DAF INTRODUCTION

Dissolved air flotation (DAF) is a water treatment
process that removes air by dissolving it in water
or wastewater under pressure and then releasing
it at atmospheric pressure in a flotation tank. The
released air forms tiny bubbles that adhere to the
suspended matter, causing the suspended matter
to float to the surface of the water, which can
then be removed by a skimming device.

FEATURES

1. Small footprint, about one-fifth of the volume
of the traditional dissolved gas system.
2. Low energy consumption, high efficiency, air
dissolution efficiency up to 90%.
3. Simple operation and management, stable
treatment effect and strong anti-blocking ability.

WORKING PRINCIPLE

Air flotation technology dissolves air into water
at a certain working pressure. During this
process, the pressurized water is saturated with
dissolved air and discharged into a flotation
vessel. The tiny bubbles generated by the released
air adhere to the suspended solids and float to
the surface to form a sludge layer. The spoon
removes thickened sludge. Finally, it completes
the purification of water.

APPLICATION

Dissolved air flotation is very widely used in treating the industrial wastewater
effluents from oil refineries, petrochemical and chemical plants, natural gas
processing plants, paper mills, general water treatment and similar industrial
facilities. Such as electroplating, food, slaughtering,brewing,tanning, printing, and
dyeing, paper making

Product Description

Product Description

Dissolved Air Flotation ( DAF System) is a water treatment process that clarifies wastewater (or other water, such as river or lake) by removing the susupended solids or oil & grease. It is widely used in the waste water treatment for solid-liquid separation, it can remove the suspended solids, oil & grease and colloidal substance effectively. Meanwhile, the COD, BOD can be reduced. It's the main equipment for the waste water treatment.

Structure Features

DAF System mainly consists of dissolved air pump, air compressor, dissolved air vessel, rectangle steel tank body, skimmer system.
1. Easy operation and simple management, convenient control the wastewater quantity and quality.
2.The micro bubbles produced by the dissolved air vessel are just 15-30um, it's adhesive with flocculant strongly to achieve better flotation effect.
3. Unique GFA dissolved air system,high efficiency of air dissolving can reach 90%+, strong ability for clogging
4. Chain-plate type skimmer, stable operation and high efficiency to scrap.

Working Theory

The dissolved air water produced by GFA system is pumped into the air releaser by reducing the pressure. 15-30um micro bubbles from the air releaser would adhere to the suspended solids make them lighter than water, then the solids combined with micro bubbles can float onto the surface to form a scum layer that would be scrapped by the skimmer system into the sludge tank. The lower clean water flows into the clean water tank. At least 30% of the clean water is recycled for GFA system while other is discharged or pumped to next process.

Application

DAF System, as one waste water treatment process, it is widely used in sewage purification engineering. It can be used for these industries:1. Paper industry -- pulp recycle in white water and clean water recycled for use.
2. Textile, printing and dyeing industry -- color chromaticity reduction and SS removal
3. Slaughterhouse and food industry
4. Petro-chemical industry -- oil-water separation
