Authors: Pruk Aggarangsi, PhD (Energy Research and Development Institute- Nakornping, Chiang Mai University, Thailand)
In Thailand, there are numerous pig farms which must treat the pig effluent in order to meet the standards set by the Pollution Control Department (PCD) of Thailand's Ministry of Natural Resources and Environment (MNRE) (MNRE, 2005). This case study illustrates the use of Upward-flow Anaerobic Sludge Blanket (UASB) reactors as adopted by one pig farm, the Sam Pran Pig Farm, in Nakhon Pathom Province, located approximately 40 miles (65 km) southwest of Bangkok.
