  • Comparative performance of bio filter packing materials for waste gas treatment 
    Wijayawardhana, AJ; Wijeyekoon, SLJ; Walpalage, S; Amarasinghe, ADUS [Conference-Extended-Abstract]
    A study was conducted to evaluate the removal efficiency of NH3 and H2S emitted from an industrial waste gas source by biofiltration. Four types of packing material were used and NH3 and H2S in the contaminated air stream, ...
  • Full scale bio filter ammonia removal performance during filter maturation 
    Wijayawardhana, AJ; Wijeyekoon, SLJ; Walpalage, S; Amarasinghe, ADUS [Conference-Extended-Abstract]
    An industrial bio filter of 23 m3 in capacity, packed with a coconut fiber filter medium inoculated with compost of 12 m3 in volume was operated for a period of 45 days. Performance was monitored at gas flow rates of 1160 ...
  • Reinforcement of natural rubber latex films with surface modified silica 
    Liyanage, NMVK; Walpalage, S; Somaratne, MCW [Conference-Extended-Abstract]
    The surface of silica particles was modified by treating with a polymer containing both hydrophilic and hydrophobic monomer units. Surface modification involved esterification of the surface hydroxyl groups with the carboxyl ...
