STARK Dissolved Air Flotation (DAF) System for Industrial Wastewater Pretreatment

High-Efficiency DAF System for Solid-Liquid Separation in Industrial Wastewater The STARK Dissolved Air Flotation (DAF) System is a reliable and efficient solution for removing suspended solids, oils, greases, and other contaminants from industrial wastewater. By injecting microbubbles into the water stream, the system lifts fine particles to the surface for easy skimming, ensuring optimal pretreatment before biological or membrane filtration processes. Widely used in food processing, petrochemical, textile, and slaughterhouse industries, the DAF system enhances overall water clarity and reduces the burden on downstream units. Compact, customizable, and fully automated, it delivers consistent performance with minimal maintenance.

Product Description

Working Principle and Design Highlights of STARK DAF System

The STARK Dissolved Air Flotation (DAF) System operates by dissolving air under pressure into wastewater and then releasing it at atmospheric pressure within a flotation tank. This process forms microbubbles that attach to suspended solids, oils, and greases, causing them to float to the surface where they are mechanically skimmed off.

The core components of the system include:

  • Pressurized Dissolution Tank: Ensures uniform air distribution for effective flotation.
  • Microbubble Release Valve: Precisely controls air release, enhancing particle capture.
  • Skimming Mechanism: Automatically removes floated sludge, reducing manual intervention.
  • Sludge Hopper: Collects and concentrates sludge for easy discharge or further processing.

 

In addition to the standard configuration, STARK DAF systems can be integrated with:

  • pH and coagulation dosing systems for enhanced floc formation,
  • automated backwash units for continuous operation,
  • customized control panels with real-time monitoring.

 

Designed with corrosion-resistant stainless steel and anti-clogging flow paths, the system supports long-term operation even in aggressive wastewater conditions. Its modular design also allows for rapid deployment and scalability.

Stark Advantage

Advantage One: Advanced Microbubble Technology for Maximum Removal Efficiency

The STARK DAF System utilizes ultra-fine microbubbles to significantly enhance the separation of suspended solids, oils, and grease from wastewater. This advanced flotation mechanism ensures high removal rates with minimal chemical consumption. Compared to conventional clarification systems, STARK’s microbubble technology offers:

  • Faster separation and shorter retention time
  • Better performance with lower flocculant dosage
  • Consistent effluent quality even under fluctuating loads

This makes it especially suitable for industries that require stable discharge performance under varying conditions.

Advantage Two: Modular Design with Low Operational Costs

STARK DAF units are built with a modular architecture, allowing for easy expansion, transport, and on-site installation. This design approach also simplifies integration with pretreatment or post-treatment units. Additional operational advantages include:

  • Low power consumption due to optimized air saturation system
  • Easy access for maintenance and sludge discharge
  • Customizable automation for chemical dosing and monitoring

These features significantly lower long-term costs and improve reliability, making it a cost-effective investment for both new and retrofit wastewater treatment projects.
