Water treatment for energy in Ukraine
The operation of energy enterprises is associated with the use of large amounts of water. Most of the water (more than 90%) is used in the cooling systems of various devices: turbine condensers, air and oil coolers, etc.
Wastewater in such facilities can be any stream of water that is removed from the cycle.
Waste water characteristics:
Waste or waste water, in addition to water from cooling systems, includes: water from hydraulic ash recovery systems (GZU), waste solutions from chemical washing of equipment or its conservation, regeneration and washing water from water treatment plants, wastewater contaminated with oil products, solutions and suspensions that are formed during surface washing heating.
Applied cleaning technologies:
- neutralization;
- mechanical cleaning;
- upholding;
- coagulation, flocculation;
- flotation;
- biochemical purification;
- sorption;
- dehydration;
- disinfection.
The main task of water treatment in the energy sector is partial or deep water desalination. This process is necessary to remove impurities that form deposits on heat exchange surfaces, on turbine blades; causing equipment corrosion. Therefore, the reliable operation of power plant equipment largely depends on the right technology.
Most of the large energy facilities in Ukraine, Russia, etc. countries of the former USSR were built more than 20 years ago. Almost all of them use water treatment for energy based on ion exchange technology, less often – evaporators. To date, such VPU are outdated both physically and morally. Often, the existing schemes of TLU are non-environmentally friendly, energy-consuming, with a low level of automation. A high degree of wear also leadsThis leads to a decrease in the quality of the treated water, frequent repairs, downtime, and – consequently – to additional costs. When reconstructing/modernizing/constructing new WLUs at existing or newly constructed power facilities, membrane technologies or a combined scheme using traditional technologies are predominantly chosen.
We offer modern solutions for the reconstruction of existing water treatment plants for energy throughout Ukraine, for example, in such cities as Kyiv, Dnipro, Lviv, Odessa, Zaporozhye, etc. as well as for newly built facilities. The existing experience of working with energy enterprises allows us to successfully implement reconstruction projects in the conditions of a working enterprise with virtually no interruption of the water treatment process. In our solutions, we use membrane technologies and modern countercurrent ion exchange schemes using the “clamped layers” technology.
