Aerobic Digester

quick overview :

Aerobic Digester

Specification:

• A 10-litre bench mounted aerobic reactor, complete with peristaltic feed pump, air compressor and temperature control system.
• Dissolved oxygen and pH probes and meters are included.
• The reactor consists of a cylindrical porous liner held in position with sealing rings between the lid and the base to facilitate removal for cleaning and replacement.
• Suspended solids are thus held within the reactor volume, whilst treated water permeates through the porous liner into an outer annular exit chamber.
• The water level is maintained by an adjustable constant head overflow device.
• This digester system is designed to operate safely and reproducibly for periods of many days.
• The equipment is mounted on a moulded plastic base, equipped with an internally moulded drain channel, designed to cope with spillages and wash-down water.
