GENERAL DESCRIPTION---CAVITATION AIR FLOTATION PLANT (CAF)

Our CAF flotation equipment removes suspended solids, oils, fats and colloids from wastewater. They have a compact and functional design and are easy to install, operate and maintain.

The cavitation air flotation system injects microbubbles into the wastewater directly inside of the equipment, without the need for prior dissolution of the air in the wastewater stream. These microbubbles, once introduced into the aqueous medium, allow the flotation of buoyant particles and the sedimentation of solids in the same equipment.

 

FUNCTIONING OF CAF SYSTEM

Air is sucked in from the outside by specially designed aeration equipment and is introduced pressurized into the CAF chamber where, in contact with the wastewater, air microbubbles are generated. Suspended solidsadhere to these microbubbles and are floated to the surface where a system of skimmers sweeps solids, oils and greases from the surface of the water.

The solids that have settled due to their greater weight, are collected at the bottom of the equipment.Both floated and settled sludge are directed to a sludge container.Part of the clarified water is recirculated back into the equipment; this allows to avoid the formation of sediments on the equipment surfaces

 

MAIN COMPONENTS

Flotation chamber
The interior of the CAF equipment houses a volume of wastewater into which the air is injected using blowers. Microbubbles are generated in this chamber and the effect of adhesion and flotation of solids takes place.

 

Floated solids skimmer
It is a system of metal plates driven by a simple and automatic chain mechanism. It carries away the sludge composed of floated solids, oils, fats, etc. removing them from the surface of the clarified water.

 

Aeration system
The aeration system of our CAFsis simple and robust, made up of aair suction pump and an injector withblower that introduces the sucked air insidefrom the CAF team chamber.

CAF APPLICATIONS

CAF clarification can be applied in many different processes: in pre-treatment as primary clarification generally preceded by a physical-chemical coagulation-flocculation process; as secondary clarification after a biological treatment; It is also applied in tertiary treatments.

CAF technology is a high effective process for  all types of industries:

• Food processing
• Slaughterhouses
• Meat processing and canning
• Chemical and pharmaceutical
• Dairy
• Sweet drinks and juices
• Cosmetic
• Paper
• Tannery
• Leachate treatment
• Oil and gas
• Fragrances, perfumes and essential oils
• Biodiesel and biomethane
• Municipal and industrial wastewater treatment plants
