Pond systems stabilize organic material through natural processes involving sunlight, water, nutrients, algae, atmospheric oxygen and bacterial action. Organic matter in the wastewater is broken down by aerobic bacteria and oxygen found in the pond.Sep 30, 2011,
There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment.Dec 6, 2018
A sewage lagoon is a large pond into which the sewage or effluent from the sewage system flows. ... The sewage and effluent are broken down by germs in the lagoon. The sun and wind play an important role in the working of the lagoon. They provide light, warmth and oxygen to the water.Jan 2, 2019
A treatment pond is intended to provide wastewater treatment to achieve a certain effluent quality. Ponds are depressions holding water confined by earthen structures. ... Anaerobic lagoons are waste stabilization ponds providing habitat for anaerobic microorganisms.
Treatment mechanisms involve the removal of suspended solids by the sedimentation process. Typically, domestic wastewater particulates BOD in a range of 40-60% (Alexiou & Mara, 2003). Anaerobic ponds reduce microorganisms by sludge formation and the release of ammonia into the air.
An aerated lagoon (or aerated pond) is a simple wastewater treatment system consisting of a pond with artificial aeration to promote the biological oxidation of wastewaters.
The first pond biome in a series of stabilization ponds digests the putrescible solids suspended in the wastewater being treated. Anaerobic ponds allow solids to settle down at the bottom as sludge. This settling removes a portion of the particulate organic material.
