Contact oxidation filler

Biological contact oxidation method is an efficient water treatment process that mainly uses biofilms attached to carriers (contact oxidation fillers) to purify organic wastewater. It is a biofilm method with the characteristics of activated sludge method, which combines the advantages of both activated sludge method and biofilm method. Under biochemical conditions, good economic benefits have been achieved in the treatment of industrial wastewater, aquaculture wastewater, and domestic wastewater. This process is widely used in sewage treatment systems in various industries due to its high efficiency, energy saving, small footprint, impact load resistance, and convenient operation and management.
