Description: Today, there are no environmental technologies that ensure the purification of industrial wastewater from a wide range of metals. Any biotechnology is capable of purifying wastewater from those concentrations of metals that make up the wastewater. But microbial biotechnology, developed by the Ukrainian institute, is capable of this. It allows in a short time to purify industrial metal-containing wastewater using a granular microbial preparation. The technology has a wide spectrum of action and can be applied to purify waters from chromium, copper, mercury and other toxic metals at any concentration thereof, as well as to obtain a valuable concentrate of metals and water. Its active basis is a granular microbial preparation containing live microorganisms. The granules of the preparation are stable in water and autonomous in operation. When the wastewater passes through the layer of the preparation, the metals are completely removed from the wastewater. This separates the concentrate of valuable non-ferrous metals. Microbes used to purify metal-containing waters are completely safe for humans and animals. Biotechnology has passed an industrial test at the Kiev Municipal Engineering Plant. With the help of 5 kg of a granular microbial preparation, 2 tons of industrial chromate-containing wastewater from the galvanic shop were purified. A useful product, a technical abrasive, was obtained by burning a spent preparation. Applications: mining plants for the extraction of precious metals (gold, silver), electroplating plants, metallurgical enterprises.
Expected result of the investment: Implementation of the proposed biotechnology at the customer’s industrial wastewater to be treated.
Contribution of the organization proposing the project: Created experimental-industrial technology; agreed pilot industrial operational regulations; biotechnology has passed an industrial test at the Kyiv Municipal Engineering Plant.
Expected investment: Manufacturing and testing on the customer’s waters will cost $ 200,000, and rework costs $ 100-200,000.
