From page 67...
... The three major imported resources are energy, water, and chemical entities, and the undesirable outputs are airborne contaminants, wastewater, and sludge. Therefore, from an industrial perspective sustainable growth goals include reducing both resource consumption (e.g., water)

From page 68...
... Typically, there is also raw water treatment, especially when surface water is being used; wastewater treatment, which includes removing solids; and biological treatment. Integrated water management entails evaluating and optimizing all of the resources used for an entire site.

From page 69...
... Figure 9.8 shows a five-step approach developed by Ondeo Nalco for site-wide integration of the water resources. The first step is scope development, which involves clearly defined goals and a detailed project plan, including a time line and the resources required.

... WATER RESOURCE MANAGEMENT EXAMPLES Virtual Paper Mill In this simulation of an integrated mill, a very small part of the pulp and paper process involving only the paper machine is examined (Figure 9.10~. It is a very fairly complex stream or flow sheet that helps to optimize water use in the mill.

... The green biocides have also shown improved control of microbes. Automation and Cooling Water The Erin Brockovich, Pacific Gas & Electric, story helped bring to light the issue of chromate use in industry cooling towers.

From page 72...
... Chromate has been found to be very harmful to humans exposed to air emissions from cooling towers. The blowdown from the cooling tower is supposed to be a zero liquid discharge, but the rubber linings can give out and this is what led to the aquifer contamination that Erin Brockovich identified.

... There is tremendous growth to be made here, and it will play a very critical role going forward in industrial water management. DISCUSSION Microbial Monitoring Dick Carlson, of San Diego County, was looking at the use of recycled water for cooling towers.

From page 74...
... integrated Source Approach for New Facilities Dan Askenalzer, of Montgomery, Watson, and Harza, was curious about whether industrial clients building new facilities are requesting that an integrated resource approach be incorporated up front in the design of this new facility.
