Algal Bioprocess Development for Sustainable Wastewater Treatment and Biofuel Production
(2017-11-24)Rapid urbanization has led to the generation of enormous wastewater after independence. The domestic wastewater generated in municipalities is rich in nutrients such as carbon, nitrogen and phosphorus along with other ions. ... -
Algiculture - A Novel Algae Cultivation Technique for Sustinable Algal Biofuel Production and Capture of Green House Gases
Algal biofuel has been shown to have great potential to solve the World’s sustainable energy crisis but technologies for large-scale cultivation are still elusive. While photobioreactors meet very high value algal products ... -
Anaerobic digestion characteristics of lignocellulosic feedstocks under solid-state stratified bed mode of fermentation
Lignocellulosic feedstocks have become potential materials for conversion to biomethane but possess varying compositions and densities (18-50kg/m3), requiring alternative approaches for evolving sustainable anaerobic ... -
Assessment of Environmental Issues And Biodegradation Aspects of Current MSW Practices of Developing Country Metropolises - A Case Study of Bangalore
(2017-10-18)Municipal solid waste (MSW) production has significantly increased in the rapidly urbanizing developing world and also changed composition with increased decomposable organic fraction in MSW (OFMSW) and plastics content. ... -
Autoflocculating Mixotrophic Algal Consortia Approach to Sustainable Wastewater Treatement
(2017-10-26)The phenomenon of rapid algal blooms in response to nutrient overloads has been adapted to treat synthetic domestic wastewater. Various algal consortia collected from several eutrophied water bodies were subject to high ... -
Biodiesel from Estuarine Microalgae - Diatoms
Rapidly depleting fossil fuel reserves with the burgeoning demand, associated escalating GHG footprint, and changes in the climate necessitated the exploration of alternate sustainable energy resources that are renewable, ... -
Biofilm Reactors for Greywater Treatment
Greywater (GW) is the fraction of wastewater discharged in houses that has not been contaminated with faeces. The average volumes of greywater generated in the households of Bengaluru varies between 40-70 litres/cap/day ... -
Bioremediation of Mechanically and Biologically Treated Waste Of Bangalore City: An Experimental and Numerical Study
Remediation of the existing MSW dumpsites has received considerable attention these days and there is an urgent need to address this issue in order to maintain the over hygiene of the urban environment. An approach consisting ... -
Climate-resilience of Dwellings in Transition and the Thermal Behaviour of their Inhabitants
Thermal comfort is critical for the well-being, and productivity of the inhabitants. Traditional dwellings constructed using local, low-carbon materials have for decades provided comfortable indoor thermal environment to ... -
Contaminated Site Investigation and Remediation Using Modified Nano Zero Valent Iron Particles
Rapid industrialization has boosted economic growth but also increased contaminants in air, water, and soil. Improper disposal of municipal solid waste and industrial effluents has rendered many groundwater sources unfit ... -
