Dissolved Air Flotation (DAF) System

Dissolved Air Flotation (DAF) System

Overview

The Dissolved Air Flotation (DAF) System offered by Renora Hydrotech Pvt Ltd is a highly efficient solid-liquid separation technology used in wastewater treatment processes. The system effectively removes suspended solids, oils, grease, and other contaminants by injecting air into water under pressure. This process creates microbubbles that attach to impurities, allowing them to float to the surface where they can be easily removed.

DAF systems are widely used in industrial and municipal wastewater treatment plants to improve water quality and enhance downstream treatment efficiency.

Working Principle

In a DAF system, air is dissolved in water under pressure and then released at atmospheric pressure inside a flotation tank. The released air forms extremely fine bubbles that attach to suspended particles in the wastewater.

These bubbles lift the particles to the surface, forming a floating sludge layer. A mechanical skimmer then removes this sludge, while the clarified water flows out for further treatment or discharge.

Key Features

  • High removal efficiency for suspended solids, BOD, COD, oil, and grease
  • Compact design with a minimal installation footprint
  • Available in skid-mounted or containerized models
  • Optional chemical dosing systems for improved treatment performance
  • Easy installation and low maintenance
  • PLC-controlled automation for reliable and efficient operation
  • Durable construction designed for long operational life
