Evolution Of A Cooling Water Treatment Program At A Chemical Processing Plant, Lawrence P. Everson
Evolution Of A Cooling Water Treatment Program At A Chemical Processing Plant, Lawrence P. Everson
Retrospective Theses and Dissertations
During the construction of a chemical processing plant, a polyphosphate product was selected for use as a corrosion inhibitor in the open recirculating cooling tower system. After several months of operation, problems in the system made evident the fact that polyphosphate as a corrosion inhibitor was not acceptable. An organic corrosion inhibitor was substituted for the phosphate, resulting in improved corrosion protection and the elimination of phosphate fouling.

Electromagnetic Fields In Water Treatment, Robert H. Fagan
Electromagnetic Fields In Water Treatment, Robert H. Fagan
Retrospective Theses and Dissertations
Properties and characteristics of colloidal systems are reviewed with a discussion of colloid systems to be found in natural and wastewaters. Current electric and magnetic field theory are reviewed and summarized to provide practical application of the theory to engineering problems in the environmental field. Literature of colloidal reactions to electrical and magnetic fields is discussed and reviewed to ascertain areas of potential application of electric and magnetic phenomena to natural and wastewater treatment systems having objectionable colloid suspensions. It is concluded that application of electrical fields (electrophoresis) does not currently hold much promise for practical applications in water treatment …
Removal Of Color From Surface Water In Central Florida, Joseph R. Wanielista
Removal Of Color From Surface Water In Central Florida, Joseph R. Wanielista
Retrospective Theses and Dissertations
The USPHS limits color in water to 15 color units. However, it is desirable to remove all the color. Color in surface water is mainly due to humic substances and was found in concentrations varying up to 450 color units. Removal of color by coagulation and flocculation has been practiced over the years. The mechanisms involved have not yet been fully understood. During the course of this investigation, a literature survey, studying the nature of color, mechanisms or color removal, and optimum color removal conditions, has been conducted. Samples have been obtained from surface waters in Central Florida; namely Big …
The State-Of-The-Art Of The Coagulation/ Flocculation Process, David William Bouck
The State-Of-The-Art Of The Coagulation/ Flocculation Process, David William Bouck
Retrospective Theses and Dissertations
This report has been prepared with the idea of briefly summarizing the most important principles underlying the coagulations/flocculation process as it applies to water and wastewater treatment. The production of potable water from a supply which has been contaminated by naturally-occurring or man-made pollutants has been an object of concern throughout history. Several broad aspects have been considered in the report, such as the history, the nature and physical chemistry of colloidal particles, the theories of and the factors affecting coagulation/flocculation, and control of the coagulation/flocculation process. It is advisable for those persons engaged in the dynamic environmental sciences to …
