Bipolar Membrane Electrodialysis for Ammonia Recovery
Supervised by Dr. Jongho Lee
Study of the recovery of gaseous Ammonia from wastewater using a three compartment Bipolar Membrane Electrodialysis system. -
Development of an adsorbent material to remove Fluoride from water
Supervised by Prof. K.G.N. Nanayakkara
Developed a novel chitosan-biochar composite adsorbent material to remove fluoride from groundwater. Besides, a comparative study was done with raw chitosan powder. Fluoride sorption equilibrium was reached after 1 hour with an excellent removal efficiency of 90% for modified adsorbent while raw powder only exhibited a removal efficiency of 16%.
Project Thesis -
Design of a new bridge to reduce traffic congestion in Peradeniya junction
Supervised by Dr. D. De S. Udakara, Dr. G.M.P.R. Weerakoon, Dr. H.D. Yapa, and Mr. D.D. Dias
Designed a new two-lane prestress concrete bridge parallel to the existing Peradeniya Bridge to mitigate the traffic congestion in the Peradeniya junction. The bridge design was done using Autodesk Structural Bridge design 2019 software.
Project Thesis -
Investigating industrial waste treatment procedures in a brewery industry
Supervised by Prof. K.B.S.N. Jinadasa
Brewery waste treatment procedure in Heineken Lanka Pvt. Ltd. was observed and analyzed to investigate the existing treatment facilities. Besides, new improvable methods were suggested to the treatment system and possible difficulties were addressed.
