Dissolved Air Flotation (DAF)

Overview

K-Pack DAF systems inject microscopic air bubbles to attach to oil, grease and fine suspended solids, lifting them to the surface for skimming. PWF compact and PWL high-capacity series suit demanding industrial duty.

How It Works

Process flow and treatment mechanism in simple steps:

1. 1

   Wastewater is conditioned with coagulant and flocculant as required.

2. 2

   A recycle stream is pressurised and saturated with dissolved air.

3. 3

   Micro-bubbles attach to pollutants and rise to the water surface.

4. 4

   Automatic skimmers collect floated sludge; clarified water exits via weirs.

Applications

Industries and situations where this product is ideal:

• Food and beverage processing
• Textile and tanneries
• Pulp and paper mills
• Slaughter houses and meat processing

Technical Highlights

Sizes, flow capacities, material options and design notes:

• 90–95% reduction of free and emulsified oil
• PWF compact / PWL high-capacity designs
• Rectangular or circular tank configurations
• Automatic sludge skimming; SS or mild steel construction

Specifications are indicative. Final design is engineered to your effluent and site conditions.
