Zero effluent operation illustrative examples

Illustrative Examples Using the Zero Effluent Mode of Operation... 

Two illustrative examples are presented. The first deals with the scheduling of a small batch process operating in zero effluent mode and the second deals with the synthesis of a small batch operation.

The zero effluent synthesis formulation was applied to a second illustrative example. In the example the number of processing units and the size of the central storage vessel were not known. The resulting plant required only 3 processing units and no storage vessel. The resulting schedule produced 68% less effluent than the same operation without wastewater reuse.
