DAFs & CLARIFIERS

Reliable Separation for High-Quality Treatment

Dissolved Air Flotation (DAF) & Clarifiers

Advanced Solid-Liquid Separation

At Qtech Australia, we deliver precision-engineered solid-liquid separation systems that form the backbone of effective water and wastewater treatment.

Our Dissolved Air Flotation (DAF) units and Clarifiers are designed to remove suspended solids, fats, oils, grease (FOG), and other contaminants—ensuring your system stays compliant, reliable, and efficient.

Dissolved Air Flotation (DAF) Systems

High-Efficiency Surface Clarification

Our DAF systems are built to achieve rapid and reliable clarification, removing low-density particles that conventional sedimentation systems can’t handle. Using fine microbubbles, contaminants are floated to the surface and skimmed away, leaving behind clean, clarified water.

KEY FEATURES:
  • Automated Control – Integrated with SCADA/PLC for real-time adjustment, flow tracking, and load balancing
  • High Removal Rates – Up to 95% removal of suspended solids, FOG, and BOD/COD
  • Corrosion-Resistant Construction – Designed for long life in harsh environments
  • Compact Footprint – Ideal for retrofits or space-constrained sites
  • Custom Flow Capacities – From 1 kL/day to 500 kL/day
APPLICATIONS INCLUDE:
  • Industrial Wastewater
  • Food & Beverage Trade Waste
  • Slaughterhouse and Rendering Effluent
  • Mining & Resource Processing
  • Pre-treatment for Membrane Systems (RO/UF)

Lamella & Circular Clarifiers

Gravity-Powered, Engineered for Stability

Qtech Clarifiers provide a robust and passive solution for removing settleable solids through gravity separation. Whether lamella-type (inclined plate) for compact installations or circular clarifiers for high-volume applications, our systems offer low-maintenance reliability with engineered performance.

KEY FEATURES:
  • Modular Design – Scalable to your site’s flow and loading requirements
  • Optimised Settling Geometry – Engineered flow control for improved solids settling
  • Integrated Sludge Handling – Sludge cones and scrapers designed for minimal maintenance
  • Low Energy Consumption – Ideal for long-term, continuous operation
  • Compatible with DAF & Filtration Units – Seamless integration into treatment trains
APPLICATIONS INCLUDE:
  • Primary Sedimentation in WWTPs
  • Clarification after Coagulation/Flocculation
  • Pre-RO or UF Feedwater Polishing
  • Stormwater & Runoff Sediment Control
  • Lagoon Overflow Management
