and his team have been at the forefront of bioreactor technology development for decades. The innovation in the EBR technology is apparent and addresses key industry concerns,” he said. “This agreement is another step in our drive to
push bioreactor technology to meet new challenges for treatment efficiency and cost-effectiveness. The goal here is first to be able to develop better solutions tailored to groundwater and wastewater treatment applications in mining, power, chemical and refining facilities – and potentially to develop revolutionary, next-step bioreactor technology,” he continued. Envirogen’s FBR is a fixed-film bioreactor in which
biological media is suspended, or fluidised, within the reactor vessel by the upward flow of water through the system. High concentrations of biomass, its plug- flow characteristics and tall beds minimise bioreactor footprint and shorten retention times. They offer steady- state performance, without the need for backwashing and are tolerant of high feed total dissolved and suspended solids and metals. Inotec’s EBR provides electrons to microbes in
reactor environments using low DC voltage potential (1-3 volts) and mA current in configurations that provide an electron density gradient or a controlled electron density. The provided electrons result in increased microbial contaminant transformation kinetics, reduced retention times, and reductions in
the amount of nutrients and chemicals required for contaminant removal. D Jack Adams, president of Inotec cited Envirogen’s
experience in deploying over 60 FBRs for groundwater and wastewater treatment as an indication of the company’s leadership in the field. “The Envirogen team are pioneers in fluidised bed bioreactor technology for water treatment. Development of hybrid bioreactors, like an electro-biochemical fluidised bed reactor technology, holds considerable potential for more economical and more effective water treatment. We look forward to working with Dave Enegess and the Envirogen team to apply the synergistic benefits of our combined technologies and to continue advancing the science and performance of bioreactor technology.” Meanwhile Siemens continues its development of membrane bioreactor (MBR) systems. “The need to recycle wastewater and stricter
environmental regulations make an MBR system a viable solution for current and future wastewater treatment. We make MBRs for large municipal wastewater applications that can be fit into concrete tanks, package plants for smaller flows, new developments and hotels as well as a system developed for the petroleum industry to meet most refinery standards,” says the company. For example, Xpress MBR package plants are
designed for applications from 25,000 gallons/day (gpd)
