There are different alternatives for brine treatment, but Zero Liquid Discharge systems are the most respectful option for the environment.

We analyze the differences between two leachate treatment processes. One of them includes a wastewater evaporator that improves the performance of the process.
We analyze the results of using vacuum evaporators to treat leachate from a a landfill, displaying the environmental performance and the economic results.
Waste sent to MSW landfills is subjected to a compaction process that generates liquid drainage containing hazardous pollutants. This waste should be subjected to a purification treatment before being discharged into the general collector.
Biogas purification through backwashing with pressurized water is the most flexible technology available for the treatment of biogas, regardless of the quality and quantity of the stream.
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 for landfill leachates treatment faces the polluting and environmentally hazardous leachates generated at MSW landfills.
