Hitachi develops cost-reducing adsorption filter

Hitachi Metals has developed a ceramic adsorption filter (CAF) as a pre-treatment for seawater reverse osmosis (RO) systems.

A study by Hitachi Metals and Nanyang Environment & Water Research Institute (NEWRI) shows a reduction in fouling on the RO membranes when the CAF is used as a pre-treatment. The amount of biofilm that attached on the RO membrane was significantly reduced. Overall, the finding is expected to reduce the cost of producing desalinated water.

Hitatchi is to accelerate commercialisation of the technology from its Singapore research base.
