Natural organic matter (NOM) is a major cause of colour and odour in water. NOMs in drinking water can form carcinogen when reacting with chlorine. 
While large NOMs can be removed by segmentation or by filtration, removing small to medium sized NOMs with reasonable cost and efficiency is still a challenging topic.
Pesticides in the water source is another concern. An efficient and cost-effective treatment process is expected in this field also.

Develop a new process to produce potable (drinking) water by combining membrane-filtration and photo-catalytic process.
