Design, installation, start-up tests and commissioning of the aeration system in the biological treatment stage.

This is the first aeration system produced and installed by Aeration Systems Ltd. The biological stage consisted of two conventional activated sludge tanks, 48.0m long and 12.0m wide. Before the reconstruction, the aeration system consisted of perforated pipes, had low oxygen transfer efficiency and high energy consumption. The aeration system was upgraded using membrane diffusers, type DM-320, which provided high oxygen transfer efficiency. Energy savings in the range of 2.1 million KWh/year were realised.

94 000 population equivalent.
Number of DM-320 diffusers - 1800
