Developing countries' experience is a huge gap in the coverage of collection-system and domestic wastewater treatment. Wherever the wastewater treatment facilities are available, they are running below the design standards. This leads to the discharge of pollutants into the natural water bodies and creating a negative impact on the environment and human health as well. Odor nuisance has become a major environmental issue worldwide with increasing public demand for better control of odor emissions from the municipal wastewater treatment facilities. Odor get affects the population directly and there is a trend that more and more peoples are becoming less tolerable with more odor emissions. Bad smell is often an indicator of the public potential health risk. Performance assessment of Haya water treatment plant in Manuma Village has been done. The main objective of this study is to assess the performance of the treatment plant with respect to produce high quality of treated water and reduce odor complaints. Influent and effluent samples were collected at critical treatment steps of the plant and analyzed for chemical, physical and microbial parameters. The study will be used to monitor the Manuma wastewater treatment plant and compare its performance to that one that uses the Sequence Batch Reactor (SBR) process. Study shows that process with wet scrubber technology will be the suitable treatment process to create an environment without any health-related issues, and selecting these alternative treatment facilities with the latest technology will lead to creating high-quality of treated water without any odor issues.

The important of ground water is increasing in the future as a source of fresh waters; in addition, many countries contain a number of water treatment plants to treat surface water. Using conventional treatment plant in the cities to treat ground water will decrease the cost of ground water treatment and may be help to depend on both surface and ground water supplies. This paper studied the ability of treating ground water by conventional water treatment. The quality of the ground water source is studied in the mention area during study period. The chemical quality of ground water is tested and there is within the standards of drinking water except iron.  The conventional treatment was enhancing quality of treated water by increment of dissolved oxygen concentrations toward optimum value. Water treatment plant was effective for removal of iron from ground water of about 50%, in addition there is an effect of conventional treatment on sulfate removal (sulfate may be increase above standards in some ground water sources). The statistical analysis of data shows there is a correlation between quality parameters of raw and treated water and between iron and sulfate of treated water in the correlation matrix. In addition, confidence test was applied on the correlation coefficients using fisher's transformation .The analysis shows, that there is a positive period (0.244, 0.941) of confidence of 95% of correlation factors of iron and sulfate.

Abstract: Water treatment plant (WTP) is essential for providing clean and safe water to the habitants. There is a necessity to evaluate the performance of (WTP) for proper treatment of raw water. The purpose of the present study is to evaluate the quality of treated water by investigating the performance of Ifraz-2 (WTP) units located in Erbil City, Iraq. For assessment of the (WTP) units, samples were taken for a duration of five months from different locations: raw water (the source), post-clarification processes, post-filtration processes, and from the storage tank. Removal efficiencies for the units, and for the whole (WTP) were calculated and presented. Obtained removal efficiencies for the sedimentation unit; filtration unit; and the entire Ifraz-2 (WTP) were 91.51 %, 64.71 %, and 97.29 %, respectively. After the process of disinfection and storage, the valued of the turbidity of the treated water were ranged from 1.2 to 9.7 (Nephelometric Turbidity Units) NTU. Besides, water quality index (WQI) for the (WTP) was studied and calculated for 14 physicochemical water quality parameters. WQI for Ifraz-2 (WTP) was 51.87 and it is regarded as a good level. Also, operational problems have been detected and reported during the research period, especially during sedimentation, filtration, and disinfection. Suitable solutions have been reported to the operational team.

Abstract Romania, has declared, by the Governmental Decision nr.352/2005, all its territory as a sensitive area. This implies that, for all urban agglomerations larger than 10.000 population equivalent waste water treatment plants (WWTP) with nutrient removal must be built or upgraded. This paper presents the results regarding the possible environmental impacts expected from the project for construction of waste water treatment plant in the City of Vaslui, with main focus on surface water. This research study includes assessment methodology, project description regarding the rehabilitation and extension of the Vaslui waste water treatment plant, data related to water resources, impact assessment on water and appropriate mitigation measures. The assessment of the impacts has been performed for the construction and operational phase of the wastewater treatment plant. The construction phase was subdivided into several phases, while in the operational phase the impacts are analyzed following the line for treatment of the wastewater and effluent production, the line for sludge production and drying process, sludge disposal in safety conditions considering the provisions of 86/278/EEC Directive and the line for biogas utilization.

This study aims to identify the most significant parameters in drinking water quality, spatial disparities of treated water (TW) and performance of water treatment plant (WTP) in Selangor. Physico- chemical (PCPs), Inorganic (IPs), Heavy metal and organic (HMOPs) and pesticide (PPs) were selected as parameters to discriminate the source of WTP pollutant. Chemometric technique such as principle component analysis (PCA), one-way analysis of variance (ANOVA) and discriminant analysis (DA) was applied to validate the performance of water treatment plant. PCA identified the most significant parameters which are highlighted six out of eight parameters for PCPs, six out of twelve parameters for IPs, nine out of sixteen parameters for HMOPs and all seventh parameters for PP. ANOVA for distinguish two categories region in WTP and showed both of PCPs and IPs had significant differences due to their concentration (p < 0.5) and HMOPs suggested fifth of significant differences within regions (p < 0.05). PP doesn’t give any significant differences (p > 0.05). DA was suggested PCPs, IPs and HMOPs in good performance (76.96%, 91.90% and 93.27%) except PP (50.43%). We can conclude that this chemometric technique can expose which area of WTP need to be properly maintains their performance to produce high quality of drinking water.

Currently the water supply system in the municipality of Corinto (Cauca) in Colombia provides drinking water to the entire urban and rural population of the municipality. In order to provide drinking water to the entire population, it became necessary to optimize and/or expand the existing water treatment plant. The article presents an assessment of the consideration of two optimization options: the need for reconstruction of existing water treatment facilities or the construction of additional water treatment units. A reasonable proposal was made to expand the station by building additional water treatment units, including advanced modern water treatment technologies, such as coagulation, flocculation, sedimentation, filtration, sorption, settling using thin-layer modules and disinfection, based on the survey (diagnostics), technical and economic analysis, analysis of the efficiency of the existing water treatment plant, taking into account the quality of drinking water preparation, confirmed by the analysis of samples, the results of physical, chemical and microbiological tests, indicating the optimal quality of drinking water for human consumption. The use of modern water treatment technologies will allow to achieve the required quality of purified sufficient water for drinking purpose.
