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.

Drinking Water Production

Abstract Several pharmaceuticals were followed through a drinking water production process on the river Meuse. Tramadol and levetiracetam were the most common compounds while cytostatics were not detected. All compounds found at that intake point had an annual consumption greater than 90 mg/inhabitant. The tracer substance 1,2,3-benzotriazole allowed estimation of the maximal concentration of pharmaceuticals and the evolution profile for tramadol and sotalol. After pre-ozonation of raw water, most pharmaceuticals were completely removed, except levetiracetam and irbesartan, confirming the efficiency of this advanced oxidation process. Irbesartan and levetiracetam were completely removed by granular activated carbon filtration. Levetiracetam was the most reluctant compound. A conventional multi-barrier treatment combining ozone and activated carbon, already used for several decades before implementation in wastewater treatment, can completely remove most pharmaceuticals. Therefore, drinking water without any significant health-related amount of these pharmaceuticals can be produced from surface water.

Drinking Water Production

AbstractElevated concentrations of ammonium and methane in groundwater can cause severe problems during drinking water production. To avoid their accumulation, raw water in the Netherlands, and many other countries, is purified by sand filtration. These drinking water filtration systems select for microbial communities that mediate the biodegradation of organic and inorganic compounds. In this study, the active layers and wall biofilm of a Dutch drinking water treatment plant (DWTP) were sampled at different locations along the filtration units of the plant over three years. We used high-throughput sequencing in combination with differential coverage and sequence composition-based binning to recover 56 near-complete metagenome-assembled genomes (MAGs) with an estimated completion of ≥70% and with ≤10% redundancy. These MAGs were used to characterize the microbial communities involved in the conversion of ammonia and methane. The methanotrophic microbial communities colonizing the wall biofilm (WB) and the granular material of the primary rapid sand filter (P-RSF) were dominated by members of the Methylococcaceae and Methylophilaceae. The abundance of these bacteria drastically decreased in the secondary rapid sand filter (S-RSF) samples. In all samples, complete ammonia-oxidizing (comammox) Nitrospira were the most abundant nitrifying guild. Clade A comammox Nitrospira dominated the P-RSF, while clade B was most abundant in WB and S-RSF, where ammonium concentrations were much lower. In conclusion, the knowledge obtained in this study contributes to understanding the role of microorganisms in the removal of carbon and nitrogen compounds during drinking water production. We furthermore found that drinking water treatment plants represent valuable model systems to study microbial community function and interaction.HighlightsMicrobial distribution was mainly influenced by sampling location within the DWTPClade A comammox Nitrospira were the dominant nitrifiers in the primary sand filterClade B was most abundant in samples from wall biofilm and the secondary filterA novel Methylophilaceae-affiliated methanotroph dominated the primary sand filter

Minimum Requirements

This paper presents the development and implementation of a centralized industrial network for an automatic purified water production system used in the pharmaceutical industry. This implementation is part of a project to adapt an industrial plant to cope with advances in industrial technology to achieve the level of Industry 4.0. The adequacy of the instruments and the interconnection of the controllers made it possible to monitor the process steps by transforming a manual plant, with discontinuous production into an automated plant, improving the efficiency and quality of the produced water. The development of a supervisory system provides the operator with a panoramic view of the process, informing in real-time the behavior of the variables in the process steps, as well as storing data, event history and alarms. This system also prevented the collection of erroneous or manipulated data, making the process more transparent and reliable. Accordingly, we have been able to tailor this water treatment plant to operate within the minimum requirements required by the regulator.

Источники питьевого водоснабжения (реки Великая, Волга, Вычегда, Которосль, Лименда, Солда, Северная Двина, Томь и Тура) характеризуются повышенным содержанием органических соединений природного и антропогенного происхождения. Традиционная технология двухступенчатого осветления воды коагулированием в данном случае по своей эффективности не соответствует качеству воды источника, в результате по некоторым показателям питьевая вода периодически не отвечает современным требованиям стандарта. Особенно сложно обеспечивать в питьевой воде предельно допустимые концентрации органических веществ, а также соединений железа, марганца и остаточного алюминия. Для очистки такой воды были изучены дополнительные методы окисления и сорбции. Результаты исследований показали, что предварительное озонирование речной воды и (или) постозонирование воды после фильтров станции водоподготовки повышают эффективность очистки по цветности, мутности, удалению соединений железа и марганца, уменьшают концентрацию остаточного алюминия, улучшают органолептические показатели. Сорбционная очистка с озонированием существенно улучшает качество очищенной воды и позволяет обеспечить допустимый уровень содержания органических загрязнителей в питьевой воде. Sources of drinking water supply (the Velikaia, Volga, Vychegda, Kotorosl’, Limenda, Solda, Severnaia Dvina, Tom’ and Tura rivers) are characterized by increased concentrations of organic compounds of natural and anthropogenic origin. The traditional technology of two-stage water clarification by coagulation in terms of the efficiency, in this case, is not applicable to the quality of the source water; as a result, by some indicators, drinking water periodically does not meet the current standard requirements. It is especially difficult to ensure the permissible maximum concentrations of organic substances in drinking water, as well as of compounds of iron, manganese and residual aluminum. To provide for the purification of such water, additional oxidation and sorption methods have been studied. The research results showed that preliminary ozonation of river water and (or) post-ozonation of water after filtration at a water treatment plant provide for increasing the efficiency of purification in terms of color, turbidity, removal of iron and manganese compounds; for reducing the concentration of residual aluminum, and improving the organoleptic characteristics. Sorption with ozonation significantly improves the quality of treated water and allows to ensure the permissible level of organic pollutants in drinking water.
