Using a Dual-Flow-Counterflow Na-Cationite Filter in Processing Geothermal Waters

Today, more than ever, the issue of environmental safety in general and, in particular, the protection of the environment from aggressive pollution arising from the operation and operation of engineering and communication systems. Therefore, there was a need to create environmentally friendly, as well as cost-effective technologies that meet modern requirements. As known, the question is also relevant at the present time use of alternative energy sources instead of traditional ones or their sharing. For application of geothermal waters in systems heat supply, heating, industrial technological processes and agricultural industry, its salt content must be brought to the required standards. To prevent the formation of solid, practically insoluble precipitation on the heat exchange surfaces of thermal equipment is mandatory the condition is the removal of hardness, alkalinity and sulfates. Since, these ions precipitate in the form of scale. It is for this reason that in heating systems to prevent the formation of scale is supplied softened network water. This article discusses a new technology softening of geothermal waters, which will be used as coolant. The article is devoted to a detailed analysis of the processing of geothermal water with a Na-cationite filter. Softening methods are also compared geothermal waters by cocurrent and countercurrent methods. Showing advantages of using a new developed technology for processing thermal water using a two-flow-counter-current cationic filter. In the article schematic diagrams of a water treatment plant with a drainless water softening based on direct-flow and counter-flow Na-cationite filter. The developed method for the treatment of geothermal waters on two-flow countercurrent filters is a new promising direction both in the preparation of water for systems heat supply and the use of alternative energy sources.
