Technology of drinking water preparation using the reactor - clarifier

Siberian surface water and groundwater are characterized by low temperatures for a long year period. Many groundwater sources’ organic composition are formed of soil and peat humus, marsh feeding of rivers, decomposition of plankton, higher water, and soil grass in reservoirs and lakes. Organic colloids in natural waters and in humic substances give the color of water. It’s yellowish coloration of varying intensity. Thus, the Om River’s water color in the city of Kuibyshev in the Novosibirsk Region is 500 degrees with feculence of less than 3 mg/l. A number of underground water sources also have an increased content of organic contaminants caused by peat bogs at great depths and high water colority with low turbidity. For example, the water color is up to 1500 degrees in the Namtsy village of the SAHA-Yakutia Republic. In addition, underground water and, to a greater extent, surface water are often characterized by a high content of iron (up to 20 mg/l), manganese (up to 4 mg/l), and other impurities of natural and anthropogenic origin. Iron and manganese are in natural waters in the form of mineral or organic complex compounds of humic or some fatty acids. In the second case, these waters are with increased oxidizability and rather aggressive nature. In particular, the iron content is 3 mg/l, manganese is 1 mg/l, the permanganate oxidizability is 50 mg/l in the water of the Om River

Tertiary wastewater treatment using bioreactors-clarifiers

The use of technical oxygen instead of air in biological treatment plants can increase their oxidizing ability. Bioreactor-clarifier is a new technical device for tertiary wastewater treatment with the use of oxygen. The design, operation principle and research results of the bioreactor-clarifier for tertiary treatment of urban wastewater are given The use of bioreactors-clarifiers for tertiary treatment of urban wastewater using dissolved technical oxygen allows intensifying the process of biochemical oxidation of organic substances in a contact weighed load and increasing the efficiency of wastewater treatment by BOD and other components

Sludge conditioning of oil emulsion wastewater process by heat treatment using low temperatures in Siberia

The relevance of this study is due to the problem’s solution of preventing negative impact on the environment during the industrial waste disposal, as well as insufficient high-performance technologies for the treatment of sewage sludge in Siberian severe climatic conditions. Experimental studies of the properties, composition and structure of oil-emulsion wastewater sludge using x-ray phase and thermogravimetric analysis showed that the natural sludge, characterized by high humidity and a high value of specific filtration resistance is in an amorphous state The results of experimental studies on the conditioning process of oil emulsion wastewater sludge by heat treatment using low temperatures in the natural climatic conditions of Siberia are obtained. They can be used to develop effective technologies for processing and utilizing precipitation, which allows solving the problems of reducing the industrial impact on the environmen

Application of asymmetric current for electrocoagulation treatment of oil-containing waste water

The goal of the work was to study the electrocoagulation of oily wastewater using an asymmetric current and to determine the composition of the resulting sludge for disposal. The planning of the experiment according to Box-Hunter method was given and mathematical models - regression equations of the electrocoagulation process of oily wastewater using an asymmetric current were obtained. Optimization was performed by the dissociative-step method due to the regression equations. The structure and composition of sludge obtained under optimal electrocoagulation conditions using asymmetric current for the disposal of sludge in the arbolite mixtures production were studied. The results of experimental studies can be used to develop low-waste efficient, energy-saving technologies for wastewater treatment and waste management
