english Dissolved Air Flotation (DAF) technology is widely applied in various wastewater treatment scenarios. Below are four key application areas where DAF proves particularly effective.
Industrial Wastewater Treatment
Widely applicable to various industrial wastewater treatments, especially suitable for wastewater containing:
- Large amounts of fine suspended particles
- Grease and colloidal substances
- Animal and vegetable oils from food processing
- Protein impurities from slaughtering/breeding industries
- Fine suspended particles from chemical industries
- Organic colloids from pharmaceutical industries
DAF can efficiently separate these difficult-to-settle pollutants, reducing the load on subsequent treatment processes and ensuring effluent meets standards.
Municipal Wastewater Treatment
Suitable for pretreatment and advanced treatment stages of municipal wastewater containing:
- Small amounts of grease and fiber
- Suspended impurities
- Various organic pollutants
- COD content requiring reduction
In pretreatment, DAF prevents clogging of subsequent biological treatment systems and improves biological reaction efficiency. In advanced treatment, it facilitates wastewater reuse or discharge standards compliance.
Dyeing & Textile Wastewater
Meeting the treatment needs of wastewater containing:
- Large amounts of dyes and pigments
- Fiber debris and surfactants
- Highly stable colloidal systems
- Color compounds requiring removal
DAF efficiently separates colloidal and suspended impurities through bubble adsorption, helps remove color, and creates favorable conditions for subsequent decolorization and biochemical treatment.
Oily Wastewater Treatment
The preferred process for treating oily wastewater from industries including:
- Oilfield extraction
- Machinery processing
- Catering and food service
- Any source of emulsified or dispersed oils
DAF utilizes bubble adsorption and flotation characteristics to quickly separate oily substances from water, significantly reducing oil content and preventing environmental pollution.
