for the proposed nuclear reactor.'' A hybrid biological reactor (HBR) was developed which involved the introduction of a new phase of attached-biomass into a regular suspended-growth system (activated sludge process) by addition of carriers to the aeration tanks. A novel hybrid biological reactor which contained both suspended and attached-growth biomass was developed by introducing porous materials into a regular activated sludge unit and used for the treatment of domestic wastewater. A hybrid reactor is an

anaerobic digester Anaerobic digestion is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen. The process is used for industrial or domestic purposes to manage waste or to produce fuels. Much of the fermen ...

anaerobic filter Anaerobic means "living, active, occurring, or existing in the absence of free oxygen", as opposed to aerobic which means "living, active, or occurring only in the presence of oxygen." Anaerobic may also refer to: * Anaerobic adhesive, a bonding a ...

. This combination is an advanced form enabling improved solid retention time in the treatment of waste water. This waste water can be built up in the secondary chamber and must be removed daily or an explosion is imminent to occur.
