A Digester is a vessel that provides for the process of anerobic digestion. It is commonly made of concrete and houses anerobic bacteria. Sewerage sludge is normally pumped in at regular intervals to maintain a food supply for the population of anerobic bacteria. Anaerobic digestion is a process in which microorganisms break down biodegradable material in the absence of oxygen. The process is widely used to treat wastewater sludges and organic wastes because it provides volume and mass reduction of the input material. A conical floor can be included in the digester design to facilitate product removal and cleaning. Some form of mixing equipment is also normally used to promote the digestion process.
Digesters are typically found at Wastewater Treatment Plants.
Digesters are typically made up of some or all of the following components:
- Dust Filters
- Flame Arresters
- Floating Digester Lids
- Gas Mixers
- Motor Starters
- Slide Rails
- Swivel Joints
