Biochemical Conversion of Lignocellulosic Biomass to Ethanol This course describes in detail a potential biochemical ethanol conversion process developed by NREL that converts corn stover to ethanol by dilute-acid pretreatment, enzymatic saccharification, and co-fermentation. The process uses co-current dilute-acid pretreatment of lignocellulosic biomass (corn stover), followed by enzymatic hydrolysis (saccharification) of the remaining cellulose, followed…
Renewable Energy for Water Desalination The United States has abundant agricultural and forestry resources that could be a significant resource for bioenergy. With research, land resources could be effectively used for feedstock production and still meet demand for production of other goods and services. By 2030, about 1 to 1.6 billion dry tons of sustainably…
Biofuels Action Plan The United States has abundant agricultural and forestry resources that could be a significant resource for bioenergy. With research, land resources could be effectively used for feedstock production and still meet demand for production of other goods and services. By 2030, about 1 to 1.6 billion dry tons of sustainably available biomass…
UV Disinfection for Wastewater Treatment This course presents the results of a study that was conducted to determine the long-term benefits and costs associated with three different ultraviolet radiation (UV) disinfection alternatives with respect to chlorination/dechlorination. Chlorination has been the preferred disinfection method used for treating WWTP effluent, but concerns about worker and public safety…
America’s Greatest Projects and Their Engineers VIII Author: Dominic Perrotta This course describes the seemingly impossible mission of the Apollo Program – “landing a man on the Moon and returning him safely to the Earth” by the end of the 1960s. It focuses on several of the key challenges including the need to design components…
Wastewater Forcemain Odor Treatment Author: Michael Kuznetz This course provides an introduction to odor treatment at wastewater treatment facilities. It describes the most common compounds, namely hydrogen sulfate H2S, contributing to corrosion of and the smell emanating from sewer collections systems. It also presents a detailed description and analysis of the most common H2S mitigation…
