Evaluation Of An On-Line Device To Monitor Scale Formation In A Brackish Water Reverse Osmosis Membrane Process, Jennifer C. Roque
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 …
Evaluating Corrosion Control Alternatives For A Reverse Osmosis, Nanofiltration And Anion-Exchange Blended Water Supply, Rebecca J. Wilder
Evaluating Corrosion Control Alternatives For A Reverse Osmosis, Nanofiltration And Anion-Exchange Blended Water Supply, Rebecca J. Wilder
Electronic Theses and Dissertations
The research reported herein describes the study activities performed by University of Central Florida (UCF) on behalf of the Town of Jupiter Water Utilities (Town). The Town recently changed its water treatment operations from a combination of reverse osmosis (RO), lime softening (LS) and anion-exchange (IX) to a combination of RO, IX and nanofiltration (NF). Although this treatment change provided enhanced water to the surrounding community in terms of better contaminant removal and reduced DBP formation potential, integration of the NF process altered finished water quality parameters including pH, alkalinity and hardness. There was concern that these changes could result …
Application And Optimization Of Membrane Processes Treating Brackish And Surficial Groundwater For Potable Water Production, Jayapregasham Tharamapalan
Application And Optimization Of Membrane Processes Treating Brackish And Surficial Groundwater For Potable Water Production, Jayapregasham Tharamapalan
Electronic Theses and Dissertations
The research presented in this dissertation provides the results of a comprehensive assessment of the water treatment requirements for the City of Sarasota. The City’s drinking water supply originates from two sources: (1) brackish groundwater from the Downtown well field, and (2) Floridan surficial groundwater from the City’s Verna well field. At the time the study was initiated, the City treated the brackish water supply using a reverse osmosis process that relied on sulfuric acid for pH adjustment as a pretreatment method. The Verna supply was aerated at the well field before transfer to the City’s water treatment facility, either …
