Zero liquid discharge can be achieved by means of vacuum evaporation in many cases. Waste recovery rate is close to 100%
There are different technologies to treat brines, but only Vacuum evaporators and crystallizers have proved to be succesful to treat them. 95% of clean water can be obtained after the process.
The industrial vacuum concentrator is a solution for the production of natural chemicals and active ingredients with highest efficiency and lower costs.
Overview at the best technologies to treat waste in CSP plants: wastewater treatment, air emissions treatment and pure water production.
