Research of Some Technological Aspects of the Nanofiltration
Method in Hybrid Desalination Systems of Caspian Sea Water
Abstract
The proposed article, based on a review of the work of a number of scientists in the field of ocean water treatment, shows the effectiveness of the primary nanofiltration method in preventing the formation of sulfate scales in desalination systems. The possibilities of the nanofiltration process in the treatment of Caspian Sea water were investigated in a professional computer program, and the high performance of NF200-400i membranes was determined. It has been shown that nanofiltration technology using this grade of membranes reliably protects reverse osmosis membranes and heating surfaces of thermal distillation units from sulfate deposits. It was found that using the nanofiltration method, it is possible to achieve an increase in the yield of desalinated water, a decrease in costs, and an increase in the temperature limit in the distillation process.
