Advanced Wastewater Treatment
Extended Aeration
See Solutions’ Extended Aeration Process, an advanced Activated Sludge system, delivers superior wastewater treatment. With a 24-hour aeration cycle and a 4-hour settling tank, it biologically removes biodegradable organic wastes under optimal aerobic conditions, ensuring high efficiency.
Our diffused aeration technology provides flexible oxygenation, fostering aerobic bacteria to thrive and effectively reduce Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS). Settled solids are swiftly recycled, producing clear effluent for reuse or safe discharge into streams.
Advantages
Advantages Of Extended Aeration System
- Extended aeration processes are often better at handling organic loading and flow fluctuations, as there is a greater detention time for the nutrients to be assimilated by microbes
- Systems are odor free, can be installed in most locationsand can be landscaped to match the surrounding area
- Extended aeration systems have a relatively low sludge yield due to long sludge ages, can be designed to provide nitrification, and do not require a primary clarifier
Disadvantages
Disadvantages Of Extended Aeration System
- Extended aeration plants do not achieve denitrification or phosphorus removal without additional unit processes
- Flexibility is limited to adapt to changing effluent requirements resulting from regulatory changes
- A longer aeration period and hence requires more energy
- Skilled personnel are required for the operation and control of return sludge and maintenance of MLSS concentration in the aeration tank
