Typhoid fever from water desalinized using reverse osmosis

Cyclophosphamide removal from water by nanofiltration and reverse osmosis membrane.

The rejection of cyclophosphamide (CP) by nanofiltration (NF) and reverse osmosis (RO) membranes from ultrapure (Milli-Q) water and membrane bioreactor (MBR) effluent was investigated. Lyophilization-extraction and detection methods were first developed for CP analysis in different water matrices. Experimental results showed that the RO membrane provided excellent rejection (>90%) under all ope...

The Elimination of Toluenediamine from Aqueous Solution by Reverse Osmosis

Toluene diamine (TDA) is a main carcinogenic aromatic pollutant in some industrial wastewater. In this study, the reverse osmosis with DSS-HR98PP as the membrane was employed for the removal of TDA in an aqueous environment. The Box–Behnken Design (BBD) of the experimentwas used to consider the effect of operational variables such as pressure, pH and the feed volu...

Bentazon removal from aqueous solution by reverse osmosis; optimization of effective parameters using response surface methodology

Although bentazon is widely used as an agricultural herbicide, it is harmful to humans and poses many environmental threats. This study focused on the treatment of wastewater contaminated with bentazon pesticides using membrane technology. In this regard, low-pressure reverse osmosis (RO) was employed as it has already been used in the removal of other micro-pollutants. The effects of process v...

Using Reverse Osmosis Membrane for Chromium Removal from Aqueous Solution

In this paper, removal of chromium(VI) from aqueous solution has been researched using reverse osmosis. The influence of transmembrane pressure and feed concentration on permeate flux, water recovery, permeate concentration, and salt rejection was studied. The results showed that according to the variation of transmembrane pressure and feed concentration, the permeate flux and salt rejection we...
