Applications of PRO₂ AIR Pre-PUR^®

PRO₂ AIR membrane tube diffusers – quality products from the NORRES stable – are mainly used for intermittent, fine-bubble, compressed air aeration (nitrification / denitrification). Our membrane material exhibits very good resistance to municipal wastewater according to the latest version of the DWA-M 115 Advisory Leaflet. Please ask NORRES for advice before using it in industrial wastewater.
