Surface Water Supply

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

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.

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.

Quantitative Monitoring

The research presented in this manuscript concerns the evaluation of the effectiveness of microstrainers, which are designed to reduce the amount of plankton in treated surface water. The efficiency of microstrainer filtration analysis is very important for the proper course of the water-treatment process not only in the Water-Treatment Plant (WTP) in Zielona Góra (central western Poland) but also in other WTPs around the world. The qualitative and quantitative monitoring of the abundance of plankton including cyanobacteria during the particle-filtration process allows not only for the assessment of the potential cyanotoxic risk in surface water providing a source of drinking water, but also allows the evaluation of the action and the prevention of adverse impacts of microstrainers. Over four years of research, it was observed that the largest amount of cyanobacteria before microstrainer filtration took place in May. The dominant species was Limnothrix redeckei. The microstrainer removal of plankton and cyanobacteria was statistically significant. The quantity of removed plankton increased with its increasing content in raw water. The particle-filtration process, by reducing the amount of cyanobacteria, contributes to a decrease in intracellular microcystins.

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.

Water Treatment Technology

A technological investigation was carried out over a period of 2 years to evaluate surface water treatment technology. The study was performed in Poland, in three stages. From November 2011 to July 2012, for the first stage, flow tests with a capacity of 0.1–1.5 m3/h were performed simultaneously in three types of technical installations differing by coagulation modules. The outcome of the first stage was the choice of the technology for further investigation. The second stage was performed between September 2012 and March 2013 on a full-scale water treatment plant. Three large technical installations, operated in parallel, were analysed: coagulation with sludge flotation, micro-sand ballasted coagulation with sedimentation, coagulation with sedimentation and sludge recirculation. The capacity of the installations ranged from 10 to 40 m3/h. The third stage was also performed in a full-scale water treatment plant and was aimed at optimising the selected technology. This article presents the results of the second stage of the full-scale investigation. The critical treatment process, for the analysed water, was the coagulation in an acidic environment (6.5 < pH < 7.0) carried out in a system with rapid mixing, a flocculation chamber, preliminary separation of coagulation products, and removal of residual suspended solids through filtration.
