Abstract:
1. A system to provide waste water purification services, the system comprising: at least one separation unit, each separation unit comprising a mechanical vapor recompression separator, a primary heat exchanger, a steam stripper, and a secondary recovery heat exchanger; wherein the mechanical vapor recompression separator receives a recirculation stream comprising a combination of a waste water stream and a recycled liquid bottoms stream, the recycled liquid bottoms stream being supplied from the mechanical vapor recompression separator; wherein the primary heat exchanger receives an evaporation stream from the mechanical vapor recompression separator and the recirculation stream, the primary heat exchanger facilitating heat transfer between the evaporation stream and the recirculation stream; wherein the system for wastewater purification receives water from a waste water storage, purifies the water, and returns the purified water to a purified water storage.
