Not Just for Milk Anymore, Pasteurization of Reclaimed Water in Ventura CA

摘要

Pasteurization has been widely used since the 1860s. Traditionally, this treatment process has been used to disinfect beer, wine, and milk, but not water. This simple, cost-effective process has now been independently validated for the water reuse market by Carollo and approved by the California Department of Public Health. The economy of pasteurization is based upon the capture of a waste heat source (e.g., turbine exhaust, solar heat, or cooling towers) and the transfer of that heat to the water for disinfection. Depending upon the production of digester gas, a wastewater utility can disinfect greater than 25 percent of their flow without any energy cost.
