In August 2014, Proffico Sp. z o. o. and Instal Warszawa SA (acting as the general contractor) signed an implementation agreement for the delivery and installation of a fine-bubble aeration system for the sewage treatment plant in Morąg. As part of this task, Proffico will deliver and install Sanitaire Silver II type membrane disc diffusers and Flygt slow-speed mixers in the activated sludge chambers. The aeration installation will be additionally equipped with a special supporting structure ensuring its possible removal without the need to empty the reactor.
