DAF (Dissolved Air Flotation) Systems
High-Efficiency Dissolved Air Flotation (DAF) System
Maximize wastewater clarification with the Hydronovus DAF System. Delivering >95% TSS and >85% COD reduction through advanced micro-bubble technology.
High-Efficiency Dissolved Air Flotation (DAF) System
Short Description
The Hydronovus Dissolved Air Flotation (DAF) System is a proven and highly effective physical-chemical technology designed for advanced solid-liquid separation in industrial and municipal wastewater treatment. By introducing pressurized water saturated with dissolved air into the flotation tank, the system generates millions of microscopic bubbles. These micro-bubbles attach to suspended solids, oils, and greases, rapidly floating them to the surface where a mechanical skimmer continuously removes the concentrated sludge bed.
🌟 Key Engineering Advantages
- Exceptional Treatment Performance: Engineered to deliver outstanding purification, achieving a Total Suspended Solids (TSS) reduction of $>95\%$ and a Chemical Oxygen Demand (COD) reduction of $>85\%$.
- Advanced Micro-Bubble Technology: The integrated dissolved air system ensures a highly stable air-liquid mixture, generating uniform micro-bubbles that provide a massive surface area for optimal floc attachment.
- Robust & Versatile Operation: Designed to handle severe industrial effluents, including wastewater with high salinity levels.
- Energy-Efficient Design: Optimized hydraulic flow and highly efficient main motors keep operational energy consumption low, significantly reducing long-term plant overhead.
- Compact Integration: The system integrates the separation tank, dissolved air system, and automated skimmer into a single, space-saving footprint, allowing for straightforward installation.
