It is of great significance to introduce regeneration/treatment units into a water system. Regeneration units and treatment units are the same in function and application, but different in destination of the outlet streams. The outlet streams of the regeneration units will be reused/recycled in the water system. The outlet streams of the treatment units will be discharged to environment. This paper provides a review of the development in designing and targeting of continuous water systems involving regeneration/treatment units. The features of Pinch Analysis methods and mathematical programming methods are discussed for the integration of regeneration system, treatment system and total water system separately. For a water system involving regeneration unit, it is addressed that the system can be formed by adding one or more additional source(s), regenerated stream(s), into a water system involving reuse only. The contribution of Liu's group based on the above insight is outlined. Finally, this review offers a guide for future efforts in the integration of water systems involving regeneration/treatment.
