5 Things You Should Know About Sewage Treatment Plant

 

A sewage treatment plant works by circulating air to stimulate bacteria growth in order to break down sewage. The objective is to produce effluent that is significantly cleaner and more ecologically friendly. It works in a similar way to a traditional septic tank, but with a few significant changes. The sewage treatment plant can handle the waste of commercial buildings or a large number of private homes, depending on their size.

 The sewage treatment plant assists in the following procedures:

 1. Screening and Pumping

Objects such as rags, wood pieces, plastics, and grease are removed from the entering wastewater using screening machinery. The extracted debris is cleaned and pressed before being disposed of in a landfill. The grit-removal process is next performed on the filtered wastewater.

 2. Grit Removal and Primary Settling

Heavy yet fine debris like sand and gravel is removed from the effluent in this stage. This waste is also thrown away at a landfill. Large circular tanks called clarifiers are used to remove the material, which will settle, but at a slower rate than in step two. 

 The settled material, referred to as primary sludge, is pushed out of the bottom of the tank, while the wastewater emerges from the top. Floating debris, such as grease, is skimmed off the top and delivered to digesters together with the settled material. Chemicals are also used at this point to eliminate phosphorus.

 3. Aeration

The wastewater receives the majority of its treatment in this stage. The contaminants are eaten by microorganisms and converted into cell tissue, water, and nitrogen through biological breakdown. The biological activity that happens in this stage is quite similar to that which occurs at the bottom of lakes and rivers, although the deterioration takes years in these places.

 4. Filtration

This stage polishes the cleared effluent by filtering it through the 10-micron polyester medium. The material caught on the disc filters' surfaces is backwashed and sent to the plant's head for treatment on a regular basis.

 5. Oxygen Uptake

If necessary, the treated water is aerated to bring the dissolved oxygen content up to the allowed level. After this, the treated water is discharged into the Oconomowoc River via the effluent outfall. The water released into the river must fulfill the DNR's strict criteria. Pollution reduction is kept at 98 percent or above.

 A softening plant is also necessary for complete treatment. A water softening plant lowers the concentration of dissolved calcium, magnesium, manganese, and ferrous iron ions in hard water.

Hyper Filteration has created portable STPs, which are ready-to-install STP plants that generate highly filtered water that may be discharged or used for drinking and distribution.
