Приводятся основные результаты технологических изысканий, положенных в основу проекта реконструкции станции очистки подземных вод г. Ноябрьска (Ямало-Ненецкий автономный округ). Станция построена по проекту ЗАО ДАР/ВОДГЕО (Москва) и принята в постоянную эксплуатацию в сентябре 2006 г. На станции используется новая технология, предусматривающая последовательную обработку воды двумя окислителями пероксидом водорода и перманганатом калия с целью очистки от соединений железа и марганца. Недостатки проекта и неполная реализация проектных решений усложняют штатную эксплуатацию станции и затрудняют получение питьевой воды нормативного качества. Установлено, что в подземной воде присутствует сероводород в концентрациях до 0,1 мг/дм3, что требует дополнительного расхода реагентов. Ручное дозирование реагентов приводит к значительным отклонениям от необходимых доз: от 14,5 до 19,1 для пероксида водорода и от 8,5 до 9,1 для перманганата калия. Указано, что применяемые в качестве реагента технические продукты перманганата калия производства КНР создают угрозу увеличения токсичности питьевой воды. Найденное значение величины индекса Ланжелье (индекса насыщения карбонатом кальция) подземной воды (2,35 ед.) позволило сделать вывод о необходимости стабилизационной обработки путем подщелачивания. Выполненные пробные обработки воды пероксидом водорода и перманганатом калия в сочетании с подщелачиванием показали, что такой процесс обеспечивает достижение остаточных концентраций марганца 0,1 мг/дм3 и железа общего 0,10,15 мг/дм3 при отсутствии остаточного сероводорода. Однако для получения воды постоянного нормативного качества необходима высокая точность дозирования реагентов, что может быть достигнуто только путем полной автоматизации процесса. Выполненный на основе технологических изысканий проект реконструкции станции очистки подземных вод г. Ноябрьска позволяет решить существующие проблемы и обеспечить нормативное качество очищенной воды.The main results of technological surveys that form the basis for the project of reconstruction of the ground water treatment plant in Noyabrsk (Yamalo-Nenets Autonomous Okrug) are presented. The plant was built according to the project of DAR/VODGEO CJSC (Moscow) and commissioned in September 2006. The plant uses a new technology that provides for the sequential treatment of water with two oxidizing agents hydrogen peroxide and potassium permanganate to remove iron and manganese compounds. The project shortcomings and incomplete implementation of design solutions complicate the regular operation of the plant and make it difficult to ensure the standard quality of drinking water. It was stated that ground water contained hydrogen sulfide in concentrations up to 0.1 mg/dm3, which required extra consumption of chemicals. Manual dosing of chemicals causes significant deviations from the required doses: from 14.5 to 19.1 for hydrogen peroxide and from 8.5 to 9.1 for potassium permanganate. It is pointed out that crude products of potassium permanganate produced by the P. R. China used as a chemical agent in drinking water supply, pose a threat of increased toxicity of drinking water. The determined value of the Langelier index (index of saturation with calcium carbonate) of ground water (2.35 units) allowed to conclude that stabilization treatment by alkalization is required. The performed test water treatment with hydrogen peroxide and potassium permanganate in combination with alkalization showed that this process provided for achieving the residual concentrations of manganese 0.1 mg/dm3 and total iron 0.10.15 mg/dm3 in the absence of residual hydrogen sulfide. However, to produce water of constant standard quality, high accuracy of chemical dosing is required that can only be provided by completely automated dosing. The project of upgrading the ground water treatment plant in Noyabrsk designed on the basis of technological research, allows to resolve the existing problems and ensure the standard quality of drinking water.

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 There are presented results of technological experiments carried out in Water Treatment Plant Kúty. The goal of this study was to compare modified zeolite known as clinoptilolite (rich deposits of clinoptilolite were found in the region of East Slovakia in the 1980s) with the imported modified zeolite from deposit situated in Hungary. Klinopur-Mn and Klinomangan were used for removal of iron and manganese from ground water to meet the requirements of the Regulation of the Government of the Slovak Republic No. 496/2010 on Drinking Water. The materials observed exhibit different efficiencies of manganese removal from water, since the quality of the treated water play a major role (oxygen content and pH value). In the case of the removal of the iron from the water, the quality of the raw water is not a limiting factor; both materials removed Fe from the water to below the limit value (0.20 mg.l-1).

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.

Abstract Unlike urban and semi-urban settlements where the potable water is supplied through a water treatment plant and a distribution network, in rural low-income settings, the provision of the water treatment plant for all villages is not feasible for a developing country like India. The most affordable and reliable way to provide clean drinking water is treatment at the consumer end. This research is aimed to assess occurrence of water-borne diseases based on personal hygiene and quality of drinking water source. Of the households, 4,237 in 15 selected villages were surveyed for personal hygiene using a questionnaire. Water samples were collected from all major water sources in the villages and analyzed for chemical and bacteriological properties. For water and personal hygiene, quality indices were calculated, and a mathematical model was developed using multiple linear regression analysis. The regression concluded that personal hygiene has a more significant effect on the occurrence of water-borne diseases than the quality of water source in the study area. Personal hygiene is one of the health factors neglected by the people specifically in rural India. Therefore, India needs to run campaigns like Swachh Bharat Abhiyaan (Clean India Mission), which was mainly aimed to reduce open defecation, to promote personal hygiene and to reduce the prevalence of water-borne diseases.

The Impact

Increasing of drinking water quality at real water treatment plant by recarbonization process According to the World Health Organization, chemical and microbial contaminants in drinking water will continue in the interest of suppliers of drinking water. The review establishment of new knowledge for drinking water including the potential benefits of the mineral content is necessary. The paper is focused on an assessment of the quality of water from surface source for drinking water preparation and quality of drinking water produced at the real plant. The lab-scale verification of water recarbonization with lime and carbon dioxide was chosen based on the results of full scale plant data analysis. Recarbonization tests were carried out with the raw water and the impact of recarbonization on coagulation process at different coagulant doses was studied. The results show that water recarbonization had adverse influence on the water treatment processes.

Llobregat River

The Llobregat is a 156 km long river, which supplies 35% of the Barcelona's drinking water needs from the Sant Joan Despí Water Treatment Plant. Since the establishment of the Salt Mine Works in the Llobregat basin in 1923, a progressive salinization of the water sources has been recorded. The operation of the Brine Collector, as a public work carried out by Aigües de Barcelona (AGBAR), started in 1989; it enabled a very significant improvement in the quality of the surface water used for drinking-water production.
