Bacterial cellulose production by acetobacter xylinum in aerated, agitated and attached system

Dissanayake, DMSC [Thesis-Abstract]

Cellulose is the most common biopolymer on earth and has been identified as a major building material of all plants. It is common not only in the higher order plants, but also in microorganisms. Plant Cellulose formed ...
Cfd modeling of a centrifuge for oil - water separation

Thilakarathna, HGSM [Thesis-Abstract]

Centrifugation is an efficient, economical and environmentally friendly method to remove un-desirable water content from oil and water mixtures and separate out the desired oil content.Moreover, the disc stack centrifuges ...
Chemical process route selection based on assessment of inherent environmental hazard, occupational health and safety

Warnasooriya, S [Thesis-Abstract]

Chemical process route selection is one of the main design decisions that needs to be taken during the preliminary stages of chemical plant design and development. A chemical process route is considered as the raw materials ...
Comparison of suitaility of different binding materials in briquette forming

Shyamalee, AMD [Thesis-Abstract]

The process ofmanual saw dust briquette making was tested with different binding agents in the laboratory with 1.5 ton hydraulic jack. Dry cow dung, wheat flour and paper pulp were selected as binding agents. This briquette ...
Conversion of dye sludge to RDF

Rubasingha, SN [Thesis-Abstract]

In Sri Lanka the Dye sludge production from textile industry is large. The large amount of produced dye sludge needs to be properly managed otherwise it will cause lot of environmental problems. Currently textile industries ...
Development of a computational model for biofilm based microbial fuel cell

Marapana, NMNC [Thesis-Full-text]

Studies on Microbial Fuel Cells (MFC) as Power production units are of increasing interest, because it can convert a variety of bio-degradable organic compounds into electricity. In a MFC; biological, chemical and ...
Development of new hybrid adsorption coagulation method for palm oil mill wastewater treatment

Asdullah [Thesis-Full-text]

Activated carbon has been using as an adsorbent for wastewater treatment for decades. It has also been reported that use of fly ash to adsorb impurities in waste water treatment .The main objective of this study is to ...
Development of updraft gasifier and performance analysis for different types of biomass materials

AMIN, M [Thesis-Full-text]

Traditional fossil fuels such as coal, gas and oil are still major candidates to fulfill the energy requirement but their depletion at sharp rate due to increase in demand is at alarming condition. High prices and environmental ...
Effect of drying temperature on the composition of hydro distilled cinnamon bark oil

Kumarage, NDI [Thesis-Abstract]

Cinnamon (Cinnamomum Zeylanicum) is an endemic plant popularly known as “Kurundu” in Sri Lanka. Cinnamon yields mainly cinnamon leaf oil and cinnamon bark oil. Cinnamon bark oil produces by processing dried cinnamon chips. ...
Effect of particle size and secondary air for particulate biomass combustion in a bubbling fluidized bed reactor

Silva GGSN [Thesis-Abstract]

Biomass combustion is used as basic technology to generate heat by humans for millennia. With the incremental needs of modern man, biomass combustion still plays a major role in heat and power generation. In Sri Lankan ...
Effect of particle size on packed bed biomass combustion

Rajapaksha, GDM [Thesis-Full-text]

In this thesis, particle size effect on biomass (rubber-wood) combustion in a packed bed reactor was investigated in experimentally. Mass loss rate, bed shrinkage rate, temperature profile at different bed locations and ...
Effect of ultrasound mixing on esterification of FFA in rubber seed oil

Malliyawadu, MND [Thesis-Abstract]

There is an increasing demand for biodiesel, because of its environmental friendly nature and especially due to the depletion of petroleum reserves. Currently, most of the biodiesel is produced from edible oils under base ...
Implementing a simulator for a process plant with a control system

Piyarathna, WADD [Thesis-Abstract]

Intention of this research study is to develop a simulator with LABVIEW for a reactor/flash/recycle plant which is described in Edgar et al. (2003). The material balances, component balances and energy balances for each ...
Influence of CO₂ injection on biomass updraft gasification process

Lenagala, IRND [Thesis-Full-text]

The utilization of fossil fuels has enabled large-scale industrial development and largely supplanted water-driven mills, as well as the combustion of wood or peat for heat. The burning of fossil fuels by humans is the ...
Investigation of CO2 sequestration possibility via aqueous phase mineral carbonation using industrial waste materials

Nanayakkara SG [Thesis-Abstract]

Carbon dioxide (CO2) as the most vital greenhouse gas in the earth’s atmosphere plays a major role in maintaining the global temperature. Higher concentrations of CO2 in the atmosphere, increases amounts of heat entrapped ...
Investigation of multicomponent heavy metals adsorption capability using raw coir dust and processed coir pith

Amarasinghe AMPC [Thesis-Abstract]

Water is the most vital natural resource that sustains all living organisms on the earth and access to safe and clean water has become a crisis due to intense water pollution by anthropogenic activities, over-pumping of ...
Investigation of stability of plug flow anaerobic digester using mathematical modeling

Karunarathne, HDSS [Thesis-Abstract]

Anaerobic treatment has gained wide acceptance as a sustainable technology for treatment of solid wastes and waste water. But in the local context this technology is not rapidly advancing due to process failures and poor ...
Investigation of temperature profiles of traditional puta and preparation of chalcopyrite ash for ayurvedic treatment using muffle furnace

Pathiraja, PMYS [Thesis-Full-text]

Bhasmas (ashes) are complex compound forms of metals, minerals or gemstones obtained after a series of ayurvedic pharmaceutical preparation processes; purification (shodhana), trituration (bhavana) and incineration (marana) ...
Kinetic modeling of tar formation in an updraft biomass gasifier

Jayathilake GKM [Thesis-Abstract]

As the depreciation of the fossil fuels in the world, it is obligatory to discover new fuels to the highly industrialized society. With increasing requirements of the energy, it is globally focused on the use of renewable ...
Life cycle assessment of domestic biogas systems

Jayapala, JMGD [Thesis-Full-text]

Different sizes of biogas systems were analysed using Life Cycle Assessment (LCA) in order to find the effectiveness of biogas system as a renewable energy source for domestic use. As a pre requisite for the LCA, sample ...
