This book was released on 2011 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excess nitrogen and phosphorus in discharged wastewaters can lead to downstream eutrophication, ecosystem damage, and impaired water quality that may affect human health. Chemical-based and physical-based technologies are available to remove these nutrients; however, they often consume significant amounts of energy and chemicals, greatly increasing treatment costs. Algae are capable of removing these pollutants through biomass assimilation, and if harvested, can be utilized as a feedstock for biomethane or biodiesel production. Currently, difficulties in harvesting, concentrating, and dewatering algae have limited the development of an economically feasible treatment and production process. When algae are grown as surface-attached biofilms, the biomass is naturally concentrated and more easily harvested, leading to less expensive removal from treated water, and less expensive downstream processing for biofuel production. In this study, a novel algal biofilm production and harvesting system was designed, built, and tested. Key growth parameters were optimized in order to maximize biomass production and nutrient uptake from wastewater. Compared to suspended algae systems, the attached algal biofilm design of this study led to increased biomass production and greater treatment of domestic wastewater. An efficient and inexpensive algal biofilm harvesting technique was also developed in order to obtain a concentrated biosolids product, resulting in improved water quality and a feedstock suitable for further processing in the production of biofuels.

Download or read book Algal Biorefinery written by Gulshan Kumar Sharma and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the recent years, due to heavy surge in the price of petrochemical products, researchers are getting interest towards renewable bioenergy resources such as algal-based biomass. In order to meet a world energy demand, current bioeconomy challenges and to produce valuable products, intensive and integrated research on algal biorefinery is highly required. Even though several research carried out study for the conversion of algae biomass to biofuel, but none of these proved economically viable. Hence, range of value added product (biodiesel, biochar, fertilizer, etc.) must be produced subsequently from algae. The utilization of microalgae for biomass production is better than agricultural crops as microalgae do not required fresh water for its growth, it can readily grow on wastewater throughout the year. Generation of wastewater is severe concern throughout the world and discharge of wastewater without proper treatment in to water bodies causes water pollution. Microalgae bear vast potential in significantly deescalating pollutant load (nitrate, TDS, ammonium, phosphate, organic load) from wastewater. The harvested algal biomass after remediation has significance role in producing biofuels and by-products in a sustainable way. In this chapter, emphasis would be given on role of algae in wastewater treatment and its biorefinary approach for sustainable energy development.

This book was released on 2022-06-22 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited book provides an account of past, present, and future constraints in microalgae-based biorefineries, emphasizing cultivation and refining processes. The book offers an insight into the recent advancements in the technologies and methods developed microalgae-based biorefinery for bioenergy and biochemicals production. The fast depletion of fossil fuels has forced researchers to move out of reliance on fossil fuels for the industrial and energy sector’s needs. Due to its rich protein and lipid content, microalgal biomass has been considered one of the suitable substrates for the biorefinery. Microalgal production and harvesting for biofuel and chemicals is a tedious task. Several technological advances have been observed in this area, thus systematically checking the viability of technology at laboratory scale and then moving to large scale production, harvesting, extraction, processing, and characterization is the main focus of the book. This book is equally beneficial for researchers and engineers in biomass-based biorefineries or the bachelors, master, or young budding graduate students as a textbook.

Download or read book Microalgal Bacterial Consortia for Biofuel Production and Wastewater Treatment written by Mark Henry Loria (II) and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Microalgae have shown promise as a platform for biofuel production and for providing low-cost nutrient removal from wastewater. The combination of these potential uses of microalgae could allow for energy recovery from wastewater streams. There are multiple approaches to microalgal cultivation, but based on theoretical considerations and previously published results, this dissertation focuses primarily on polyculture microalgal communities and combined microalgal-bacterial consortia. These mixed microbial communities are predicted to be productive and robust to disturbances, key features of a microalgal cultivation platform.High value microalgal biomass production from wastewater requires research on crop protection strategies, microbial community assembly, approaches to biomass harvesting, and operation of reactors for efficient nutrient removal from wastewater. Adequate crop protection is necessary for high biomass productivities and minimization of reactor crashes. Low-cost harvesting strategies will help lower energy inputs into microalgal reactors and increase the economic viability of algae for commercial applications. Finally, it is important that algae cultivated on wastewater produce effluent that is as clean, or cleaner, than traditional activated sludge systems. This dissertation addresses aspects of these key research questions for microalgal cultivation platforms. This includes the investigation of a bioprocess control strategy with the goal of increasing the lipid yield of algal polycultures through natural selection. Additionally, interactions between bacteria and microalgae in microalgal-bacterial systems, and specifically the competition between nitrifying bacteria and microalgae, is examined. The performance of these cultures for nutrient removal from synthetic wastewater was evaluated, revealing luxury N and P removal from wastewater by MAB consortia. Settleability of algal biomass is a key component of wastewater treatment and biofuel production systems, and this parameter was also assessed for the MAB consortia. Preliminary data on microbial invasion of microalgal cultures is presented, with relevance to bioaugmentation of microbial communities with specific microalgae, and to the problem of harmful algal blooms in Lake Erie. These experiments have helped to improve the understanding of how different microalgae and bacteria interact and function within bioreactors, with implications for wastewater treatment and biofuel production. Results reveal several future research directions relating to microalgal-bacterial reactor operation and the underlying ecology of microalgal-bacterial consortia.
