...The biotechnology of cleaning the heat exchanger equipment by BiZ-1, BONAKA trademark, has proved its effectiveness, high degree of sediment removal, passivity with respect to brass pipes and other materials with which contact existed, as well as the possibility of draining into the general water disposal system. Separately, we note that BiZ-1 biocomposition has not had any harmful impact on either human health or the environment, which confirms its environmental safety. Having in mind the positive experience of using BiZ-1 biotechnology on peak boilers, it was planned to use it further for cleaning heat exchanging equipment at Krasnodar Heat Power Plant of LUKOIL-Kubanenergo LLC....

...Inspection showed that on the return water section (black pipeline), through which the solution was circulating, there are no deposits on the entire internal surface. The internal surface of the pipeline was clean and with dull metallic color. The inlet distribution manifold (the distributor of circulating water on the plates, the plates are stainless) was perfectly clean with silvery color. As a result of cleaning more than 15 kg of a grit was extracted from the heat exchanger. The experimental washing carried out showed a high efficiency of cleaning the plates of heat exchanger from the deposits of circulating water. We propose during stop repair of shop 2A to flush the plate heat exchanger, position E-603 and the inter-tube part of the inter-stage cooler position K102/3. Also washing of inter-stage refrigerators on compressors in shop #2 should be carried out....

...The deposits inside the tubes and on the heater covers were completely dissolved, which increased the heat transfer by 20-30%.. The technology using Bioorganic Composition (BIZ-1) TU 2634-001-36628895-10 Bonaca brand is recommended for cleaning of heating equipment and pipes in the boiler farm, because it is effective, environmentally friendly, safe and economically profitable....

...As a result of the cleaning, the pressure drop at the inlet and outlet of the heat exchanger equipment has significantly decreased the difference in temperatures at the inlet and outlet has returned to the passport values, both on the external circuit for heat consumers and on the internal circuit from the side of the boiler equipment....
A.A.Lykov - Director of AF of Teploenergoservis JSC
...Before cleaning, the inlet temperature (1 circuit/2 circuit) was 54/40 degrees, after cleaning, the temperature increased by 14 and 4 degrees, respectively, and the outlet temperature also increased. After cleaning, the pressure decreased noticeably (by 0.2 - 0.4 Bar), the water permeability increased. Thanks to high-quality work with the use of new technologies, it became warmer in our 5-storey office building!...

...The effectiveness of the work performed meets the requirements established by the contract. The purification level was 99%. The heat dissipation of equipment was increased by 25%. The results were given in a report. Taking into account the technological efficiency, the cleanliness of cleaning from the slurry and the scale of the reaction equipment on the basis of the BiZ-1 reagent (strain No. 18), by decision of the technical council of Krastsvetmet JSC this method was recommended for use...

...In July 2014, works were carried out to flush the heating system of the building of the GKKB No named after P.I. Pichugin (Perm). The heating system is single-pipe, the distributing and supply pipelines are made of a gas- and water conducting metal pipe, the radiators are cast-iron.
The heating system is brought into a normal (nominal) working state and there is no need for a major overhaul (replacement) of the heating system, which allowed to save about 948,264.52 rubles of budget funds and to create comfortable conditions for patients and the work of staff. The coefficient of heat transfer efficiency of the system has increased 2.61 times. ...
