Mineralization of diazo dye (Reactive Black 5) in wastewater using recirculated up-flow constructed wetland reactor
(Desalination Publications, 2012)
Application of a sequential anaerobic and aerobic process in a constructed wetland can enhance the treatment performance of textile wastewater. In this study, two laboratory-scale recirculated up-flow constructed wetland ...
Effect of alkali concentration on mechanical properties of kaolin geopolymers
(Foundation for Materials Science and Engineering, 2012)
Alkali concentration is the most significant factor in geopolymerization process that must be taken into consideration during the synthesis of kaolin geopolymers. The kaolin geopolymers were prepared by mixing kaolin and ...
Characteristics of airborne Pm₂.₅ and Pm₂.₅-₁₀ in the urban environment of Kuala Lumpur
(Scientific.Net, 2012-12)
Gravimetric and elemental analyses were conducted at a site in Kuala Lumpur from 2008 to 2010, representing the local air quality of urban and traffic. Eighteen elements were detected by ED-XRF and was further analysed for ...
Performance improvement of torque characteristics using the Multi Type Interior Permanent Magnet motor
(Praise Worthy Prize S.r.l., 2012)
The torque characteristic of the novel Multi Type Interior Permanent Magnet (MTIPM) motor that can be operated as permanent magnet stepper (PMST) and dc brushless motor (BLDC) configuration is presented. It briefly presents ...
The processing, characterization, and properties of fly ash based geopolymer concrete
(Advanced Study Center Co. Ltd, 2012)
In recent years, attempts to increase the utilization of fly ash as a replacement for ordinary Portland cement (OPC) in concrete have increased in significance. Geopolymer concrete does not need the presence of Portland ...
Decolorization of Orange II using an anaerobic sequencing batch reactor with and without co-substrates
(The Research Centre for Eco-Environmental Sciences, Chinese Academy of Sciences, 2012-02)
We investigated the decolorization of Orange II with and without the addition of co-substrates and nutrients under an anaerobic sequencing batch reactor (ASBR). The increase in COD concentrations from 900 to 1750 to 3730 ...
Strength and microstructural properties of mechanically-activated kaolin geopolymers
(Trans Tech Publications, 2012-12)
Kaolin geopolymers exhibit low strength properties due to its plate-like nature which contribute to smaller surface area for geopolymerization reactions. Layered kaolin structure only allows very little, if any, substitution ...
Performance and kinetic study on bioremediation of diazo dye (reactive black 5) in wastewater using spent GAC-biofilm sequencing batch reactor
(Springer Science+Business Media B.V., 2012-05)
Combinations of sequential anaerobic and aerobic process enhance the treatment of textile wastewater. The aim of this study was to investigate the treatment of diazo dye Reactive Black 5 (RB5)- containing wastewater using ...
Photocatalytic mineralization of azo dye Acid Orange 7 under solar light irradiation
(Desalination Publications, 2012)
The objective of this study was to investigate mineralization of hazardous water soluble azo dye Acid Orange 7 (AO7) under photocatalytic process. In this experiment, sunlight was used as the source for UV irradiation and ...
Comparative study on photocatalytic degradation of mono azo dye acid orange 7 and methyl orange under solar light irradiation
(Springer Science+Business Media B.V., 2012-09)
The objective of this study was to investigate and compare the kinetic photocatalytic degradation of mono azo dyes Acid Orange 7 (AO7) and Methyl Orange (MO) under solar light irradiation with titanium dioxide (TiO 2) as ...
