FAQ
- How does DAF remove oil from wastewater? DAF dissolves air into water under pressure, then releases it as micro-bubbles that attach to oil droplets and suspended solids, floating them to the surface where a skimmer removes them.
- What is the typical suspended solids removal rate of a DAF unit? Typical removal rates are 85–95% for suspended solids and 90–98% for oil and grease, depending on wastewater characteristics and chemical dosing.
- Does DAF require chemical dosing? Most DAF applications benefit from coagulant/flocculant dosing to improve removal efficiency. The skid includes a dosing interface for this purpose.
- What power supply does the DAF skid need? Standard power supply is 380V / 50Hz. Other voltages are available on request.
- Is the DAF skid suitable for food processing wastewater? Yes, DAF is widely used in food processing for grease and suspended-solids removal before discharge or biological treatment.
- How is the DAF skid shipped? The skid is modular and sized for standard container shipment. It arrives pre-assembled and factory-tested.
