Research ArticleOpen accessIn the abstractAssessment of Heavy Metals Uptake and Translocation by Aquilaria malaccensis Planted in Soils Containing Sewage SludgeKeeren Sundara Rajoo, Arifin Abdu, Hazandy Abdul-Hamid et al.Increase in human population has resulted in an enormous growth in the volume of wastewater. The conventional methods of sewage sludge disposal, that is the by-product of wastewater treatment, are costly and not environment-friendly. An ideal way for sewage sludge management is by using it as a soil amendment in agricultural land due to sewage sludge’s high organic matter content. … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 7,079 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeavy Metal Uptake and Translocation by Dipterocarpus verrucosus from Sewage Sludge Contaminated SoilKeeren Sundara Rajoo, Arifin Abdu, Daljit Karam Singh et al.Sewage sludge or biosolids is the solid waste that has been left after wastewater is treated in a domestic wastewater treatment facility. The most common way of sludge disposal is to dispose it on the land, sea or air (incineration). However, these methods are not environment-friendly, costly and time consuming that requires expertise and knowledge. An ideal way to manage … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 10 Jul 2013 · 7,819 accessesView PDFCite
