OPS - Model DAF -Dissolved Air Flotation System
The OPS Dissolved Air Flotation (DAF) system is designed to clarify wastewater by effectively removing suspended solids, enabling both product recovery and water treatment that aligns with environmental regulations. With over a decade of experience, OPS has specialized in designing, manufacturing, and installing DAF systems across various industry sectors. Both stationary and mobile units are equipped with features to minimize operating costs and maintenance overhead. The DAF system demonstrates enhanced performance when integrated with an electrocoagulation unit, particularly in wastewater with high levels of fats, oils, or greases. Technically, the system supports a hydraulic loading rate of 1-2m3/hr per m2 of hydraulic separation area and a solids loading rate measured in kg/hr per m2. Known for engineering cost-effective solutions, OPS combines off-the-shelf products with high-throughput proprietary processes for tailored, site-specific efficiencies. This dedication ensures reliable performance and optimized lifecycle costs.

OPS DAF System Highlights
OPS have over 10 years’ experience in the design, manufacture and installation of DAF plants across a wide range of industry sectors. Both fixed and mobile OPS DAF units incorporate a range of key features that reduce operating costs and the maintenance overhead including:
- Air is infused into the recirculation pump therefore compressed air is not required.
- Variety of different recirculation pumps selected depending on the process.
- High efficiency lamella plates and/or coalescer packing to ensure maximum removal.
- High capacity sludge capacity.
- OPS units are designed to handle shock loads of solids (as this can be a common occurrence in wash plants).
- Remote telemetry can be added to enable remote surveillance.
- Dormancy – the DAF can go into a dormancy mode when there is no flow.
- Saturation vessel/pipe space efficiently built underneath the unit.
- Vented relief to prevent oversized bubbles• Variable height weir to alter flow capacity.
- OPS DAF can be a bespoke design to suit your location and waste water.
Where wastewater is contaminated with higher levels of fats, oils or greases, the DAF unit is combined with our electrocoagulation unit, significantly improving performance.
DAF units are sized on two factors namely:
- Hydraulic loading (this is the maximum flow rate that can be put through the unit whilst still giving sufficient time for the solids to rise to the surface, typically 1-2m3/hr of effluent per m2 hydraulic separation area).
- Solids loading rate (this is defined in kg/hr of solids per m2 of area
