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

SUMMARY

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.

Targeted energy audit of the industrial water mains and distribution networks

Summary

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.
