Application
The project 'Combrine' concerns membrane distillation crystallization (MDC) with the aim of extracting valuable salts from seawater.
Aquastill has provided a small test installation with a capacity of approx. 1 ltr/hr.
The graph shows the boundary with elements that are probably economically feasible to extract from seawater.
