Actual operating experience on and design modifications to a zero discharge process-cooling tower wherein the waste waters provided the make-up. Design philosophy of the modification effort and resulting impact on thermal performance recounted. Additionally, the paper provides recommended design concepts for future reuse cooling towers where biological or hydrocarbon fouling risks are anticipated.
