Dissolved Air Flotation

Enpure engineers and delivers effective water supply solutions utilising both conventional and emerging technologies. We are continually developing our expertise and technologies to be able to meet the latest quality standards.

Dissolved Air Flotation

Dissolved Air FlotationWe have been at the forefront in being able to offer technologies that operate at high rate, reducing footprint and land requirements. Enpure introduced Dissolved Air Flotation (DAF) into the UK in 1972. 

More recently we introduced Enflo-ViteTM which is part of the Enflo-DAFTM family.  This is another major breakthrough in process intensification which can be retrofitted to provide increased capacity from existing assets.  In contrast the Enpure Enflo-FiltTM was the forerunner of systems that combine flotation and filtration in a single process unit providing opportunities for further savings in plant footprint.  The Enflo-PITM modular system provides effective distribution of saturated water to our latest patented DAF nozzles whilst being straight forward to install within DAF tanks up to 16m wide.
