Process Economics for Water Purification: A Comparative Assessment

  • David F. Ollis
Part of the NATO ASI Series book series (ASIC, volume 237)


A preliminary comparative examination is made between a known water purification technology (activated carbon adsorption), an emerging photoprocess technology (photolytic ozonation), and an hypothetical photocatalyzed process. The example feed stream is contaminated with particulates and a non-volatile halocarbon (PCB example). The process comparisons assume a common pretreatment section for all three processes. Conditions under which heterogeneous photocatalysis may be competitive are indicated.
