Faced with treating 12 tons of effluent per day, the WWTP in Jilin Province selected Porvair's proven BioVyon disc diffusers to provide a uniform distribution of air bubbles with good oxygen transfer in the activated sludge process process. Chosen for its low operating costs and high oxygenation transfer efficiency (4-6kg Oxygen /kWh) the Porvair BioVyon™ disc diffuser is composed of po...
