The Role of Surface and Colloid Chemistry in the SIROFLOC Process
Chapter
Abstract
SIROFLOC is a water or wastewater treatment process developed at the CSIRO Division of Chemicals and Polymers’ Laboratories in Melbourne. In common with all other treatment methods which seek to remove colour and turbidity from natural waters, the SIROFLOC process is an interfacial one dependent for its success upon what happens at the various interfaces present within the system. This is a review of the many laboratory and pilot plant studies which have been undertaken during the development of the SIROFLOC process with the intention of better defining the role of surface and colloid chemistry.
