Abstract
Improving industrial waste treatment processes is associated with solving environmental problems that involve saving consumed environmental resources and reducing the volume of waste disposed of in it. Both are achieved through the introduction of low-waste technologies with the ability to extract valuable components and use purified water in the recycling cycle, among which electro-membrane technologies occupy a worthy place. The paper considers the possibility of using electromembrane separation in the treatment of technological solutions of treatment facilities of RKS-Tambov. In order to study the influence of the parameters of the separation process on the main kinetic characteristics, experimental studies of the specific productivity and retention coefficient of MGA-95 and OPMN-P membranes were carried out during the separation of technological solutions from PO43- phosphate ions. Criteria-based dependences for calculating the specific productivity and retention coefficient in the electromembrane separation of process solutions containing phosphate ions are proposed for use. The calculation of the economic efficiency of the technological scheme of wastewater treatment of RKS-Tambov using an electromembrane apparatus was carried out and its profitability was assessed. The profitability index will be 1.703, that is, more than 1, which is considered a profitable business. High rate and profitability of products. The payback period of the project is 2 years, which should be considered a good indicator, that is, after 2 years, the monetary resources invested in the project will return to economic circulation. The calculated payback period can presumably be reduced, since we have not indexed the price of the concentrate to inflation.
