How Waste Stabilazation Pond Perform A Sewage Treatment

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,

How do sewage ponds work?

There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment.Dec 6, 2018

What is pond sewage treatment?

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

What are the 8 steps of sewage treatment?

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.

How do settling ponds contribute to the removal of solid waste during wastewater treatment?

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.

What is the role of aerated lagoons and stabilization ponds in the treatment of wastewater engineering?

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.

How stabilization ponds are used for wastewater treatment?

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.
