Desalination Concentrate Disposal: Salt Production For Zero-Discharge System
Since large-scale desalination started, the question of how to dispose
of the reject material produced by the process has occupied the minds
of engineers and economists. The quantity of brine discharged from
desalination plants is increasing, and this trend will be maintained
for the near future. The minerals extracted must have a value, but how
can this best be realised?
This summation of the current state-of-the-art in brine
disposal is an update of a paper originally presented at the European
Desalination Society's EuroMed conference in Jordan in November 2008.
The methods outlined provide both the production of a byproduct and
environmental protection by processing the outfall brine from
desalination plants.
The process is the first step towards the "zero discharge
system", and therefore the method should be considered as a novel
approach rather than a competitive one to the traditional thermal,
chemical and membrane processes.
