Extended aeration is a wastewater treatment that reduces sludge production and can accommodate varying levels of waste generation. The process involves screening, comminuting, and aerating the waste to encourage the growth of aerobic bacteria. The system must comply with regional regulations and be properly maintained to avoid environmental hazards.
Extended aeration is a wastewater treatment treatment designed to reduce the volume of sludge produced. It can work well for small business waste treatment or other facilities with a low volume of waste generation and can also be beneficial for facilities with varying occupancy. The system can expand and contract to accommodate different levels of waste generation over time, while remaining functional. Numerous manufacturers produce extensive vent systems and can be installed by many plumbers and septic experts.
The system begins with a screen to trap items that shouldn’t be moving in the processing tank, such as socks and other debris that may have ended up in the waste stream. Flowable mixtures can be comminuted or otherwise processed to break them up into a more uniform suspension of solids and liquids. These move to a large tank where they are aerated to encourage the growth of aerobic bacteria which can eat the biological waste inside. This is similar to the system used with conventional wastewater treatment, including recycling sludge from the bottom of the tank to keep the organisms inside thriving.
In the extended aeration process, however, the mix is aerated longer than usual. This allows the organisms to continue to grow and feed, breaking down the sludge. As a result, less overall sludge is produced, limiting the volume of material produced by the system. Treated waste from an extended aeration tank can be transferred to the next stage, allowing for further treatment before being released or collected by a specialist wastewater treatment company.
Depending on regional regulations, there may be specific requirements on wastewater treatment plants and septic systems. These can determine whether extended aeration is permitted as a treatment process and whether additional steps need to be taken to comply with clean water laws. It is important to ensure that systems comply with the law, otherwise people may face fines or may find it difficult to sell properties, because buyers may not want to buy a property with a sewage system that does not comply with building codes.
As with other wastewater treatment methods, extended aeration relies on a properly maintained system. Owners of such systems should ensure that they are functioning properly by regularly checking for common problems. If they fail to maintain the system, it may malfunction, potentially endangering the local environment. For example, the balance of bacteria in the sludge may be too low, so they can’t fully consume it, creating a high volume of raw sludge that shouldn’t be released into the surrounding environment.
