Design, construction and start-up tests of the aeration system of the two stage biological treatment plant – extended aeration activated sludge plant and SBRs.

The design of the landfil site included a series of installations, part of which was the wastewater treatment plant for the leachate as well as liquors from the solid waste bio-mechanical treatment and composting plants. The wastewater is highly pollutted and requires biological treatment in two stages – the first stage includes extended aeration activated sludge plant and contains 424 diffusers; the second stage consists of four SBRs, where 240 diffusers are installed.

Total numbеr of DM-320A Diffusers – 664
