Reverse Osmosis; Addressing Freshwater Shortage With Sustainable Desalination, Jessica Savage
Reverse Osmosis; Addressing Freshwater Shortage With Sustainable Desalination, Jessica Savage
Sustainability Conference
Water security is an imperative part of high-functioning societies. Currently, large populations of the globe live in water-impoverished or water-stressed areas. With climate change and growing global populations, projections show more people being impacted by issues of water shortage.
One solution to water security is the implementation of desalination, specifically with reverse osmosis systems. This presentation walks through the history, capabilities, future work, and explanations on how reverse osmosis systems work. With continued research on improving desalination, communities in both developed and developing nations around the world can work towards total water security.
High-Performance Zero Liquid Discharge (Zld) Treatment Of High-Salinity Brines Using A Multiple-Effect Absorption Distillation Concept, Sunil Pinnu
Dissertations, Master's Theses and Master's Reports
State-of-the-art zero liquid discharge (ZLD) technologies are currently bound with either intensive use of high-grade electrical energy such as mechanical vacuum vapor compressors utilized in brine crystallizers or high capital cost with environmental concerns such as evaporation ponds. The present study aims to address these issues by an innovative desiccant-based ZLD system in which a multiple-effect distillation (MED) unit is uniquely embedded at the heart of an absorption-desorption system. Here, the MED and absorption systems are inherently coupled enabling both heat and mass transfer processes between a high-salinity water and a desiccant solution. The proposed technology employs an absorption-based thermally-driven …
A Solar‐Driven Membrane‐Based Water Desalination/Purification System, Abdellah Shafieian Dastjerdi
A Solar‐Driven Membrane‐Based Water Desalination/Purification System, Abdellah Shafieian Dastjerdi
Theses: Doctorates and Masters
Lack of fresh water has turned into one of the major challenges of the world in the present century. Desalination of brackish or seawater has been proven to be one of the best solutions to cope with this global challenge. Among all the desalination methods, Membrane Distillation (MD) is well known as a cost effective and profitable technology for treating saline water. However, higher energy consumption compared to other separation techniques has been reported as MD’s main drawback. That is why the application of solar energy to provide the thermal energy requirement of MD modules has been the focal point …
