    Latex processing industry generates wastewater with high sulphate content which is converted into hydrogen sulphide in an anaerobic digester. Disposal of this latex wastewater has created severe environmental and health ...
  • Imalsha, DT; Kumari, WMSS; Walawege, OE; Gunawardena, SHP; Ariyadasa, TU [Conference-Extended-Abstract]
    Microbial fuel cells (MFC) have been gained a considerable attention during past few decades due to its ability to treat wastewater effluents while generating bioelectricity. In this study anode to cathode area ratio was ...
  • Mahar, MMM; Nizmy, MNM; Gunasekara, M [Conference-Extended-Abstract]
    In this effort, the batch reactive distillation performance was studied by the production of butyl acetate in a batch packed bed reactive distillation column. Esterification of butan-1-ol with acetic acid to produce butyl ...
  • Eranga, KS; Fernando, GVDL; Rathnasiri, PG [Conference-Extended-Abstract]
    Anaerobic digestion is a key area in wastewater treatment. Especially in treating high concentration wastewater such as dairy wastewater. It is crucial because dairy waste water can change in COD and BOD values drastically. ...
  • Maduwanthi, MKC; Nuwanthika, WHC; Withanage, PK; Ariyadasa, TU [Conference-Extended-Abstract]
    Microalgae have been identified as a potential source for biofuel production by the researches. Cell disruption and chlorophyll removal of microalgae biomass are the most critical factors, which determine the lipid extraction ...
  • Madushan, DPL; Thathsara, PDT; Subasinghe, T [Conference-Extended-Abstract]
    The conversion of biomass to chemicals on an industrial scale at a competitive cost requires the development of biorefineries analogous to petrochemical refineries. Hydroxymethylfurfural (HMF) is a promising platform ...
  • Perera, RACD; Madushika, MHG; Anupama, KADU; Amarasinghe, BMWPK [Conference-Extended-Abstract]
    Coconut shell (CS) charcoal is a potential low-cost adsorbent. Ni(II) and Zn(II) ions in wastewater removal by adsorption is studied in the research using CS char. Results showed that, the maximum adsorption capacity for ...
  • Fernando, MAS; Hansika, NPS; Ariyadasa, T [Conference-Extended-Abstract]
    Haemotococcus pluvalis is a microalgae specie which is recognized as a potential source of astaxanthin accumulation. By selecting two governing cultivation parameters in the form of illumination and initial phosphorous ...
  • Fernando, MKS; Rajapaksha, UBD; Gunasekara, M [Conference-Extended-Abstract]
    The hydrolysis of ethyl acetate is an important reaction in process engineering applications. In industrial scale the reaction is carried out under presence of homogeneous acid catalyst which leads to several environmental ...
  • Eranda, JADV; Kalpani, WHA; Darshana, WAC; Rathnasiri, PG [Conference-Extended-Abstract]
    In this study, attention was given to anaerobic digestion of dairy wastewater, which has higher COD levels and a nutritional rich media for microbial growth. Generally, Fixed Bed Biofilm Reactors are significant in treating ...
  • Attanayake, DDS; Senarathana, NACJD; Madushanka, DR; Gunasekara, M [Conference-Extended-Abstract]
    Quantification of risks has become an indispensable element with modern day systems as it provides an insight into the magnitude of the probable loss prior to the commencement of projects. A methodology for quantifying the ...
  • Abesekara, MS; Kosvinna, KNR; Amarasinghe, BMWPK [Conference-Extended-Abstract]
    Heavy metals in wastewater can be removed by several methods including adsorption. Activated carbon (AC) is widely used, but expensive adsorbent. Since AC derived from coconut shell (CS) is a good adsorbent, coconut shell ...
  • Peiris, ATDN; Sanjeewa, GIN; Gunawardena, SHP [Conference-Extended-Abstract]
    Batch experiments were conducted to investigate the possibility of using Chitosan, a bio polymer for the removal of fat originated from coconut milk. Identification of optimum parametric conditions for fat adsorptivity was ...
