Improving the Efficiency of Natural Raw Water Pretreatment at Thermal Power Stations
Abstract In the treatment of make-up water for thermal power stations (TPS) and heat networks, raw water from surface water bodies is used. It contains organic and mineral pollutants in the form of particulates or colloids. Coagulation and flocculation are reagent methods for removing these pollutan...

| 520 | |a Abstract In the treatment of make-up water for thermal power stations (TPS) and heat networks, raw water from surface water bodies is used. It contains organic and mineral pollutants in the form of particulates or colloids. Coagulation and flocculation are reagent methods for removing these pollutants from water. Chemicals are used to assist in the formation of large structured flakes that are removed easily from water. The Kuibyshev water reservoir was selected as the object of investigation. Basic physical and chemical properties of the raw water are presented. The application of various coagulating agents, their mixtures in different proportions, and flocculating agents for clarifying the Volga water was examined. The required dose of a coagulant or flocculant was determined based on test coagulation of the treated water. Aluminum sulfate and iron (III) chloride were used a coagulant, and Praestol 2500 (nonionic) as a flocculant. A method of enhancement of coagulation and flocculation by injecting air into the treated water is examined. The results of experimental investigation of the effect of water treatment method on water quality indices, such as alkalinity, pH, iron content, suspended material content, and permanganate value, are presented. It is demonstrated that joint use of ironand aluminum containing coagulation agents brings the coagulation conditions closer to the optimum ones. Aeration does not affect the coagulation process. The methods for supplying air to a clarifier are proposed for practical implementation. | ||

It contains organic and mineral pollutants in the form of particulates or colloids. Coagulation and flocculation are reagent methods for removing these pollutants from water. Chemicals are used to assist in the formation of large structured flakes that are removed easily from water. The Kuibyshev water reservoir was selected as the object of investigation. Basic physical and chemical properties of the raw water are presented. The application of various coagulating agents, their mixtures in different proportions, and flocculating agents for clarifying the Volga water was examined. The required dose of a coagulant or flocculant was determined based on test coagulation of the treated water. Aluminum sulfate and iron (III) chloride were used a coagulant, and Praestol 2500 (nonionic) as a flocculant. A method of enhancement of coagulation and flocculation by injecting air into the treated water is examined. The results of experimental investigation of the effect of water treatment method on water quality indices, such as alkalinity, pH, iron content, suspended material content, and permanganate value, are presented.

It contains organic and mineral pollutants in the form of particulates or colloids. Coagulation and flocculation are reagent methods for removing these pollutants from water. Chemicals are used to assist in the formation of large structured flakes that are removed easily from water. The Kuibyshev water reservoir was selected as the object of investigation. Basic physical and chemical properties of the raw water are presented. The application of various coagulating agents, their mixtures in different proportions, and flocculating agents for clarifying the Volga water was examined. The required dose of a coagulant or flocculant was determined based on test coagulation of the treated water. Aluminum sulfate and iron (III) chloride were used a coagulant, and Praestol 2500 (nonionic) as a flocculant. A method of enhancement of coagulation and flocculation by injecting air into the treated water is examined. The results of experimental investigation of the effect of water treatment method on water quality indices, such as alkalinity, pH, iron content, suspended material content, and permanganate value, are presented. It is demonstrated that joint use of ironand aluminum containing coagulation agents brings the coagulation conditions closer to the optimum ones. Aeration does not affect the coagulation process. The methods for supplying air to a clarifier are proposed for practical implementation.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">water

Improving the Efficiency of Natural Raw Water Pretreatment at Thermal Power Stations |
| abstract |
Abstract In the treatment of make-up water for thermal power stations (TPS) and heat networks, raw water from surface water bodies is used. It contains organic and mineral pollutants in the form of particulates or colloids. Coagulation and flocculation are reagent methods for removing these pollutants from water. Chemicals are used to assist in the formation of large structured flakes that are removed easily from water. The Kuibyshev water reservoir was selected as the object of investigation. Basic physical and chemical properties of the raw water are presented. The application of various coagulating agents, their mixtures in different proportions, and flocculating agents for clarifying the Volga water was examined. The required dose of a coagulant or flocculant was determined based on test coagulation of the treated water. Aluminum sulfate and iron (III) chloride were used a coagulant, and Praestol 2500 (nonionic) as a flocculant. A method of enhancement of coagulation and flocculation by injecting air into the treated water is examined. The results of experimental investigation of the effect of water treatment method on water quality indices, such as alkalinity, pH, iron content, suspended material content, and permanganate value, are presented. It is demonstrated that joint use of ironand aluminum containing coagulation agents brings the coagulation conditions closer to the optimum ones. Aeration does not affect the coagulation process. The methods for supplying air to a clarifier are proposed for practical implementation. © Pleiades Publishing, Inc. 2018 |
