Background: Water and wastewater treatments consume 3-4% of energy while 60% of energy used at the wastewater treatment plant is dedicated to aeration in the activated sludge process. This novel bio-granule called oxygenic bio-granule proposes to transform wastewater treatment facilities into water resource recovery facilities. The oxygenic bio-granule results from the conversion of activated sludge under photochemical reactions. It is naturally formed and is composed of algae and bacteria within one granular biomass.

UET products are based on a mathematical algorithm in the field of chemical engineering for the production of a process unit composed of a green reactor and settler (Green Machine). The calculated amount of scale corrosion products and bio life are being produced in the UET’s reactor and settled in the UET’s settler. The driving force for the reactor is partial electrolysis of the water. The process unit is tailored to specifications manufactured and delivered to the customer including the highest level of engineering and technical support.

Techase has developed a Special Multi-plate Screw Press which is adaptable to deal with sludge from a variety of industries such as petro chemistry paper amyloid chemical blue-green algae pectin wastewater inorganic material and so on. For instance if the filter press is to be used to dewater sludge contaminated with blue-green algae it is fitted with special shafts for the algae and special flocculants.

The EPA’s National Risk Management Research Laboratory (Dr. Albert Venosa) in collaboration with the University of Cincinnati (Dr. Makram Suidan) have developed a gravity-flow Biomass Concentrator Reactor (BCR) for biological water treatment. The BCR design encompasses an aeration chamber housing a high surface area porous polyethylene membrane system that retains all of the biomass within the aeration chamber. Its simple operation and low maintenance requirements may render it economically more feasible than other water treatment technologies.
