DIGESTER / WWTP BIO GAS RECOVERY
May 3, 2012
Millions of gallons of sewer water is returned to Waste Water Treatment Plants (WWTP) for cleaning. The sewer water comes from households as well as commercial & industrial facilities.
The solids from the waste water treatment process are sent to Digesters, which break down the solids to produce Anaerobic Digester Gas. The gas typically contains 60% methane, a recoverable and renewable source of energy. Most of the remaining gas is CO2, a potential source for fertilizer.
It’s is a valuable source of “GREEN ENERGY”; however, it’s hot (90 to 110 0F), humid (80-100 %) and dirty; and, its produced at a very low pressure (8” – 20” WC).
Untreated, the gas is not suitable for power generation, because, it damages piping & equipment coming in contact with it. Its most troublesome contaminants are – Moisture, Siloxanes and Sulfur compounds. The gas shall be cleaned, dried & compressed for a gen-set, turbine or boiler.
The gas recovery eliminates harmful emissions to atmosphere, provides a renewable domestic energy source, and, earns EPA credits for WWTP.
For proper selection and sizing of equipment, consult factory. PIONEER systems are available with or without PLC (AB/ SIEMENS/ GE), with your choice of controls. Non-standard equipment is our specialty.
