A system and process for recovering pure water and salts from wastewater using oil as a heat transfer medium and liquid salt collector. The wastewater is treated separately so that plant water and potable water result in separate brine streams that are subsequently combined prior to having the heated oil transferred thereto before entering an evaporator. The heated oil vaporizes the pure water in the evaporator and carries the salts from the evaporator as the salts are insoluble in the oil.
