Recovery Optimization for Brackish Groundwater Desalination
The objectives of this study were to optimize and increase the overall feed water recovery of the desalination process and thereby reduce concentrate volume....
Guidance Development for Energy Optimization and Renewable Energy for Desalination Plant
Energy is often the most significant factor in the affordability and sustainability of treating various different source waters by desalination. More than 33% of the cost to produce water using reverse osmosis technology is attributed to electrical demands. As a result, there is considerable interest in optimizing energy and employing renewable ene...
Reverse Osmosis Permeate Stabilization Using Micronized Calcium Carbonate: A potential Alternative to Lime
Paper addresses the inherent problem of Reverse Osmosis (RO) permeate corrositivity to concrete and metal because of its low pH and Langelier Saturation Index. Specific study results are offered relative to the use of micronized calcium carbonate instead of lime for RO permeate stabilization....
Energy Minimization Strategies and Renewable Energy Utilization in Seawater Desalination
Summary of renewable energy sources (wind, solar, biogas, geothermal) and energy reduction strategies for the minimization of greenhouse gasses (GHG). Technologies include distillation, microbial desalination cells, ion concentration polarization, and forward osmosis....
Minimization of Desalination Energy Consumption Using Emerging Technologies
Reducing energy consumption is critical for lowering the cost of desalination and addressing environmental concerns about greenhouse gas (GHG) emissions from the continued use of conventional fossil fuels as the primary energy source for seawater desalination plants.In this study, a comprehensive literature review was conducted to gather informatio...
Seawater Desalination Energy Minimization Using Nanocomposite and Semi Batch RO
Seawater desalination is a promising option for a steady supply of high-quality water from the abundantly avialable source of ocean water, but the process is energy intensive. In this paper, nanocomposite RO and semi batch RO were evaluated at the pilot scale for energy minimzation during seawate desalination. The objecties were to: 1) compare the ...
An Emerging Application for Low-Pressure Membranes: Treatment of Backwash Waste at Surface Water Treatment Plants for Potable Reuse
In this study, guidance is provided for applying microfiltration (MF) and ultrafiltration (UF) membranes to treat full-scale granular media filter (GMF) backwash water at drinking water plants. An example from the City of Melbourne in Florida is presented with the current approach to backwash water management at the full-scale along with a proposed...
