Cascade Models for Targeting and Synthesis of Total Water Networks

Cascade Models for Targeting and Synthesis of Total Water Networks

Success in the race for efficiency means for today’s process industries their survival. The most critical resources are energy and water, with the latter being a crisis factor when in shortage. Effective water savings are achieved by reuse, regeneration and recycling. The selection of regeneration t...
