Thermophilic anaerobic membrane bioreactor for pulp and paper sludge treatment
(2018)
Pulp and paper mills generate a significant amount of organic waste (primary and secondary
sludge) that requires treatment and disposal. Currently, pulp and paper sludge (PPS) is either
dried for incineration or used for ...
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 ...
Understanding aging impact on membrane structure and seasonal variation of natural organic matter in water from a membrane drinking water treatment plant
(2018)
An autopsy of hollow fiber (HF) PVDF membrane samples at different ages from a full-scale drinking water treatment was performed to investigate the membrane aging impact on membrane structures and properties. Scanning ...
Assessment of hydrological drought in Northern Ontario using standardized streamflow index
(2018)
Momentum is gaining for the use of a Standardized Streamflow Index (SSI) for the assessment
of hydrological drought, which is an extension of the well-established and popularly used
meteorological drought ...
Comparison between thermophilic and mesophilic membrane-aerated biofilm reactors- a modeling study
(2018)
Membrane aerated biofilm reactor (MABR), as a novel biological waste treatment technology,
has received much attention in recent years, due to its advantages, as compared to conventional
biofilm. Considerable amount of ...
Carbon bio-sequestration by anhydrase enzyme extracted from spinach (Spinacia oleracea)
(2018)
Demand for sustainable and new technologies striving for sequestration of greenhouse gases, particularly carbon dioxide, is an area of considerable focus. In recent years there has been an increased interest in using an ...
Enzymatic hydrolysis of primary paper mill sludge and fermentative production of microbial lipids
(2018)
Canada is known for its abundant forests and thriving forest products industry. For every ton of paper produced in mills across the country, approximately 30 kg of dry primary sludge is produced. The dry sludge is then ...
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 ...
Mesophilic submerged anaerobic membrane bioreactor for pulp and paper secondary sludge treatment
(2018)
The production of pulp and paper is associated with the generation of large quantities of wastewater that has to be purified to avoid severe pollution of the environment. Wastewater purification in pulp and paper mills ...
