More than last 10 years ago, ELVAL installed the first European Zero Liquid Discharge (ZLD) plant for coil coating at its factory located in Inofita, Greece.
The operation of the ZLD plant enables ELVAL to process all of their waste streams from lamination to coil coating operations in a single wastewater treatment for coil coating plant.
The Zero Liquid discharge for aluminium coil coating designed and installed by CIE is able to treat and recycle 750 m3/day of their waste waters, allowing for a savings of greater than 98% of the total water consumption.
The Coil coating wastewater treatment plant installed by CIE is able to achieve 98% water recovery and recycle by reducing the aluminium and calcium salts prior to the evaporator, which is able to operate with both hot water or steam and can utilize waste heat from other operations, including cogeneration to further reduce energy consumption.
