SYNOPSIS T he performance of the Clariflow process has been evaluated at the Sandown sewage‐treatment works of the Southern Water Authority, Isle of Wight, by the WRc Processes section. The process is designed for the partial treatment of sewage prior to discharge in estuarine or coastal locations. As a marine treatment it represents an alternative to the use of long sea‐outfalls. The Clariflow process effectively reduces total, faecal coliforms and salmonellae, and may reduce viruses. Screenings are totally removed and phosphorus and heavy metals are significantly reduced. Solids and BOD removal levels are superior to those achieved by conventional primary processes. The paper reviews the development of the process, the results of the evaluation and cost information. Recommendations have been made to further optimize performance.
