Title: A MODEL FOR INDUSTRIAL WATER REUSE: A GEOGRAPHIC INFORMATON SYSTEMS (GIS) APPROACH TO INDUSTRIAL ECOLOGY


1
A MODEL FOR INDUSTRIAL WATER REUSE A GEOGRAPHIC
INFORMATON SYSTEMS (GIS) APPROACH TO INDUSTRIAL
ECOLOGY
M.S. Thesis by Carolyn Eve Nobel The University
of Texas at Austin 1998
  • Presented
  • by
  • Berna Yenice-Ay, Ph.D.
  • March 12, 2003
  • University of Southern California

2
Motivation
  • Rising water costs
  • Limited water supplies
  • Waste minimization
  • Pollution control issues

3
Goals
  • More efficient water use
  • Water reuse
  • Conservation

4

Terms
  • Reclamation The treatment or processing of
    wastewater to make it reuseable
  • Reuse Beneficial use of treated wastewater
  • Recycling Capturing and recirculating the
    effluent within one water use or process

5
Categories and Specific Examples of Water
Reuse
  • Agricultural irrigation Crop irrigation,
    commercial nurseries
  • Landscape irrigation Parks, school yards,
    freeway medians, golf courses, cemeteries,
    greenbelts, residential
  • Industrial reuse Cooling, boiler feed, process
    water, heavy construction
  • Groundwater recharge Groundwater replenishment,
    salt water intrusion, subsidence control
  • Recreational and environmental reuse Lakes and
    ponds, marsh enhancement, stream flow
    augmentation, fisheries, snowmaking
  • Nonpotable urban reuse Fire protecting, air
    conditioning, toilet flushing

6
A MODEL FOR INDUSTRIAL WATER REUSE
  • a material reuse model
  • identifies cost-optimal reuse scenarios
  • a linear programming model
  • Geographic Information Systems (GIS) map-based
    framework
  • (integrates database operations with
    computer-based mapping)

7
What is GIS?
  • GIS
  • An organized collection of computer hardware,
    software, geographic data, and personnel designed
    to efficiently capture, store, update,
    manipulate, analyze, and display all forms of
    geographically referenced information.

8
Model
  • Objectives Minimize cost and maximize fresh
    water conservation
  • Considers product purchase, treatment, and
    transportation costs
  • Decision variables Flow rates of water from
    sources to destinations
  • Results are displayed on a map of the region
    along with accompanying data tables

9
Case Study
  • Bayport Industrial Complex in Pasadena, Texas
  • Contains an industrial wastewater treatment
    plant, a municipal wastewater treatment plant,
    and over 20 manufacturing facilities

10
Results
  • The optimal network reduces the fresh water
    consumption by 82. The cost savings is 19.
  • The water reuse model can be used for analyzing
    the use and reuse of other materials
  • Provides a quantitative tool to promote more
    efficient and sustainable system-based material
    cycles
