Different Types Of Filters Used In The Biological Treatment Of Wastewater

Wastewater treatment is the process of recycling and treating sewerage water for re-use. Untreated water comprises a high degree of contamination, bacterial and dirt elements that could ruin or induce reserves. The planet is already facing a dearth of new water drinking reservations and for that reason, the untreated has to be treated in order to make it re-usable.

There are a lot of ways that industrial Wastewater treatment system (which is also known as “ระบบบําบัดน้ำเสีย” in the Thai language) is now establishing efficient techniques to take care of home and industrial wastewater distinctively. Here are a few of the general ways it’s treated and how they help the environment.

Primary Treatment

Wastewater treatment is broken down into different processes, based on the industrial and domestic character of water. In the principal level, floating solids and items are removed. After the sewerage is transferred out of the sewers it enters a barrack that holds back strong items and allows it to flow through a different container where parasitic (sands, stones) are eliminated.






The solids that are removed are then managed by a sedimentation process where the solids are ready for the landfill. It’s then disinfected to kill off pathogenic bacteria together with clearing excess chlorine. It’s then passed out to the sea, while the sludge that remains back in the container is used as fertilizers.

Secondary Treatment

The principal level is the conventional handling, according to the Environmental Protection Agency (EPA), it’s insufficient. The bacteria present can still be harmful to the environment; hence the sewerage is provided secondary treatment, which can be biological. Where the main level only removes 50% of the topic, secondary removes 85% of it.

Advanced Treatment

It’s simple to treat off national sewerage, but in the event of industrial sewerage, there need to be advanced procedures to clear heavy metals and toxic substances. This is achieved through complex processes like microfiltration, carbon adsorption, and various procedures of evaporation together with chemical precipitation
