Suresh Indika,Yuansong Wei,Dazhou Hu,Jegetheeswaran Ketharani,Tharindu Ritigala,Titus Cooray,M.A.C.K. Hansima,Madhubashini Makehelwala,Kbsn Jinadasa,S. K. Weragoda,Rohan Weerasooriya +10 more
TL;DR: In this paper, the authors examined RO drinking water stations established by community-based organizations (CBO) in the North Central Province (NCP) and found that the majority (>93%) of RO systems had higher salt rejection rates (>92%), while water recovery varied from 19.4% to 64%.
Journal ArticleDOI
Groundwater-Based Drinking Water Supply in Sri Lanka: Status and Perspectives
Suresh Indika,Yuansong Wei,Titus Cooray,Tharindu Ritigala,Kbsn Jinadasa,S. K. Weragoda,Rohan Weerasooriya +6 more
TL;DR: In this paper , the current status, challenges and opportunities of groundwater quality management and improvement in Sri Lanka were reviewed and discussed, based on previous studies, in order to achieve the 6th goal of United Nations (UN) Sustainable Development Goals (SDG), more efforts are being undertaken to secure drinking water quality.
Journal ArticleDOI
Probing fouling mechanism of anion exchange membranes used in electrodialysis self-reversible treatment by humic acid and calcium ions
M.A.C.K. Hansima,J. Ketharani,D.R. Samarajeewa,K.G.N. Nanayakkara,Ajith C. Herath,Madhubhashini Makehelwala,Suresh Indika,Kbsn Jinadasa,S. K. Weragoda,Yuansong Wei,Yuansong Wei,Rohan Weerasooriya +11 more
TL;DR: In this paper, the authors examined the AEM fouling by Ca2+ and humic acid (HA) using synthetic groundwater using vibrational spectroscopy and found that both inter-and intramolecular interactions, including hydrophobic cationπ interactions among HA-Ca2+ complexes, were active in membrane fouling.
Journal ArticleDOI
A comparative study of community reverse osmosis and nanofiltration systems for total hardness removal in groundwater
J. Ketharani,M. Hansima,Suresh Indika,Dinushi R. Samarajeewa,Madhubhashini Makehelwala,Kbsn Jinadasa,S. K. Weragoda,R. H. W. L. Rathnayake,K.G. Nadeeshani Nanayakkara,Yuansong Wei,Stephen L. Schensul,Rohan Weerasooriya +11 more
TL;DR: In this article , the efficiency of reverse osmosis (RO) and nanofiltration (NF) treatment methods installed in the dry zone (Sri Lanka) were examined as a function of operation parameters, feed and product water quality, membrane type, user maintenance, and wastes handling.
Journal ArticleDOI
Fluorescence characteristics and source analysis of DOM in groundwater during the wet season in the CKDu zone of North Central Province, Sri Lanka.
Dazhou Hu,Suresh Indika,Hui Zhong,S. K. Weragoda,Kbsn Jinadasa,Rohan Weerasooriya,Yuansong Wei +6 more
TL;DR: In this article , the structure, composition, source and spatial distribution of dissolved organic matter (DOM) of two kinds of groundwater samples collected from dug well and tube well in the North Central Province (NCP) during the wet season were determined, compared and analyzed by analytical tools such as parallel factor analysis (PARAFAC).
