Tip #1. Make improvement in the wastewater treatment process
When you stick to the old methods of treatment and suffering from the bad odour in the Sewage treatment plants makes no sense. It’s time to make improvements in the treatment process. You need to take action to upgrade to new technology which effectively maintains a balance in the microbial consortium i.e., the microbial cell count and cell viability. Whcih helps in efficient treatment and elimination of bad odor.
Tip #2. Empty the solids collected in the bar screen chamber regularly
You need to remove the floating matter from the waste stream in the bar screen chamber. Over a period of time as solids accumulate, it starts producing bad odor at the entrance of the treatment plant. It is advisable to empty at least once a week to avoid bad smell.
Tip #3. Provide continuous aeration in the aeration tank
Bad odour in treatment Plants is usually associated with the aeration. Odour is generated as a result of an anaerobic or “septic” condition. This occurs because of limited oxygen transfer to the wastewater . Low dissolved oxygen coupled with rising temperatures leads to an increase in anoxic zones at the bottom of wastewater aeration basins. Anaerobic digestion releases sulphur dioxide, along with a variety of other noxious gases that are the causes of wastewater odor. Continuous oxygen supply ensures that the aerobic bacteria have the oxygen they need to aerobically digest BOD.
Tip #4. Design treatment plant to handle actual influent waste characteristics
Design wastewater treatment plant to treat the actual waste characteristics is very important for treatment to happen and to avoid foul odor as well. When the treatment plant is not capable to handle the influent characteristics. It starts producing foul odor due to insufficient aeration, not enough retention time for the wastewater to be in contact with the microorganisms for destruction of organics. Hence it is viable to design the treatment unit to handle the influent waste and eliminate odor.
