Evaporation and Crystallisation
Generally, evaporation and crystallisation, are integrated
into a treatment process enabling optimal sizing and
operation, but their application in water treatment normally
involves either the recovery of water from a brine or waste
stream or the production of potable or process water from
groundwater or seawater.
Thermal processes, such as Evaporation and crystallisation
technologies in combination with other processes, such as
reverse osmosis (RO), are used to establish Zero Liquid
Effluent Discharge systems. The main purpose is to recycle
the effluent water as process water and to either recover
valuable components from the brine stream or to dump the
crystallised filter cake in the landfill. This not only prevents
contamination of the environment and cuts dumping fees
and penalties, but also provides a potential source of
income to the client.
