|NORRES PRO2 AIR Pre-PUR® tear propagation strength and resistance to permanent kinking
The low resistance to permanent kinking and insufficient tear propagation strength of many conventional diffusers can lead to premature cracking under dynamic loads. The performance of the aeration system is significantly reduced as a result.
Pre-PUR® membrane tube diffusers are characterised by a very high tear propagation strength and far superior resistance to permanent kinking. The operational reliability and hence the performance of the aeration system are greatly enhanced.

|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 / deni-trification). 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.
