7.1.1 Air Scouring Patterns in Membrane Tanks

Membrane air scouring check is an essential routine maintenance procedure for newterra MBR
WWTP to ensure membranes are receiving effective physical cleaning. Air scouring has to be
observed for uniformity of bubbling action all across the membrane module/cassette on regular
basis.
A visual inspection of the aeration patterns should be performed with the liquid level 2-
3" (5 – 7.5 cm) above the top row of membranes and looking thru the tank viewport or
inspection opening (see below).
