Treatments of reverse osmosis concentrate using natural zeolites

Energy and Resources Recovery from Reverse Osmosis Desalination Concentrate

The overarching goal of this research project is to develop technologies for beneficial salinity management. Specifically, the project focuses on the energy and resources recovery from reverse osmosis (RO) desalination concentration, which can reduce the cost associated with desalination operation and minimize the environmental impact associated with the disposal of desalination concentrate. Th...

A Novel Photovoltaic Powered Reverse Osmosis with Improved Productivity of Reverse Osmosis and Photovoltaic Panel

With the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. Domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. The novel concept of photovoltaic powered ...

Accelerated desupersaturation of reverse osmosis concentrate by chemically-enhanced seeded precipitation

Selective removal of arsenic and monovalent ions from brackish water reverse osmosis concentrate.

Concentrate disposal and management is a considerable challenge for the implementation of desalination technologies, especially for inland applications where concentrate disposal options are limited. This study has focused on selective removal of arsenic and monovalent ions from brackish groundwater reverse osmosis (RO) concentrate for beneficial use and safe environmental disposal using in sit...

Sorption of metals and metalloids from reverse osmosis concentrate on drinking water treatment solids

Drinking water treatment solids (DWTS) from coagulation processes could be a low-cost sorbent for selective removal of certain metals and metalloids from brine. In this study, continuous-flow sorption processes and factors affecting sorption of boron (III), copper (II), chromium (VI), lead (II), and selenium (VI) from reverse osmosis (RO) concentrate were investigated using different types of i...
