From the experience with conventional treatment plants, people have accepted that bad odor is a part of STPs and it is common
It is true that in most of the conventional treatment plants, clients experience the issue of bad odor and they have accepted that bad odor is a part of the Sewage treatment plant. During our visit to one of the conventional treatment plants, we asked the maintenance engineer how the plant is performing? The answer was everything is good, the plant is performing very well but there is some common odor. It is high time and very important to change the mindset of the people that it is not common or ok to have a bad odor in the STPs.
The reason for the treatment plant producing bad odor is due to improper treatment in the aeration tank because of not maintaining the desired level of microbial consortium i.e., microbial cell count and cell viability. When the microbial consortium is not maintained properly, there will be no biological treatment happening, and when the biological treatment is not happening, the treatment plant produces a bad odor. A good working biological system will not produce odor.
Every treatment plant produces odor, wastewater treatment plant means where there is waste, obviously, it produces odor
Builders and owners of the property have seen a maximum number of treatment plants installed based on conventional technology produces bad odor, so there is a mindset that sewage treatment plant will produce odor and wastewater treatment plant means where there is waste, obviously, it produces odor.
Now, things are not the same, and a lot of research is going on and new technologies for treating wastewater are evolving and it’s high time to change the mindset and be the change that wastewater treatment plant can be operated without producing a bad odor. At OxyO, treatment plants are designed to maintain a balance in the microbial activity resulting in a fully digested sludge with no bad odor in the treatment plant. With the utilization of biofilm for the treatment, the bad odor has been eliminated.
