Dissolved Air Flotation (DAF) Trade Waste Guideline Reviewed 1/03/ INTRODUCTION Grease arrestors are the simplest devices for the removal of grease and oil (GO), and fine suspended solids (SS) from trade wastewater. Their simple operating principle using adequate. Description. Dissolved air flotation (DAF) is a proven and effective physical/chemical technology for treating a variety of industrial and municipal process and wastewater streams. DAF systems are commonly used for the removal of oils greases and suspended solids to meet a variety of treatment goals including: Product recovery and reuse. Dissolved air flotation clarifiers operate effectively over a wide range of hydraulic and solids loading. DAF Corporation's FC-Maximizer clarifiers can be used for treatment of reservoirs, potable water treatment, water reclamation, screening, sludge thickening and treatment of industrial and municipal wastewaters.

The KROFTA™ Air Dissolving Tube (ADT)has been in use on Dissolved Air Flotation (DAF) clarifiers since the s. Since that time, thousands of ADTs have been put into operation, producing dissolved air in a recycle stream on a wide variety of applications and types of equipment. Before Dr. Milos Krofta invented the ADT, Krofta had used large and cumbersome pressure vessels for production of the aerated water stream. Dissolved air flotation (DAF) is a water treatment process for removing oils, solids, and greases from a water supply. The process helps clarify wastewaters by eliminating different types of suspended matter. DAF dissolves air in pressurized water – then releases it at atmospheric pressure.
