Development of an enzymatic hydrolysis pre-treatment strategy to improve batch anaerobic digestion of wastewater generated in desiccated coconut processing plants

Samarasiri, BKT; Rathnasiri, PG; Fernando, EDR [Conference-Abstract]

Enzymes are biological catalysts that accelerate biochemical reactions involved in biological treatment of wastewater. Commercially processed enzymes such as lipases improve the biodegradation by accelerating the hydrolysis ...
Dynamic modelling and simulation of pilot scale anaerobic digestion plant treating source separated food waste and effect of recycling sludge

Rathnasiri, PG [Conference-Abstract]

This study investigates the effect of recycling sludge and stability of pilot scale anaerobic digestion plant treating organic fraction of source separated food waste. Pilot plant comprises of pre-treatment, anaerobic ...
Effect of biofilm growth in anaerobic reactor treating dairy wastewater

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 ...
Effect of Chemical Oxygen Demand (COD) to Sulfate (SO4-2) ratio on sulfate reduction in anaerobic digestion of sulfate rich wastewater

Samarathunga, IR; Rathnasiri, PG; Hansaka, MAR; Kawinda, UGYS; Ananda, RYB [Conference-Abstract]

Effluents discharged from some industries are both high in chemical oxygen demand. If sulfate is not treated up to the standards before discharging, it will contaminate with the surface or ground water bodies. Although ...
Effect of co-digestion on the lipid inhibition in anaerobic digestion of desiccated coconut wastewater

Anjana, WTC; Jayathunga, P; Rathnasiri, PG [Conference-Extended-Abstract]

Seven anaerobic batch reactors were run varying the Desiccated Coconut wastewater (DC) to Food Waste (FW) ratio at room temperature and the daily gas production and CH4 content was determined. Mono digestion of DC ...
Effect of Influent Volumetric Loading of Skim Latex Wastewater on Anaerobic Sulfate Reduction

Samarathunga, IR; Rathnasiri, PG [Conference-Full-text]

Wastewater generated in skim latex industry is rich in high sulfate concentrations, ammonia and protein. This research study investigates the effect of influent volumetric loading of Skim Latex Wastewater (SLW) on anaerobic ...
Effect of lipid inhibition in anaerobic wastewater treatment : a case study using desiccated coconut wastewater

Samarasiri, BKT; Mihiranga, PAD; Rathnasiri, PG [Conference-Abstract]

Anaerobic treatment processes have been extensively developed for the treatment of various wastewaters containing high concentrations of organic substrates including proteins, carbohydrates and lipids. The desiccated coconut ...
Effect of pH and external electron donor on mesophilic sulfate reduction during start-up of anaerobic digesters treating skim latex wastewater

Samarathunga, IR; Rathnasiri, PG [Conference-Abstract]

Effluent of skim latex industry contains high concentrations of sulfate, together with ammonia, protein and organic matter. This research study investigates the influence of pH and addition of external electron donor ...
Investigation of stability of anaerobic digestion of food waste in a plug flow reactor using mathematical modeling and simulation

Karunarathne, HDSS; Rathnasiri, PG [Conference-Abstract]

Anaerobic treatment has gained wide acceptance as a sustainable technology for treatment of solid wastes and waste water. Recently, novel plug flow reactor system has been installed at few local institutions to treat semi ...
Management of paddy soaking water: as a source for enriched compost making

Mikunthan, T; Balakumar, S; Prabhaharan, M [Conference-Full-text]

The effluents discharged from rice mills do not contain toxic compounds, but continuous discharge in to soil or surrounding water bodies cause adverse environmental effects. Hence, the aim of the research was selected as ...
Potential of Plug Flow Digesters for Biogas Production in the Sri Lankan Domestic Context

Hasangika, WAS; Jaanuvi, S; Karunathilake, HP; Manthilake, MMID; Rathnasiri, PG; Sugathapala, AGT [Conference-Full-text]

Biogas production through anaerobic digestion is widely used to convert domestic and industrial waste into energy. In order to successfully adapt this technology for Sri Lankan domestic usage, it is necessary to identify ...
Potential of plug flow digesters for biogas production in the Sri Lankan domestic context

Hasangika, WAS; Jaanuvi, S; Karunathilake, hp; Manthilake, MMID; Rathnasiri, PG; Sugathapala, AGT [Conference-Abstract]

Biogas production through anaerobic digestion is widely used to convert domestic and industrial waste into energy. In order to successfully adapt this technology for Sri Lankan domestic usage, it is necessary to identify ...
Stability of USAB reactor under shock loads

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. ...
