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 ...
Electrokinetic barrier and remediation with solar energy
(2012-11-10)
Electrokinetics is a promising technique to prevent / minimize the migration of pollutants to the soil and/or groundwater and to remediate contaminated slurries. Electrokinetics requires a low-level direct current (dc) ...
Characterization and utilization of fly ash derived from the co-combustion of biomass and coal as a mineral admixture for ordinary Portland cement
(2009)
Co-firing coal with renewable/waste biomass for power generation can mitigate the atmospheric discharge of pollutants (e.g., SO2) and green-house gases. Wide-spread application of this technology is impeded, however, by ...
Fish biomonitoring in an industrial environment : the Toxicity Early Warning System (TEWS)
(2009)
Industrial, agricultural and municipal effluent discharge into receiving waters continues to be a significant environmental problem. Currently, industrial effluent quality is assessed using chemical assays or by evaluating ...
Effects of feed and operating conditions on the performance and membrane fouling of a submerged anaerobic membrane bioreactor
(2012)
Anaerobic membrane bioreactors (AnMBRs) have been recognized as an effective method for enhanced wastewater treatment and re-use. However, the loss of the membrane performances due to membrane fouling remains a major ...
Production of bio-crude from forestry waste by hydro-liquefaction in sub-/super-critical methanol and upgrading of bio-crude by hydro-treating
(2009)
Bio-energy is renewable and clean (with trace amount of sulfur and neutral in terms of CO2 emission), and abundant in resource, thus it could be a securable and sustainable energy for future. Due to the declining reserve ...
Modeling the transport of Escherichia coli through the subsurface environment
(2009)
Subsurface microbial transport is an important concern in many engineering projects. Expanding the knowledge of this process is important for the risk assessment of sites capable of releasing pathogenic bacterial species ...
Lignin-based hydrogels
(2017)
Currently, limited information is available on lignin-based hydrogels, but its potential in commercial applications presents a promising avenue for the utilization of lignocellulosic materials. Recent studies have employed ...
Source tracking of escherichia coli in a freshwater lake in Northwestern Ontario (Boulevard Lake, Thunder Bay)
(2013-02-01)
Escherichia coli is regularly used as a fecal indicator bacteria (FIB) in recreational waters but its persistence in the environment brings its use into doubt. A secondary FIB known as Bacteroides has been under a lot of ...
Investigation on liquid-liquid dispersion in stirred tanks through experimental approach and computational fluid dynamic (CFD)
(2019)
Stirred tanks have a vital role in chemical engineering industries. Among the various
applications of stirred tanks, mixing of two immiscible liquid phases is of interest in chemical
processes. Mixing of two immiscible ...
