The presence of natural or non-natural pollutants in water resulting from human activity such as the introduction of harmful agricultural and industrial pollutants into rivers that could be the main reason in forming trihalomethane compounds after chlorination step in drinking water production plants. Therefore, the objective of this paper was to assess the efficiency of traditional drinking water treatment plants in the removal of organic and inorganic pollutants (chemical and physical parameters). The Al-Hussein city water project as a traditional water treatment plant in Karbala governorate was taken with a capacity of 8000 m3/ has a model for this study. The physical and chemical properties of traditional plant was measured such as (Turbidity, Temperature, pH, Electric conductivity, Alkalinity, Total Hardness, Calcium, Magnesium, Chloride, Aluminum, Sulphate, Total dissolved salts) was taken from four units in the plant (quick mixing unit, sedimentation unit, filtration unit and disinfection unit). The average chemical and physical properties for both raw and drinking water were calculated for eight months during 2017-2018. The average removal percentage of turbidity was 60.7%. However, the values of the other tests ranged from 5 to -0.94%. In order to evaluate the presence of the organic substances in the plant. The samples for raw and drinking water were withdrawn in the winter and spring season from four units of the plant. The traditional plant show the removal efficiency of organic materials was 82% in the winter and 52% was in the spring season. The results showed that the physical and chemical properties were not significantly affected during the treatment process and their values were within the limits of the standard of drinking water. The traditional drinking water treatment plant considers unstable plant for the removal of organic compounds in the winter and spring with the possibility of forming chlorinated organic compounds. Therefore, there was the need to use additional treatment techniques to meet the challenges of new pollutants.

Abstract The article assesses the physical and chemical parameters of drinking water before and after the modernization of the technological system of water treatment station in Drzenin, Poland. The extension and modernization of the existing installation was necessary due to the poor technical condition of the devices, increasing demand for water in recent years and the periodic exceeding of the permissible values of water quality indicators. Analysis of physical and chemical properties of drinking water after the modernization of the system showed the effectiveness of the water purification processes used and the correct selection of the technological line. The obtained water quality parameters were in accordance with the Regulation of the Minister of Health on the quality of water intended for human consumption (Journal of Laws of 2017, item 2294).

Physical And Chemical

Some physical and chemical characteristics of Jurf Al- Sakar drinking water plant in Babylon governorate have been studied. Seven locations for this plant were selected. These were the drinking water treatment plant source on Euphrates River before entering the plant, precipitation, filtration and collection tanks, and also after leaving the plant at distances of one meter, 4 and 8 km. The samples were collected bimonthly from October, 2002 to August, 2003. Some results match with the national and international standard characters while the other characters (Turbidity, total hardness, calcium, nitrate, phosphate and the biological oxygen demand values) were not match. The present study showed that drinking water treatment plant is undrinkable, as well as, the chlorine is not used in the plant, during study period

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.

A Gram-positive, aerobic, non-motile, endospore-forming rod, designated DS22T, was isolated from a drinking-water treatment plant. Cells were catalase- and oxidase-positive. Growth occurred at 15–37 °C, at pH 7–10 and with <8 % (w/v) NaCl (optimum growth: 30 °C, pH 7–8 and 1–3 % NaCl). The major respiratory quinone was menaquinone 7, the G+C content of the genomic DNA was 36.5 mol% and the cell wall contained meso-diaminopimelic acid. On the basis of 16S rRNA gene sequence analysis, strain DS22T was a member of the genus Bacillus. Its closest phylogenetic neighbours were Bacillus horneckiae NRRL B-59162T (98.5 % 16S rRNA gene sequence similarity), Bacillus oceanisediminis H2T (97.9 %), Bacillus infantis SMC 4352-1T (97.4 %), Bacillus firmus IAM 12464T (96.8 %) and Bacillus muralis LMG 20238T (96.8 %). DNA–DNA hybridization, and biochemical and physiological characterization allowed the differentiation of strain DS22T from its closest phylogenetic neighbours. The data supports the proposal of a novel species, Bacillus purgationiresistans sp. nov.; the type strain is DS22T ( = DSM 23494T = NRRL B-59432T = LMG 25783T).

Treatment Step

The performance of a drinking-water treatment plant is determined by the control of the plant. To design the appropriate control system, a control-design methodology of five design steps is proposed, which takes the treatment process characteristics into account. For each design step, the necessary actions are defined. Using the methodology for the pellet-softening treatment step, a new control scheme for the pellet-softening treatment step has been designed and implemented in the full-scale plant. The implementation resulted in a chemical usage reduction of 15% and reduction in the maintenance effort for this treatment step. Corrective actions of operators are no longer necessary.
