Treatment and Disinfection of the Don’s Water at Contact Filters Using the Coagulant SKIF180of the Latest Generation


The high efficient compact flowchart of treatment and disinfection of the Don’s water has been developed on the basis of experimental and theoretical studies carried out. In the process, mixers, coagulation chambers and sludge blanket clarifiers or settling tanks are eliminated from the scheme. The use of the method of contact coagulation with the high effective coagulant of SKIF™180 mark makes it possible to reduce reagent consumption by 65–70%, to exclude the necessity of primary disinfection of water with chlorine or reduce chlorine consumption to minimum, to ensure aluminum residual in water within the limits of MPC, to stabilize conditions of water treatment and reduce considerably the cost of water treatment.

Control of the technological processes at the water intakes
of Novokuznetsk


In recent years, a set of measures has been implemented at the operating water intakes of the city of Novokuznetsk using advanced equipment and technologies that have provided for improving the integrity and efficiency of the water supply system. It was noted that in order to achieve maximum efficiency of the water treatment facilities, continuous improving the technology of water purification is required. The most acceptable and economical solution to this problem is carrying out research works at the technological lab of the Dragun water supply facilities. The filtration properties of materials (expanded clay, burned rocks, albitophyre, quartzite, etc.) were studied that resulted in choosing the type of filter material and determining its optimal grain particle size for loading filters at the water treatment facilities. The most effective chemicals for water purification from the local water source, the Tom River, were identified. These are aluminum oxychloride coagulant and cationic flocculants. The introduction of a comprehensive process automation system provided for the control of the technical condition of the equipment and its process parameters, as well as for the data acquisition, processing and storage.

Targeted energy audit of the industrial water mains and distribution networks


In 2016 «Ostec-SMT» Company carried out a targeted energy audit of the drinking water supply networks at a wood processing plant in Siberia. The audit covered the water mains and distribution pipelines supplying water to the plant. The heart of the problem is the excess water losses (35% of the total water amount supplied by the public water supply system). The annual difference between the water amount purchased from the water services company and that supplied to the customers is 400 thousand m3. In order to locate the leaks it was decided to carry out consecutive measurements of drinking water flow from the interface of inventory responsibility, at the nodal points and at the service connections. The discovered water imbalance between the adjacent points, and leaks were determined with the use of a correlation leak detector. After the work completion the balance of the drinking water supply of the plant was compiled, the sections with losses were pointed out, and their quantitative estimate was given. The integrated study carried out by the experts of «Ostec-SMT» LLC provided for the exhaustive information on the state of the entire water supply system of the plant. The plant where the targeted energy audit of the water mains and distribution networks was carried out had implemented over the last years a number of large-scale investment projects, commissioned new and upgraded operating capacities.
