Comprehensive Saltwater Clearing Technology
Journal Title: Metallurgical and Mining Industry - Year 2018, Vol 10, Issue 2
Abstract
One of the major environmental problems at present is the salinization of surface and groundwater sources. Related to the increased discharges of mineralized sewage, this problem can be solved by complex processing. The current study investigates water demineralization with the purpose to create a comprehensive technology for the purification of high-salinity waters with chemical methods and to identify possible ways of utilizing their sediments as the binders or as the components for the binders. Grounded on the results of the study, the technology to apply the sediments in the building industry is proposed. The results of the study evidence that СаО and Na[Al(OH)4] can provide the effective water demineralization.
