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tanks volume—comparing necessary capacity, determined by the consumption curve, and installed capacity, predict by the outdated Brazilian normative.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.

The study analyzed possibilities of using ozone for water treatment in supply stations that provide water to small water supply systems. We analyzed a containerized water treatment plant (CWTP) in Mszana Dolna, located in Małopolska region, with a nominal production of 15 m3∙h-1. The plant uses a two step pressure filtration system with indirect water ozonation prior to active carbon filters. The treated water meets all the requirements set for drinking water. A cost analysis was also carried out to find out whether using this type of technology in small water supply stations in Poland is economically justified. The calculations were based on water production and its costs in 2017. The unit cost of water amounted to 0.59 and 0.77 EUR∙m3 for the variant taking into account a nominal water production and a hydraulic load of the station in 2017 that reached 58.7% f a nominal load.

Operational Diagnosis

Water supply systems represent one of the main components of municipal infrastructure. The operation of these systems is a complex task due to the several variables that interfere with the water distribution dynamics. The objective of the work was to obtain a diagnosis of the operation of part of the water supply system of Campina Grande and to find the main limitations and potentialities of the system infrastructure. The system supplies water to several municipalities, serving an urban and a rural population of more than 500,000 inhabitants. For the operational diagnosis, hydraulic modeling was done using the Epanet 2 simulator. The operation was modeled from the water treatment plant to the pressure zone 2 of the Campina Grande system. Cadastral surveys of the water network were carried out, field surveys and interviews with the operators. Based on the scenarios analyzed it was possible to conclude that zone 2 of the supply system has little margin for increase demand , around 10%, that the system can not work outside the peak hours and the energy cost is mainly generated by the station of water treatment. In order to improve the vulnerability reduction operation, investments are required in the physical structure of the system and in monitoring and automation.

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.

Sumber air baku yang direncanakan sebagai sumber air Water Treatment Plant ( WTP ) di Kota Lhokseumawe salah satunya adalah di Desa Ujung Pacu, Kecamatan Muara Satu, Pemerintah Kota Lhokseumawe, yang direncanakan berasal dari air permukaan ( surface water supply) diambil dari Sungai Ujung Pacu. Studi ini bertujuan secara umum untuk melakukan analisis hidrologi dan kualitas air baku sebagai pengembangan potensi Desa Ujong Pacu sebagai kawasan sumber air baku penyediaan air minum bagi Kota Lhokseumawe. Data yang dikumpulkan meliputi data hidrologi ( debit sungai, pengukuran pasang surut, evaporasi ) dan data laboratorium air baku. Dari hasil pengolahan dan analisa data diketahui bahwa debit rerata Sungai Ujong Pacu selama survey pengambilan data adalah 12,279 m3/detik, dengan debit terkecil yang terjadi adalah sebesar 6,627 m3/detik atau 6627 liter/detik. Debit minimum ini telah cukup untuk WTP yang direncanakan dengan kapasitas 50 liter/detik atau 1,524 cfs. Naik dan turun air permukaan sungai karena pasang naik dan surut air laut terjadi mak simal nya rata-rata lebih kurang selama 9 jam tiap harinya. Evaporasi terbesar terjadi pada bulan Agustus, yaitu sebesar 13,868 mm/hari. Nilai evaporasi ini adalah sebesar 10,413% dari total evaporasi harian tiap bulannya selama setahun. Nilai ini masih di bawah nilai persentase evaporasi maksimum yang biasa terjadi pada bulan evaporasi maksimum yaitu sebesar 20%. Sungai Ujong Pacu adalah sungai dengan kandungan bahan organik yang tinggi, air baku tidak ada indikasi tercemar logam berat, meskipun demikian air tidak memenuhi syarat sebagai air minum, tapi memenuhi syarat sebagai sumber bahan baku air minum dengan treatment tertentu.Kata-kata kunci: Water Treatment Plant ( WTP ) , analisis hidrologi, kualitas air baku
