The Technology

MSR-Technology™ “Microbial-Soil-Reed Beds” is providing world-leading treatment of industrial wastewaters including hydrocarbons from numerous producing oil fields. All stable processes for treatment of organic contaminants involve the degradation of common and complex compounds with the use of microbial action in either anaerobic or aerobic conditions. Organic wastes provide nutrient for microbial growth.
