20130330707 | METHOD AND APPARATUS FOR DOSING AND SUPPLY OF NUTRIENTS DERIVED FROM DEWATERING PROCESSES - A method and apparatus to combine the dewatering filtrate, biomass, and nutrients into a single stream for ease of homogenization, and then separate the products and feeds to be reused. The system comprises of an automated control system which monitors the nutrient levels in the effluent in real time, as well as the current levels within the biomass, an ultrasonic wave generator for homogenization, and a centrifuge for separation of the useful products. The method and automated control are a result of thorough analysis and research in the area of microorganism cultivation in a variety of phototrophic, heterotrophic, and hybrid bioreactors. By combining waste effluent with process streams in a bio facility, the electrical and chemical demands of a treatment step are negated. | 12-12-2013 |
