What is a Clarifier in a Wastewater Treatment Plant?

Technology

The systematic management of wastewater from industries and homes is essential from the standpoint of human health. Generally, it happens in wastewater treatment plants wherein specialists separate suspended solids from impure water while treating it.

Suspended particles in wastewater can be of two types. Particles floating on the surface are known as scum, whereas the ones below it is called sludge. Removing both can be tricky, especially by using standard procedures. As a result, a dedicated process is necessary to achieve desirable outcomes. The technical term for this process is sedimentation.

The principal of gravity plays a vital role in the purification of wastewater through sedimentation. It settles contaminants and helps liberate clean water. Poly-electrolyte and coagulants, coupled with scraper blades, assist in the execution of this task. Together, they help accumulate suspended particles and scum in a settling tank called a clarifier. It consists of mechanical means to remove solids that gather in it.

Read on to know more about it and its different versions.

Different kinds of clarifiers

Clarifiers in wastewater plants are available in different designs. Apart from primary and secondary clarifiers, they also appear n different shapes. Prominent among them include the ones that take either a circular or a rectangular shape. Also, they can be solid contact clarifier.

Primary and secondary clarifiers

Primary and secondary purifiers help remove impurities from wastewater. Floating and settleable solid wastes are responsible for the pollution of water. Removing them is necessary to reduce the biological oxygen demand (BOD). Primary clarifiers take care of this requirement in wastewater treatment plants.

After the primary treatment of wastewater, the next step is to release clean water and thicken and clarify the collected waste. Secondary clarifiers help in the execution of this step. Instead of any chemical or substance, it makes use of microbes for separating wastes from wastewater and make it fit for use.

The functioning of both the versions of clarifiers helps achieve the objective of purifying water plus disposing of the waste with the safety procedure.

Miniscule microbes play a vital role in the purification of wastewater at a wastewater treatment plant. Apart from aerobic and anaerobic methods, the combination of both can be handy for achieving the desired objectives.

How microorganisms play an important role in the functioning of the secondary clarifier

Polluted water consists of excessive nutrients and organic waste. One way to clarify it is to separate both these forms of impurities from it. Biological treatment is a useful option for this purpose. In this approach of cleaning water, microorganisms not only absorb nutrients but also break down organic waste.

Wastewater is harmful both to the environment and human health. The growth of microorganisms in large quantities proves to be useful for the purification of water both in the presence of oxygen as well as without it.

Cleanmaxx STP – an outstanding sewage treatment solution

Clarifiers play a vital role in the treatment of wastewater. Apart from the purification of water, they also treat biomass at the secondary level. Effective biological treatment is possible only with a secondary clarifier that works efficiently.

In a loaded system, the organic matter may increase and the concentration of dissolved oxygen may reduce. It may interfere with the functioning of a secondary clarifier and affect the outcome.

Cleanmaxx STP by Organica Biotech reinforces the ability of a secondary clarifier to perform its function without any compromise. As a result, a secondary clarifier gives the desired output. Its effective formulation makes it the ultimate solution to improve the efficiency of sewage solutions.
