Photodegradation of the antihistamine cetirizine in natural waters

by John Wiley & Sons, Ltd.  (Jul. 18, 2014)

The photodegradation rate of the anti‐histamine cetirizine (Zyrtec®) was investigated in various water matrices. The average observed first‐order photodegradation rate coefficient (kobs), obtained by linear regression of the logarithmic‐transformed cetirizine concentrations versus irradiation time in simulated sunlight, was 0.024 h−1 (n = 6; ...

Impact of operating conditions on performance of capacitive deionisation for reverse osmosis brine recovery

by IWA Publishing  (May 28, 2014)

The study aimed at further developing an integrated capacitive deionisation (CDI)-based process to treat reverse osmosis (RO) brine from a water reclamation facility to increase the overall water recovery to more than 90% and to achieve a sustainable operation of the process with optimised conditions. The normalised treatment capacity of ...

Desalination of oil sands process-affected water and basal depressurization water in Fort McMurray, Alberta, Canada: application of electrodialysis

by IWA Publishing  (Dec. 19, 2013)

The high content of inorganic species in water used to extract bitumen from the Alberta oil sands and in the groundwater below the oil sands is an increasing environmental concern. These water matrices require treatment before they can be reused or safely discharged. Desalination of the oil sands process-affected water (OSPW) and groundwater, or ...

RO brine treatment and recovery by biological activated carbon and capacitive deionization process

by IWA Publishing  (Jan. 1, 2011)

The generation of brine solutions from dense membrane (reverse osmosis, RO or nanofiltration, NF) water reclamation systems has been increasing worldwide, and the lack of cost effective disposal options is becoming a critical water resources management issue. In Singapore, NEWater is the product of a multiple barrier water reclamation process from ...

The Desel System – Capacitive Deionization for The Removal of Ions From Water

by Water Environment Federation (WEF)  (May 7, 2007)

Capacitive deionization (CDI) represents a new approach to the treatment of a variety of water/wastewater streams contaminated with inorganic compounds. ENPAR Technologies Inc. of Canada has developed its DesEL System, which combines high water recoveries with high ion removal efficiencies. The system operates on the principle of capacitive ...

High Purity Boiler Water Production Using Municipal Wastewater at a Combined Cycle Gas-Fired Generating Station

by Eco-Tec Inc.  (Apr. 17, 2013)

The recovery of wastewater for industrial uses presents many challenges for the design and operation of water treatment equipment. Since the term wastewater can be applied to a wide range of water sources from municipal sewage to storm runoff to industrial discharge water, the water characteristics may have great variability. As such, the ...

Current Issues -- Novel, Practical Deionization Technology

by American Water Works Association (AWWA)  (Feb. 1, 2006)

Rapid economic and population growth in the developing world is creating wealth and increasing expectations while simultaneously straining water supply and quality. This situation will reach crisis proportions during the next several decades, and innovative water treatment technologies will be required to meet the challenge. Electrically ...
