Double effect concentration plant for waste water
Open cooling tower circuits require liquid purge to avoid scaling problems within the cooling tower and the equipment served with the re-cooled water.
These cooling water blowdowns are typically characterized by relatively low concentrations of neutral salts, incl. hardeners, with traces of typical cooling water additives.
GEA Messo PT owns well qualified technology to concentrate the cooling water blow down to dry residue and to recover water in process water quality. In order to minimize operation costs, the process design is determined by energy efficiency and operation stability.
Typical process steps are:
- Chemo-physical treatment of the blow down water.
- Pre-concentration by means of membrane technology, if applicable.
- Thermal concentration using mechanical vapour recompression systems.
- Crystallization and separation of solids.
