In the scope of the work, an analysis of the water supply of residents of the Donetsk region and other regions of Ukraine with natural and anthropogenic sources of water suitable for further processing was carried out, the chemical composition of waters of various origins was determined, and the possibility of their additional processing to provide consumer properties was determined. Possible methods of pre-treatment of water are proposed, which ensure long-term and uninterrupted operation of baromembrane installations.

Methods of water pre-treatment before baromembrane installations in order to remove the predominant amount of salts are proposed. The technological scheme of obtaining high-quality permiate in the amount of 90-95% of the initial volume of water during its preliminary stabilization treatment has been developed. The influence of various factors on the quality and yield of permiate has been established.

New methods have been developed for sample preparation and analysis of heavy metal ions in water based on polarography, which provide an accuracy of 2-6 orders of magnitude higher than those known today. Methods for determining trace concentrations of heavy metal ions in water have been developed. New processes of separation and removal of ions of heavy metals, chromates and other anions from acidic and alkaline solutions have been studied and developed to produce metals and chemical reagents suitable for reuse.

As the volume of work created new ways of obtaining highly basic aluminum coagulants, which are based on the interaction of aluminum hydroxide and magnesium and calcium sodium aluminate coagulants with hydrochloric acid and can be effectively used in the process of softening water and lighting. An polikationit new flocculant by polycondensation of amines and epichlorohydrinе and polyacrylamide during amination by condensation with amines and formaldehyde. Developed new scientific approaches to the removal of heavy metals from galvanic.

The processes of illumination of low mineralized and salt waters are studied with the use of additional reagents. Possibility of the use and efficiency are set in the processes of illumination of different types of coagulants and flokulants, selected most suitable from them for illumination of low mineralized, the optimal doses of reagents, condition of their use are certain, limiting factors that determine efficiency of discolouration with the help of chemical reagents are set. The processes of the reagent softening of waters of this type are studied.

This work is aimed at the creation of scientific bases of desalination and purification of highly mineralized water without the formation of liquid waste to developing an integrated water conditioning technology, which provides softening and desalination of water, its decontamination and stabilization with respect to scaling to meet the needs of utility and industrial companies.
