What is a clarifier tank?
It is a tank built mechanically that is used to remove solids coming from sedimentation. Generally, a clarifier tank will have a built-in mechanism that can continually remove these solids. At the bottom of the tank, you can find concentrated impurities called sludge. Sludge and scum can both be monitored.
What is a clarifier launder?
Extending from the outer tank wall to the effluent weir, the clarifier launder protects the effluent trough, weir, and other parts of your clarifier launder from sunlight. Preventing windblown debris such as dust and leaves from entering clarifier launder channels. Controlling odors in the launder trough. and more.
What is the purpose of a clarifier?
A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and (or) thickening. Concentrated impurities, discharged from the bottom of the tank are known as sludge, while the particles that float to the surface of the liquid are called scum.
Where does sewage go and how is it treated?
Water leaving our homes generally goes either into a septic tank in the back yard where it seeps back into the ground, or is sent to a wastewater-treatment plant through a sewer system.

What are primary clarifiers?
Primary Clarifier. “Primary treatment” refers to the physical removal of solids from the wastewater by gravity. After preliminary treatment, the wastewater is introduced into a sedimentation tank or clarifier and the solids are allowed to settle to the bottom.
What is the main difference between primary and secondary clarifiers?
Typically, solids in the primary clarifier are inorganic whereas in a secondary clarifier, sludge is nearly 100 percent organic and thus can compact readily, making sludge far denser in a secondary unit than that of a primary system.

How is wastewater cleaned?
Most wastewater undergoes secondary treatment as well as primary treatment. The most common method is to sprinkle or trickle the water over a bed of sand or gravel. As the water filters downward, it is put into contact with oxygen and microorganisms, which work together to break down the organic matter in the water.
Do we drink sewage water?
But while this may be so, treated sewage water is not widely accepted as a drinking water source, largely due to the ‘gross’ factor. But the fact of the matter is that anyone who lives downstream from a wastewater treatment discharge point effectively drinks treated wastewater in some form or another.
What is removed from wastewater?
Pollutants in wastewater are removed, converted or broken down during the treatment process. The main by-product from wastewater treatment plants is sewage sludge which is usually treated in the same or another wastewater treatment plant. Biogas can be another by-product if anaerobic treatment processes are used.
