Aeration system
Aeration system "AKEMO"
The performance and accurate function of a waste water treatment plant with a biological aeration step depends on the correct choice of an aeration system. Aeration in the equalization tank is necessary in order to avoid anoxia as well as sedimentation. In the aeration tank, aeration is required to facilitate bacterial growth and performance. Only if a sufficient amount of oxygen is provided through the aeration system in the aeration tank, can the bacteria degrade the organic pollutants and promote the nitrification of the ammoniac nitrogen.
“AKEMO” is a static aeration system installed in equalization tanks, in aeration-nitrification tanks as well as in aerobic digestion tanks. Its function involves the dynamic mixing of water with air under low pressure in a specially shaped head and diffusion of the former mixture in the aeration tank.
The benefits of the “AKEMO” aeration system over other types of aeration are:
1. Water droplets are not produced
2. Foam is not produced.
3. No clogging is observed.
3. If foam is already present in the aeration tank its function is not influenced.
4. Does not require maintenance
5. Its function remains stable over time
AKEMOs’ operation guarantees stable and high yield in terms of air supply. Typical yield values are over 1,8 Kg O2 / kWh and can even reach 2,2 Kg O2 / kWh with the addition of the static mixer STEMO (optional). The “AKEMO” unit can be installed on the ground or can float depending upon requirements. The construction material varies.
The “AKEMO” unit is composed of two parts:
1. The system that receives air from the blowers and distributes it thereafter in to the heads
2. The water-air mixing heads
