This powerpoint presentation outlines two water reuse case studies. The fist case study presents water reuse opportunities within an existing bio-pharmaceutical manufacturing facility in North Carolina, which includes a modeling and economic evaluation of
water reuse in cooling towers. The project objective was to identify and evaluate water reuse opportunities
that have a greater than 5% reduction in city water
consumption at the facility. Experimental approach methods included: site water balance review;
identifying options for reuse;
evaluating technical feasibility; and,
evaluating economic feasibility. The second case study presents a pharmaceutical tablet manufacturing facility in
Ireland, which includes
API removal from wastewater and effluent reuse. Project objectives and scope included:
designing a new treatment plant
specifically for API removal from
pharmaceutical manufacturing plant
wastewater and effluent reuse; and, developing
criteria for effluent reuse in cooling
towers - no APIs, low COD, low TDS,
and low/no coliforms. APIs of concern are listed, along with wastewater characteristics and license limits; process flow diagram; the Ireland Manufacturing Plant; and, Pharma WWTP effluent results with respect
to suitability for reuse in cooling towers. Conclusions indicate that: the combination of MBR+Ozone results in
complete API removal and a high quality reusable
effluent in cooling towers;
need to blend effluent with city water to
increase COCs above 3;
ozone effectively destroys APIs to non-detectable
levels, albeit at high dosages (>60 ppm); requires adjustments to water chemistry; and,
operate cooling tower at 3 cycles or lower or have
softener backwash and RO reject bypass WWTP. Includes tables, figures.
