We analyze how lithium is extracted and recovered, a key metal today and that will play an extremely important role in future processes.
Overview of the different technologies for the treatment of wastewater generated in the washing of spent lead-acid batteries and for the recycling of heavy metals dissolved in the effluent.
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 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.
