Engineers consider a range of factors — including the waste to be treated and the desired outcome — when designing an AD system Anaerobic digestion (AD) is a well-established technology for the treatment of organic waste streams. It harnesses the power of microorganisms in an oxygen-free environment to decompose organic matter, generating renewable biomethane as a byproduct and ...
Anaergia Services (UTS) Greenlane Biogas (Flotech) NIPSCO (Pipeline) Cummins Westport (Engines) PROJECT SUMMARY An anaerobic digester built in 2009 — using bacteria in an oxygen-free environment to convert organic waste to renewable compressed natural gas (R-CNG) — processes 500,000 gals/day of liquid manure ...
Production of biogas from different organic materials is a most interesting source of renewable energy. The biomethane potential (BMP) of these materials has to be determined to get insight in design parameters for anaerobic digesters. Although several norms and guidelines for BMP tests exist, inter-laboratory tests regularly show high variability of BMPs for the same substrate. A workshop ...
1. Introduction The Moosburg wastewater treatment plant has one 634,008 gallons anaerobic digester, which was designed to process a maximum 23,775 gallons/day of activated sludge at 3.5% solids. The AD is currently processing 17,170 gallons/day of sludge and producing 39decatherms/day of energy from biogas. The operators would like to better utilize their anaerobic digester to achieve energy ...
New Zealand has over 1000 anaerobic waste stabilisation ponds treating wastewater from farms and industry. Traditional anaerobic ponds were not designed to optimise anaerobic digestion to produce biogas and are therefore uncovered, releasing biogas to the atmosphere, which can cause odour problems and contributes to GHG emissions. The biogas production and treatment performance of an anaerobic ...
Dublin’s Ringsend Wastewater Treatment Works was also the winner of the 2004 CIWEM Ken Roberts Award for Technical Innovation in the Water Industry. Conventional design of anaerobic digestion would have called for about 36,000 m3 of digestion capacity and at a VS destruction of 50% VS. The Dublin digestion plant has a ...
ABSTRACT The District of Columbia Water and Sewer Authority (DC WASA) has decided to incorporate thermal-hydrolysis pretreatment in conjunction with mesophillic anaerobic digestion as the backbone of a long-term biosolids treatment plan to produce Class A biosolids. The Authority has been lime stabilizing their raw solids from the Blue Plains Plant for many years, transporting them to the State ...
