What are the key points for selecting membrane? “Trouble-Free” and “Long Life” What are the usual troubles in membrane plants? 1. Fouling is serious, TMP increase fast and chemical cleaning is not effective 2. Fiber breakage frequently happens and treated water quality becomes bad 3. Treated water quality becomes bad without fiber breakage (long term performance durability)

1. Fouling is serious, TMP increase fast and chemical cleaning is not effective

Sharp pore size distribution & high porosity Less fouling

1. Fouling is serious, TMP increase fast and chemical cleaning is not effective

Strong chemical resistance of membrane can apply strong chemical cleaning condition

MICROZA membrane’s chemical cleaning condition up to

5,000 ppm of Chlorine

4% of NaOH

10% of HCl, H2SO4, Citric Acid

1% H2O2

2. Fiber breakage frequently happens and treated water quality becomes bad

Look at the long-term operated reference plants

San Patricio Water Works, USA - 30MLD, 300 modules - Operation started at 2000 - At 2007, 12 fiber breakage reported

Bedok NEWater plant, Singapore - 73MLD, 1,224 modules - Operation started at 2008 - No fiber breakage reported until now

2. Fiber breakage frequently happens and treated water quality becomes bad

In case of fiber breakage happens, detection and repairing procedure should be simple and obvious Direct integrity test with high pressure air !

MICROZA use 2 bar.g air for integrity test

Simple identification of fiber breakage through transparent joint

3. Treated water quality becomes bad without fiber breakage

Symmetric structure provides long term life and performance durability
