Landustrie realized a large part of the newly built sewage treatment plant Hilversum-East (91,000 PE), including a.o. screens, filters, pumps, pipework, sludge scrapers and aeration equipment. It is worth mentioning that Aerostrip® bubble aeration is used in the aeration tank. A total of 868 Austrian-made diffusers have been installed here. The primary settling tank uses a WesTech drive unit. Landustrie has been marketing these central drives since 2004.
