Microza without DAF has been operating Since 2013.
It’s efficient even in Algae bloom event by adjusting cleaning regime.

Summary
Microza employing TIPS PVDF membrane has
significantly robust and chemical resistant.
This features enable it to operate effectively in sea
water desalination without conventional pre-
pretreatment such as DAF, DMF even during red tide
and algae bloom event.
Microza has been proven most effective and longest
lifetime in sewage effluent recycling plants in
Singapore.
