Comparison between the photocatalytic degradation of single and binary azo dyes in TiO2 suspensions under solar light irradiation
(IWA Publishing, 2015-12)
Textile industries discharge a large quantity of colored wastewater which is harmful to the ecosystem. In this study, two kinds of dyes were investigated: the mono azo Acid Orange 7 (AO7) and diazo Reactive Green 19 (RG19). ...
Removal of heavy metal ions from mixed solutions via polymer-enhanced ultrafiltration using starch as a water-soluble biopolymer
(John Wiley and Sons Inc., 2015)
In this study, aqueous solutions containing mixtures of heavy metals namely Zn (II), Pb (II), Cr (III), and Cr (VI) were treated by polymer-enhanced ultrafiltration (PEUF) using unmodified starch as binding biopolymer. The ...
Electrochemical reduction of carbon dioxide into formate
(Taylor's University College, 2015)
The electrochemical reduction of CO2 dioxide into HCOO- on a Sn cathode is well described in literature. However, the issue of deactivation and loss of Sn and a suitable non-aqueous supporting electrolyte remains unresolved. ...
A proposed aerobic granules size development scheme for aerobic granulation process
(Elsevier, 2015-04-01)
Aerobic granulation is increasingly used in wastewater treatment due to its unique physical properties and microbial functionalities. Granule size defines the physical properties of granules based on biomass accumulation. ...
The behavior of internal humidity from fibre optic daylighting system application
(Penerbit Universiti Teknologi Malaysia, 2015-08-25)
Electrical lighting consumed 13% to 43% from overall energy which considered as second major usage of electrical energy in a building. Fibre optic daylighting is a potential approach for the remote source daylighting which ...
Feasibility study on solar power plant utility grid under Malaysia feed-in tariff
(Science Publications, 2015-05-27)
In Perlis, Northern Malaysia, a solar power plant with an energy capacity of 5 MWp began selling energy to Tenaga Nasional Berhad in January 2013. Upon obtaining Feed-in Tariff approval from the Sustainable Energy Department ...
Effects of cationization hybridized biopolymer from Bacillus subtilis on flocculating properties
(Taylor and Francis Ltd., 2015-07-29)
Bacillus subtilis isolated from palm oil mill wastewater was able to produce biopolymer with high flocculating activity in treating kaolin clay suspension (Al2Si2O5(OH)4). Hybridization of the biopolymer with monovalent, ...
Removal of zinc and lead ions by polymer-enhanced ultrafiltration using unmodified starch as novel binding polymer
(Springer Berlin Heidelberg, 2015-06-01)
The removal of zinc and lead from aqueous dilute solutions by polymer-enhanced ultrafiltration process using unmodified starch as a new binding polymer was studied. Experiments were performed to determine the effects of ...
Removal of Ni(II), Zn(II) and Pb(II) from aqueous solutions using cation-exchange resin in fixed-bed column
(Taylor and Francis Ltd., 2015-10-13)
Breakthrough curves for the removal of Ni(II), Zn(II), and Pb(II) from aqueous solutions using cation exchange resin (Dowex 50W) were determined at dynamic conditions in a fixed-bed column under ambient temperature. The ...
Decolorization and mineralization of Batik wastewater through solar photocatalytic process
(Penerbit Universiti Kebangsaan Malaysia, 2015-04-01)
In this study, the photocatalytic degradation of batik wastewater in the presence of zinc oxide (ZnO) as photocatalyst was investigated. The effect of various operating parameters, such as pH of batik wastewater, catalyst ...
