Description
Dissolved air flotation (DAF) Unit Water Clarification
The DAF Unit is designed with a large surface, is especially suited to treat sewage with a large flotation sludge volume. Process water which is flocculants through flocculants system then directed to the DAF tank. The influent to be treated is blended with 'milky water', an emulsion of millions of micro bubbles are generated when the pressure of air saturated water is suddenly released. Up to 25^30% of the effluent is re-circulated for the generation of pressure water through a multi stage side-channel pump. A compressor feeds air to the pump rotor that generates micron bubbles with a large surface for water saturation. The water with air is completed in a reactor tube then flow into flotation cell through pressure release valve. Only the top of portion of this concentrated sludge is skimmed to sludge compartment. The sludge skimmer system is constructed of stainless steel chain and clamp type plate holding a flexible, semi-rigid rubber wiper. The sludge into the sludge tank by gravity enhanced de-watering.

DAF System Clarifier Cost-Effective
Our packaged DAF plants are pre-assembled and pre-tested in our controlled facility, often saving 50 percent or more over in-situ construction. They can also be integrated into pre-engineered building systems for increased savings and reduced schedule. Their small footprint also reduces building costs.
Simplicity
Our DAF plants are quiet, simple and easy-to-operate with minimal operator input. They are also supplied complete with chemical dosing, water quality instrumentation, automatic controls and monitoring systems customized to meet local needs.
