High efficiency cavitation air flotation for laundry water recycling

CAF cavitation air flotation is an advanced wastewater treatment equipment that clarifies wastewater by removing suspended matters such as oil or solids.

Because of its excellent and stable performance, cavitation air flotation is now widely used industrial wastewater treatment and municipal sewage water purification as pretreatment process to remove oil, grease, fats, colloids and other suspended solids.

By dosing suitable flocculants and coagulants into wastewater, grease removal rate can be more than 95%, suspended solid removal rate can be more than 90%, COD and BOD removal rate can be around 60%.

As an experienced manufacturer started in year 2006, we provide one-stop services from project design to manufacturing, installation and final commissioning, professional services with cheap factory price for you.

Working principles of CAF laundry water recycling cavitation air flotation :

The feed water to cavitation air flotation machine is often (but not always) dosed with a coagulant (such as ferric chloride or aluminum sulfate) to coagulate the colloidal particles and/or flocculants to conglomerate the particles into bigger clusters.

Wastewater firstly access into an aeration section, CAF aerator is placed here.  With high speed rotating of impeller, a vacuum zone is formed under water. Air above water level is absorbed into water and generate micro-bubbles.

These bubbles attach to, and form within, the solids or chemical flocculants entering the vessel, causing them to float to the surface where they are retained and subsequently removed by a skimmer.

Product features of CAF laundry water recycling cavitation air flotation :
CAF cavitation air flotation is an economical and reliable wastewater treatment equipment, mainly used as pretreatment process to remove suspended solids.

1. High adaptability
It is a physical separating process, suitable for different water quantity and water quality at different working peroid.

2. Save investment
Compare to DAF system, cavitation air flotation machine don't need any of pressure vessel, air compressor, circulating pump or jet, greatly reducing investment.

3. Affordable
Cavitation air flotation machine is simple in structure, only a few ancillary civil work is required, can be installed above ground, underground or at high altitude position.

4. Low operating costs
Low power requirement, easy to operate and maintain, saving labor.

5. High efficiency
Sludge will be removed automatically and continuously from wastewater, low sludge moisture content greatly reduce the subsequent sludge disposal costs.

6. Reduce odor
It is an aerobic process, sludge odor problem is effectively resolved.

CAF cavitation air flotation is widely used in wastewater purification to remove oil, grease, fats and other suspended solids to meet a variety of treatment goals including:

• Product recovery and reuse
• Pretreatment to meet sewer discharge limits
• Pretreatment to reduce loading on downstream biological treatment systems
• Polishing of biological treatment effluent
• Thickening of biosolids
