Over the Years
The first research on a direct cooled EFC system was published in the US by Stepakoff.
1995 - 1999
Development at TU Delft
The first EFC crystallizers were developed at TU Delft. Indirect cooling was introduced and the first crystallizer was called the Cooled Disk Column Crystallizer (CDCC) followed by the Scraped Cooled Wall Crystallizer (SCWC).
2003 - 2004
Continuous EFC process
The continuous EFC process was developed at TU Delft for the recovery of Magnesium Sulfate for an industrial Magnesium Sulphate stream.
2005 - 2007
First unit was tested
The first skid-mounted EFC Pilot unit was tested successfully at Nedmag (Veendam, The Netherlands) on a waste Magnesium Sulfate stream followed by tests at AVR (Rotterdam, The Netherlands) on an industrial Sodium (Bi)Carbonate stream.
EFC Separations BV was founded
EFC Separations BV was founded as a spin-off company from TU Delft to develop and commercialise the EFC process.
