(54) Title: AERATION DIFFUSER FOR PRESSURIZED LIQUID TREATMENT MODULE AND METHOD OF OPERATING SAME o CJ Fig. 3 (57) Abstract: An aeration diffuser (12) for a pressurized liquid treatment module includes a base having a gas passageway (32) and a liquid passageway (50) fluidically separated from the gas passageway. Liquid is injectable into the li­ quid passageway of the base of the diffuser. Li­ quid flows through the base of the diffuser and into the module to be filtered by filtration mem­ brane (s) within the module. Gas is injectable into the gas passageway of the base of the diffuser. Gas flows through the base of the diffuser separ­ ately from the liquid to aerate the filtration mem­ brane (s) within the module. Further a module in­ cluding one or more diffusers and a method of fil­ tration is discloseed. LIQUID wo 2014/011204 AI III llll IIII III III III llll III III Hill lllll llll 111 III!
