Aeration Sytems
An important part of the digestion process, aeration systems are an effective solution to coarse particle recovery in wastewater.

Combining floatation and density separation
Aeration sytems enable coarse particle recovery in wastewater. Conventional separation methods can often mean course material (up to 6 mm) is lost. A flotation device and a density separator aeration systems combine froth flotation and gravity separation.
Fluidized water is introduced through a network of pipes in the unit. As the air bubble dispersion rises through the bed, the bubbles become attached to the hydrophobic particles increasing their buoyancy. Meaning the lighter particles rise to the top while the denser particles settle and are discharged at the bottom of the separator. Typically used in the beverage and distilling industries Raptor’s range of aeration systems are designed to meet the needs.
Key features

Case studies

Complete waste water treatment plant for food production facility
Raptor Engineering were comissioned to design, manufacture and install a complete aerobic treatment system for a food production facility in Kent. The system incorporated a reverse osmosis (RO) and disinfection unit capable of achieving potable-grade water from recycleable to processed at a rate of 200m3 per day. Our team working closely with the client to scope, design and install the system. Managing and overseeing the project from concept to completion.

Aerobic wastewater treatment system for poultry processing plant
Raptor completed the design and installation of a bespoke aerobic wastewater treatment plant for a Poultry processing plant in Doncaster, UK. The system comes with fully automated controls and is capable of processing up to 1,600m3 of effluent per day.

DAF system for leading pet food manufacturer on Lancashire, UK
Raptor were commissioned to design and install a Dissolved Air Floatation (DAF) system for a leading pet food manufacturer in Lancashire, UK. Our team first scoped the project and then designed, built and installed an upgrade to the existing system. The new system now better meets customer needs and has the capability of processing up to 300m3/day of effluent per day.
