Admixtures for use in geopolymers
(2012-11-10)
This study examined two novel approaches for the geopolymerisation of fly ash produced at thermoelectric power stations by combustion of coal. The first approach involved the use of cullet, a post-consumer glass waste, to ...
Integrated solar electrokinetic remediation of soil contaminated with copper
(2012-11-10)
Electrokinetic remediation is an emerging in-situ technology for cleaning contaminated soil. The contaminants are mobilized by passing a low-level direct current between a row of positively charged electrodes (anode) and ...
Chemical and electrochemical modification of kraft lignin to value-added products
(2012-11-10)
Lignin is one of the most abundant biopolymers on earth, constituting approximately 30% of the dry weight of softwoods and 20% of hardwoods. It is a renewable, non-toxic, commercially available and low cost natural resource ...
Effect of carbonation on leachability and compressive strength of cement-solidified and geopolymer-solidified synthetic metal wastes
(2012-11-10)
Stabilization/solidification (s/s) is a well-established technique for treating a variety of
metal-containing hazardous waste streams prior to land disposal. Solidification refers to the improvement of the physical ...
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) ...
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 ...
