The Dissolved Air Flotation (DAF) system is imported from the Netherlands and is used for pre-treatment to improve water quality before it enters the potable water production system or wastewater treatment system. This system is ideal for raw water containing floating solids such as algae, fats, and oils, which conventional sedimentation systems cannot handle.​

The DAF system is designed for high efficiency, occupying less space and being mobile (Mobile Unit). The patented i-AERATION system generates fine air bubbles, which help float contaminants to the surface of the water, making the removal of pollutants easier.​
