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.
