Evaporation ponds allow water to evaporate through solar radiation and wind, leaving a pond of concentrated residual waste for treatment.
Concentrated baths and waters from metal treatments prior to paint application, contain toxic agents which are to be minimized by an appropriate treatment.
Biogas can be an energy source for leachate treatment: there are several technologies that can be applied to MSW landfill leachates treatment, however the method of vacuum evaporation, combined with or without pre- or post- reverse osmosis, has proven to be nowadays the most efficient method to minimize leachate and obtain purified water suitable for discharge.
Vacuum evaporation is a proven method for radioactive wastewater treatment that provides both good decontamination and volume reduction results.
Vacuum evaporation for landfill leachates treatment faces the polluting and environmentally hazardous leachates generated at MSW landfills.
Most companies in the power generation sector, both conventional and renewable, need to produce large amounts of vapor, leading to extremely high water consumption. Wastewater treatment is a must in theses plants and water reuse can be a solution to avoid huge water consumption.
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.
