Leaders in leachate treatment with reverse osmosis

Our main area of activity is the leachate treatment of waste, where we are leaders in the Portuguese and Brazilian markets. We are the only manufacturer of treatment systems using the reverse osmosis process in Portugal.
Leachate is a highly contaminating effluent produced in landfills, resulting from waste decomposition and rain precipitation to which the deposited mass is exposed.
It is a very complex mixture with high concentrations of salts and other organic and inorganic substances. Due to the composition and the variation of flow rates, this type of effluent can't use conventional treatment systems.
