Success stories
Installation for treatment of leachate from MSW plant
Customer: Hera Holding (Barcelona)
Year: 2020

Installation for the evaporation of wastewater from the rejection of a reverse osmosis treating leachate generated in a Waste Treatment Center, with a capacity of 4 Tm/h.

The installation is fundamentally composed of a multiple effect evaporator under vacuum regime, the first effect (multitubular) working with the hot water coming out of the electric cogeneration motor, the second effect is monotubular with falling film configuration and the last effect is monotubular of rising forced circulation. In addition, there is a finisher -a crystallization reactor- energetically combined with the main evaporation unit, as well as thermal recuperators. The whole Plant is automatically operated by a SCADA system.

By taking advantage of the residual hot water from the cogeneration engine for evaporation, the energy efficiency of the system is maximum, minimizing operating operating costs.
