Biochar-based Barricade and Wetland as an Integrated Landfill Leachate Treatment System

Dabare, K; Wijekoon, P; Cooray, A; Athapattu, BCL; Vithanage, M [Conference-Full-text]

Open dumping of municipal solid waste (MSW) imposes severe environmental threats in which landfill leachate generation is considered as the predominant. This study aims on treating landfill leachate using a pilot scale ...
Detection of benzene in landfill leachate from Gohagoda dumpsite and its removal using municipal solid waste derived biochar

Jayawardhana, Y; Kumarathilaka, P; Weerasundara, L; Mowjood, M; Herath, G; Kawamoto, K; Nagamori, M; Vithanage, M [Conference-Full-text]

Numerous landfill associated volatile organic compounds (VOCs) are emerging concern due to their potential risk of health. Benzene is one of the most common VOCs in landfill leachate. Biochar has bulged as a universal ...
Fluoride releasing kinetics in a weathered bearing biotite gneiss

Madusanka, MHA; Sadanayake, S; Vithanage, M [Conference-Extended-Abstract]

In several regions of the dry zone of Sri Lanka, excessive quantities of fluoride (F-) in groundwater have affected the water quality significantly. Apart from the well-known prevalence of dental fluorosis, Chronic Kidney ...
General Characteristics of Hospital Wastewater from Three Different Hospitals in Sri Lanka

Kumarathilaka, P; Jayawardhana, Y; Dissanayaka, W; Herath, I; Weerasundara, L; Vithanage, M [Conference-Full-text]

The hospital wastewater in Sri Lanka is a particular concern possibly due to the hazardous and toxic nature and its direct discharge into water bodies. Hence, this study focuses the characterization of wastewater generated ...
Heavy Metals in Atmospheric Deposition in Kandy City; Implications for Urban Water Resources

Weerasundara, L; Vithanage, M; Ziyath, AM; Goonetilleke, A [Conference-Full-text]

Atmospheric deposition is a serious issue in the context of biogeochemical cycling of heavy metals (HMs) and the resulting impacts on urban water resources. In this study, dry deposition (DD) and bulk deposition (BD) ...
Investigation of landfill suitability based on semi quantitative risk matrix and GIS

Balasooriya, BMRS; Vithanage, M; Mowjood, MIM; Kawamoto, K; Komai, T; Zhang, M; Herath, GBB; Hara, J [Conference-Full-text]

Open dumping is the most widely practiced method in Sri Lanka to dispose municipal solid waste (MSW) because it is the cheapest and easiest method compared to other methods available to manage MSW.Currently, there are no ...
Lability and Bioavailability of Toxic Heavy Metals in Ratnapura District Gem Sediments, Sri Lanka

Sandanayake, S; Diyabalanage, S; Wijesekara, H; Vithanage, M [Conference-Full-text]

Ratnapura district is composed of alluvial sedimentary gem deposits. These deposits have a variety of gem minerals which may contain toxic heavy metals. In this study, the fate of heavy metals associated with gem minerals ...
Potential of Different Biochars for Glyphosate Removal in Water; Implications for Water Safety

Herath, I; Mayakaduwa, SS; Vithanage, M [Conference-Full-text]

We investigated the potential of two different types of biochars (BCs), a waste by product from a Dendro bioenergy industry (DBC) and a steam activated rice husk derived biochar (SRBC) to remove glyphosate from aqueous ...
Preparation and characterization of dendro biochar-hydroxyapatite composite: a potential material for defluoridation

Rathnayake, A; Hettithanthri, O; Rajapaksha, AU; Vithanage, M [Conference-Full-text]

Hydroxyapatite (HAP) is a recognized material for fluoride adsorption; however, dissolution in acidic pH is a disadvantage, while dendro biochar (DBC) is a byproduct from dendro power plants in Sri Lanka. The objective of ...
Propensity and appraisal of biochar performance in removal of oil spills: A comprehensive review

Madhubashani, AMP; Giannakoudakis, DA; Amarasinghe, BMWPK; Rajapaksha, AU; Kumara, PBTP; Triantafyllidis, KS; Vithanage, M [Article-Full-text]

Recently, the adsorption-based environmental remediation techniques have gained a considerable attention, due to their economic viability and simplicity over other methods. Hence, detailed presentation and analysis were ...
Trace metals in the atmospheric deposition and gaseous emissions around Karadiyana municipal solid waste dumpsite, Sri Lanka

De Silva, S; Wijekoon, P; Vithanage, M [Conference-Full-text]

Municipal solid waste accounts for ambient air pollution through heavy metals in atmospheric deposition and greenhouse gases. In the current study, heavy metal pollution was estimated by analyzing dust samples collected ...
