Innovation in Water: Singapore, June 2011 - July 2012

This is an R&D book which showcases a selection of projects covering Intelligent Watershed Management, Water Treatment, Wastewater Treatment, Water Quality and Security, Network Management and Membrane Technology. Some of these projects are conducted in-house while others are test-bedding projects held in our facilities for performance check.

The projects also range from laboratory-scale systems to demonstration plants.
