This study introduces a graphical method for reducing freshwater and wastewater in batch operations by reusing water within processes. The technique considers time and concentration constraints, essential for batch process targeting.

Area of Science:

  • Environmental Engineering
  • Chemical Engineering

Background:

  • Batch operations present unique challenges for water and wastewater minimization due to limited reuse opportunities.
  • Traditional methods often overlook the specific constraints of batch processes, impacting water management efficiency.

Purpose of the Study:

  • To present a novel graphical technique for freshwater and wastewater minimization in completely batch operations.
  • To explore the exploitation of inter- and intra-process water reuse and recycle opportunities within batch systems.

Main Methods:

  • Development of a graphical technique considering the two-dimensional constraints (time and concentration) of batch processes.
  • Application of first and cyclic-state targeting, crucial for batch operations.
  • Demonstration of water minimization using inherent storage in batch processes via a case study.

Main Results:

  • The graphical technique effectively identifies water reuse and recycle opportunities in batch operations.
  • Reversing the priority of time and concentration constraints impacts the final design.
  • The study highlights the necessity of first and cyclic-state targeting for batch processes.

Conclusions:

  • The presented graphical method offers a viable approach for water and wastewater minimization in batch operations.
  • Understanding and utilizing batch process storage is key to achieving water savings.
  • The methodology is currently limited to single contaminant systems.
