PROCESS AND SYSTEM FOR WELL WATER TREATMENT

摘要

There is provided a process for treating well water to produce drinking water. The process combines a vacuum tank process, an adsorption-desorption process, a heat-exchanger process, a membrane distillation-crystallization process. The process allows for some level of efficiency with regard to energy consumption and operational and maintenance costs.

主权项

1. A process for treating well water, comprising:
(a) submitting well water to a vacuum tank process to obtain water vapor and brine; (b) submitting the water vapor to adsorption and desorption processes in an adsorption-desorption unit having one or more columns; (c) submitting the water vapor from step (b) to a heat-exchange process to obtain the drinking water and brine, wherein heat is exchanged between the water vapor and brine obtained from step (a); and (d) submitting brine obtained from steps (a) and (c) to a membrane distillation-crystallization process to obtain drinking water and a solid waste, the drinking water being combined to the drinking water obtained at step (c).
