New Design Guidelines for Anaerobic Ponds
20 Pages
Author(s): Robyn Tucker, FSA Consulting
The main objective of effluent treatment is to remove organic matter and nutrients from raw piggery effluent. Most primary effluent treatment ponds at piggeries are anaerobic, because the high organic loading that they experience consumes any dissolved oxygen to exhaustion. Anaerobic ponds are a popular treatment option as they are simple to build and operate, and provide for effluent and sludge storage. Well-designed, properly-managed anaerobic ponds also provide good effluent treatment without odour nuisance or adverse impacts to water resources.
