Effects of freezing on UV inactivation of waterbourne microorganisms
(2009)In northern communities where source water may be frozen for parts of the year or wastewater is treated using freezing technology, the efficiency of UV inactivation may be affected. This research was carried out to investigate ... -
Freeze-thaw effect on selected fecal indicator bacteria : Escherichia coli and Enterococcus faecalis / by Nicole A. Hawdon.
(2008)The survival of two selected fecal indicator organisms, two strains of Escherichia coli, a Gram-negative bacterium, and two strains of Enterococcus faecalis, a Gram-positive bacterium, after freezing and thawing successively ... -
The influence of temperature on dynamic membrane structure
(2022)This study investigates the influences of cold source-water temperatures and warm temperature recoveries on the dynamic changes of membrane structure. The morphology of membrane pores on the membrane surface was firstly ... -
Nutrients Recovery from Municipal Wastewater Effluent using Electrochemical and Freeze Concentration Approaches
(2016)Municipal wastewater (MWW) is now being re-evaluated as a potential multi-resource for water, energy and nutrients. Anaerobic membrane bioreactors (AnMBRs) are increasingly being investigated as a cost-effective biological ... -
Pretreatment and conditioning of municipal wastewater secondary sludge using freezing and a combination of ultrasound and freezing
(2014-01-22)With the cost of sludge management on the rise, the volume reduction of municipal wastewater sludge is becoming an increasingly important issue for wastewater treatment plants. Current research is focused on pretreatment ... -
Progressive freeze concentration of naphthenic acids
(2013)Canada’s oil reserves are among the largest in the world with over 1.7 trillion barrels of bitumen in place with confirmed measurements indicating there are 173 billion barrels of recoverable oil under current economic ... -
Removal of pharmaceutically active compounds from water systems using freeze concentration / by Yuanyuan Shao.
(2007)In the last few years, there has been a growing concern in the occurrence of pharmaceutically active compounds in the aquatic environment. Just in Europe, more than 3000 prescription and non-prescription drugs are used by ... -
Reversibility of PVDF membrane performance and structure caused by cold water temperature and elevated conditioning water temperature
(2018)Thousands of dollars are wasted each year due to the impact that cold temperature has on membrane filters. There are many areas around the world that are subjected to cold climate, and the study of how cold temperature has ... -
Toxic and precious metals removal from wastewater using freeze concentration and electrodeionization
(2018)Industrial wastewater may contain metals such as chromium (VI), nickel, cobalt and palladium. These metals are toxic to aquatic organisms and also have an adverse impact on human health and environment. Due to limited ...
