Oct 30, 2012 · Two pilot-scale biological sand filters (BSFs) were used to treat artificial wastewater: the first was amended with ethanol and the second with ethanol, inorganic nitrogen (N) and phosphorus (P). A number of biochemical parameters involved in the removal of pollutants through BSF systems were monitored, including effluent chemistry and ...

Jan 1, 2025 · Ethanol, a high-volume low-value product, preliminary produced through a chemical process is now being produced using fermentation considering different low-cost substrates. In recent years, industrialization has increased the amount …

Jun 1, 2018 · In this study, the potential to fully exploit sewage sludge as a raw material for bio ethanol a source of bio fuel is investigated. Sewage sludge hydrolysate was first made by introducing Bacillus flexus in order for saccharification to take place before fermenting to bio ethanol using yeast.

Dec 31, 2023 · Many significant phenolic chemicals and bioactive substances have been extracted from waste during bioethanol manufacturing. The approaches discussed in this study, such as pre-treatment, extraction, and distillation, can enhance the yield of bio-ethanol, which can be beneficial in many ways in the future.

Feb 3, 2020 · This paper characterizes wastewater associated with lignocellulosic ethanol production and evaluates potential wastewater treatment operations. It is found that organic material is intrinsic to bioconversion wastewater, representing up to 260 kg of biological oxygen demand per tonne of feedstock processed.

In this study, the potential to fully exploit sewage sludge as a raw material for bio ethanol a source of bio fuel is investigated. Sewage sludge hydrolysate was first made by introducing Bacillus flexus in order for sacchari cation to take place before fermenting to bio ethanol using yeast.

May 14, 2024 · Also, this same biomass can be transformed into biofuels, such as bioethanol and biohydrogen 9, 10, 11, 12. These biotechnologies could help the country in two important areas: water treatment and...

Oct 31, 2018 · Using sludge derived from treated wastewater as nutrient source, ethanol was produced by certain transgenic species belonging to the genera Proteus. Different forms of sludge were tested for maximal ethanol production, with dehydrated sludge being found to produce the best performance.

Oct 4, 2024 · First-generation bioethanol was typically produced from sugar, starch, or vegetable oil-based feedstock that competed directly with food production. Hence, the requirement of soil, water, and fertilization became a barrier to bioethanol yield.

Jan 4, 2022 · In the present research work, extensive study has been accomplished to determine the potential of peanut shell waste-treated feedstock for bio-ethanol production. Different hydrolysis strategies with process modifications were operated for the improvement in reducing sugar yield that in turn gave better bioethanol production.
