20–30 m³/h DAF System Industrial Wastewater Treatment Unit
The 20–30 m³/h DAF system is a dissolved air flotation wastewater treatment unit designed for efficient solid-liquid separation. It removes suspended solids, oils, and colloidal particles by generating fine microbubbles that attach to contaminants and float them for removal. The system is suitable for continuous industrial and municipal wastewater treatment applications requiring stable clarification performance. It provides reliable operation for medium-capacity plants needing effective pretreatment and water quality improvement under varying influent conditions.

Product introduction of 20–30 m³/h DAF System
The 20–30 m³/h dissolved air flotation system is a compact wastewater treatment unit engineered for efficient separation of suspended solids, grease, and floating impurities. It is constructed with durable materials and designed for continuous operation in industrial environments. The system integrates air dissolution, flotation separation, and sludge removal in a single process. It is widely used in facilities requiring stable wastewater pretreatment or discharge compliance, including food processing, textile production, petrochemical plants, and municipal sewage systems where reliable clarification and pollutant removal are essential.
Working Principle
The system operates by dissolving air into water under pressure to form a supersaturated solution. When released into the flotation tank, microbubbles are generated and attach to suspended solids, oils, and colloids. These particles rise to the surface as sludge foam and are removed by a scraping system. Heavier solids are separated and collected in a sludge tank, while clarified water exits the system for further treatment or discharge.
