Evaluation Of An On-Line Device To Monitor Scale Formation In A Brackish Water Reverse Osmosis Membrane Process, Jennifer C. Roque Jan 2012

Evaluation Of An On-Line Device To Monitor Scale Formation In A Brackish Water Reverse Osmosis Membrane Process, Jennifer C. Roque

Electronic Theses and Dissertations

A modified two-element membrane pressure vessel assembly has been used to monitor process operational changes in a full-scale reverse osmosis (RO) water treatment plant (WTP). This study evaluated the effectiveness of the assembly as an on-line monitoring device intended to detect scale formation conditions when connected to an operating RO process train. This study was implemented to support the requirements of a larger University of Central Florida (UCF) research project ongoing at the city of Sarasota’s Public Works and Utilities (City) water treatment facilities located in Sarasota, Florida. During the time-frame of this study, the City was in the process …


A Comparison Of Aluminum And Iron-Based Coagulants For Treatment Of Surface Water In Sarasota County, Florida, David Yonge Jan 2012

A Comparison Of Aluminum And Iron-Based Coagulants For Treatment Of Surface Water In Sarasota County, Florida, David Yonge

Electronic Theses and Dissertations

In this research, five different coagulants were evaluated to determine their effectiveness at removing turbidity, color and dissolved organic carbon (DOC) from a surface water in Sarasota County, Florida. Bench-scale jar tests that simulated conventional coagulation, flocculation, and sedimentation processes were used. Iron-based coagulants (ferric chloride and ferric sulfate) and aluminum-based coagulants (aluminum sulfate, polyaluminum chloride (PACl) and aluminum chlorohydrate (ACH)) were used to treat a highly organic surface water supply (DOC ranging between 10 and 30 mg/L), known as the Cow Pen Slough, located within central Sarasota County, Florida. Isopleths depicting DOC and color removal efficiencies as a function …
