Aeration Tips To Remember When Treating Wastewater

26 March 2020

Industrial wastewater aeration uses oxygen to assist bacteria in breaking down wastewater. Aeration increases the dissolved oxygen level of your wastewater and also mixes the wastewater so that it can be treated more easily. Aerobic microorganisms consume the pollutants found in the wastewater. There are several methods that can be used to improve this process with wastewater aeration equipment. 

Follow Regulations

Know the regulations regarding wastewater discharge. Regulations govern how many nutrients may be discharged with wastewater. The most common way to remove nutrients from wastewater is to use an activated sludge treatment. 

Distribute Oxygen Evenly

For wastewater aeration equipment to be effective, you'll need to make sure that the air is evenly distributed. Perform a regular assessment of the air so that you may treat dead zones. When the oxygen is properly distributed, you won't have to worry about sedimentation and stratification as much.

Replace Technology Flow Meters

If you are using old aeration equipment, make sure to replace the technology flow meters. Doing so will improve performance, reduce maintenance, and allow you to save money on energy costs. You may also want to consider replacing the wastewater aeration equipment with a newer and more efficient model.

Place the Aerator at the Right Depth

The mechanical aerator needs to be placed at the right depth so that it can function properly. When the aerator is at the right depth, you'll be able to maximize mixing while minimizing the amperage required to do so. 

Perform Regular Maintenance

Perform regular maintenance on your aeration equipment to ensure that it functions properly. Otherwise, the equipment might be subjected to excess vibrations and may fail. Make sure that the filters aren't clogged. Check seals, lubricate bearings, and check air inlets. Your sub-surface aeration equipment will need to be maintained as well. Make sure the diffusers are not clogged, broken, or damaged. Inspect motors to ensure that they don't have leaks. Remove any debris that has collected.

To ensure that the aerator is functioning properly, routinely test oxygen profiles. Dissolved oxygen-control sensors and stage unit operation can help you ensure that enough oxygen is being injected into your wastewater. 

You'll only be able to accurately measure your water oxygen levels if you properly maintain the probes that are used to perform readings. Therefore, it's important to clean, calibrate, and repair any probes. Double-check that the aeration readings are accurate. Make sure that the aeration readings are consistent. After taking all of these steps, you'll be able to properly aerate wastewater.
