Algal-sludge Granule for Wastewater Treatment and Bioenergy Feedstock Generation
Water and wastewater treatments consume 3-4% of energy, while 60% of energy used at the wastewater treatment plant is dedicated to aeration in the activated sludge process. This novel bio-granule called oxygenic bio-granule, proposes to transform wastewater treatment facilities into water resource recovery facilities. The oxygenic bio-granule results...

Method for Reducing Sludge Wasting and Enhancing Bio-hydrogen Generation from the Activated Sludge Process
Treatment and disposal of bio-hazardous sludge accounts for 50-60% of the operational costs at a wastewater treatment plant. To treat this sludge, it undergoes a process involving thickening, conditioning, and dewatering, followed by transport to a landfill or incinerator. In addition to high costs, landfilling and incineration are detrimental from...
