There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment. In some applications, more advanced treatment is required, known as quaternary water treatment.
What is the difference between waste water and sewage water?
The terms 'wastewater' and 'sewage' are regularly used interchangeably, however there are differences between both. In fact, 'sewage' is considered a subset of wastewater.

How does STP plant work?
Using internal mechanisms, a sewage treatment plant works by breaking down solid waste to produce a cleaner, more environmentally friendly effluent. Wastewater and sewage are supplied to the primary tank, where the solids and liquids disperse. The resulting liquor flows into the biozone chamber.
What is the difference between water treatment plant and wastewater treatment plant?
Water Treatment Plants (WTP) generally are smaller operations than Wastewater Treatment Plants WWTP) because of the water quality coming in. WTPs pull water from a local river, lake or well. This water is generally clean (compared to sewage!) and just need a bit of cleaning and disinfection.

Can a plant degrade a neighborhood?
The plant should not degrade the neighborhood. This can be accomplished in a number of ways. The buildings associated with the project should match the buildings in the surrounding neighborhood—both architecturally and in materials selection. Sometimes, the fencing can be an eye sore.
Is membrane bioreactor better than activated sludge?
For example, membrane bioreactors (MBR), by virtue of their smaller footprint, may be a better treatment process than conventional activated sludge. In small size plants, with MBRs, it may be possible to eliminate primary clarifiers, which often generate more odors than other processes at the plant.
