Waste Stabilization Ponds

Waste Stabilization Ponds are now assessed as a method of first choice for waste water treatment in most countries around the world. It’s widely used by rural communities. In warmer climate, most of the waste is handled using waste stabilization ponds method.

Waste Stabilization Ponds

The processing of this method is considered as an ideal way to use natural processes to improve better effluent. Waste stabilization ponds is often known as oxidation ponds to maintain the micro organism used for biological waste water treatment plants and to convert organic compounds become more stable effluent.

Stabilization ponds are used for both domestic and industrial waste water treatment. It can be an alternative with little process cost. But need wider area for the ponds.

Anaerobic and facultative ponds are two types of stabilization ponds. Anaerobic ponds is a pool which receives high organic load in general BOD/m3 100 gr. This works very well in warm weather and have lived a relatively short time.

What’s happening in anaerobic pond? There are some process in this pond such as the separation of dissolved solids from the sludge material, further separation of organic material, the reduction of biodegradable organic material, retaining the unprocessed material and solids that are not degraded in the form of sludge, and partial processing of the effluent before processed further.

While for the facultative pond is a pool for the relatively lower expenses. Here, the temperature is maintained, so that algae remain alive as an oxygen supplier for the bacteria. Facultative ponds remove the smell and the ability to kill pathogenic microorganism. Facultative pond has its advantages: treating effluent from an anaerobic process, reduce the residual organic solids that existed at the surface of the pool, reduce disease-carrying microorganisms, produce a worthy treated water discharged in water bodies.
