The Philadelphia Water Department, through its water quality and research division and its operations divisions, conducts studies to develop better methods of control of chemical doses, and greater efficiency in the use of chemicals. In previous laboratory, pilot plant, and full‐plant scale tests on coagulation, the laboratory jar stirring test has been used as a control method, and research has been directed to the effectiveness of various coagulants‐alum, ferrous and ferric salts, and sodium aluminate and of numerous coagulant aids. In this continuing work, the use of a zeta potential (ZP) microscope and cell was investigated. Some of the preliminary study results obtained with this equipment are presented, along with a brief discussion of the published findings of other writers and of the purpose and possible future use of ZP.
Recent research has advanced the technology of chemical coagulation and sensory quality control. A number of contributions have elucidated the role of the electrophoretic state in coagulation. With new instrumentation there is promise that electrophoretic techniques will find greater field application and assist the operator in improving water treatment efficiency. Other articles have described the effect of various parameters, including synergism and antagonism, in measurement of odor in water. The objective of this study was to demonstrate the applicability of these techniques in the field. Studies at the Torresdale Plant of the Philadelphia Water Department are described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
