroanisole which give a musty taste detectable a very low concentration.

Original Treatment

The renovating of a new water treatment plant in Paris which produces 15% of the capital's drinking water supply is described: an original treatment plant consisting of a preozonation, a flotation with a low level of coagulant coupled with contact coagulation. Coagulation on filter has been tested on a pilot plant. The results are excellent (95 to 99%) and have led to the building of a new water treatment plant with very flexible operating conditions depending on the quality of the water.

Supply Planning

Techno Park regional development in order to increase regional competitiveness based on innovation and knowledge (konwledge based economy) requires infrastructure that can meet basic human needs, such as drinking water supply for the community. Techno Park region Pelalawan, Riau province located in the peat so that most of the water source is brownish and contains peat. While surface water sources such as rivers Kampar located far from the region. Therefore, to overcome the problems of water supply for the people who will live in the region need to be prepared water supply planning. Early stages of development is focused on the areas of education and research zone so that planning for water supply will also be prioritized in both these zones. Has calculated the drinking water needs based on projected population and  water demand standard in these locations. Planning of water treatment plant will conduct  in  5 stages yearly so that development is more economic with design capacity of 5 l / sec in 2033. Alternative sources of raw water are from Kampar river or groundwater that is used if transmission pipeline from the Kapuas river has not ben constructed. Technology of drinking water treatment with ultrafiltration processes that are environmentally friendly will be applied to meet the water needs of society. Transmission pipelines is planned of 15 inches diameter laying in parallel with lane highway from Kampar River ( location intake BPAB ) to the water treatment plant in the education zone . Keywords : Techno park region, water supply planning, ultrafiltrasi, peat area.

AbstractTo elaborate efficient and economical water supply systems is one of the main objectives in the sanitation companies water system projects. In order to address the challenges faced in reaching this objective, this study aims to identify, first, the relation between the percentage of non-conformed samples in treated water and the inefficiency of the filtering units installed in the water treatment plant, and second, if, by drawing the consumption variation curve it is the most efficient way to predict the storage tanks volume—comparing necessary capacity, determined by the consumption curve, and installed capacity, predict by the outdated Brazilian normative. In order to reach answers for these two questions, this study measured the operating efficiency of the treatment plant as well as have set a quantitative comparison between the two dimensioning criteria for storage tanks volume present in the literature. As a result, the analysis provided the authors to detect a focus of contamination in the single-layered filtering units, limited by the filtering capacity of 2–6 m3/(m2 day), whilst operating at 333.13 m3/(m2 day). As well as to detect by the drawing of the consumption variation curve an oversize of 68% and 60% in the dimensioning of the studied storage tanks. With the results provided by this analysis approach, it was possible to efficiently detect and correct critical impairments in the treatment phase and to conclude that a long-term analysis should be drawn in order to affirm if the consumption variation curve is the best design methodology for the reservoirs.
