How much does a compact sewage treatment plant cost Archives - Water Treatment Plants

January 14, 2023

When wastewater contaminants are put into various processes of a compact sewage treatment plant, they lose their characteristics and can be restored to their stateless condition by being dumped into the ground, ditches, streams, etc. Adequate treatment to achieve the decontamination of these waters is a biological treatment, in which they go through a natural transformation process called digestion. Through this process, there are several biochemical reactions that result in the breakdown of organic substances into other components.

The facility must have specific qualities that enable microorganisms to carry out their functions in all waters to be treated without interruption in order for this procedure to take place under ideal circumstances. Our family of small wastewater treatment plants prioritizes adaptability so that it can handle a range of flow rates and operating circumstances.

Let’s learn more about the compact sewage treatment plant…

Process description of compact sewage treatment plant:

Pretreatment, biological treatment, sedimentation, and final effluent discharge parameters make up the treatment process. The treatment’s phases are as follows:

Pumping to a screen


Its goal is to remove particulates from the water so that the facility won’t silt up or have mechanical issues. To prevent wastewater biological treatment by pumping being delivered by gravity, a screen will be placed at the top of the biological treatment tank.

Biological treatment:

The biological treatment is carried out in a tank with an anaerobe chamber and an aerobic chamber.

The Anaerobe Chamber:

Without atomic oxygen, this causes the breakdown of both organic and inorganic materials. In the anoxia chamber, organic matter that is soluble and colloidal is converted to volatile acids, which are then converted to methane and carbon dioxide. Methane and acid fermentation are both produced by many kinds of bacteria.

Because facultative heterotrophic bacteria do denitrification, they employ BOD as a source of organic carbon and energy for synthesis as well as nitrate (NO3-) as a source of oxygen.

Aerobic Chamber:

The proportion of biological oxygen demand to chemical oxygen demand is used to calculate wastewater’s biodegradability. This score indicates whether the chemical being purified is likely to be filtered by biological degradation or not.

The most popular method of biological treatment utilized in wastewater treatment is known as activated sludge. It is necessary to purify the effluent in order to encourage the growth of a bacterial culture that is spread in an aerated tank as floc (activated sludge).

In order to satisfy the oxygen needs of aerobic bacteria used in wastewater treatment, aeration is used to dissolve the oxygen in the mixed liquor. In its initial stage, aerobic biological treatment of wastewater results in the growth of bacteria that congregate in films or flocs and are retained and fed on by physical activity or physical-chemical pollution. In a subsequent phase, the resulting sludge is often separated by sedimentation.

At this step of purification, the bacteria are responsible for cleaning. Their meal consists of biological materials, which worries humans. Colonize into biological flocs, which are colonies where several living bacterial species coexist with the food. In order to function, bacteria need oxygen to breathe.

 Settling chambers:

Water flows by gravity to the clarifier lamella, which is often positioned on the same module as the biological treatment, after biological treatment in the settling chamber. Lamellar decanters have the benefit of requiring very little installation space and no energy. The flow created by tilted lamellae makes it easier to separate clean water from the muck. Because the microorganisms have a thick structure and form quickly settling flocs, sedimentation is brought on by gravity. While the mud sediments are deposited at the bottom of the decanter’s funnel, the cleared water gently rises between the lamellae to reach the treated water outlet ports.
