Many physico-chemical and operational factors influence the performance, treatment costs, and longterm stability of biofilters for the treatment of wastewater. An innovative role of biofiltration in wastewater treatment plants (WWTPs) focuses on identifying the factors that affect biofiltration, such as the hydraulic retention time of the biofiltration system, the type and characteristics of the filter, and the attached biomass, explains their influence and provides guidelines on how to control these factors to optimize better operation with respect to pollutant control present in (WWTPs). The fundamental basis of the treatment in biofilters is the action of pollutant-degrading microorganisms and consequently the book also discusses in depth about the microbial ecology of biofiltration. In addition, it explores the applications of biofiltration including the removal of emerging pollutants. Describes the microbial ecology of biofiltration Includes modeling of biofiltration Describes the designing of biofilters, start-up, and monitoring Discusses the mechanism of biofiltration Describes the controlling and operational factors of biofiltration

Book Description :

With an increased demand for wastewater reuse, groundwater recharge with treated wastewater has been practiced across the globe. As a result, groundwater quality deteriorates by emerging micropollutants from various anthropogenic origins, including untreated wastewater, seepage of landfill leachate, and runoff from agricultural lands. The fate of such emerging and geogenic contaminants in subsurface systems, especially in the groundwater, depends on several factors. Physicochemical properties of contaminants such as octanol-water partition coefficient, dissociation constant, water solubility, susceptibility to biodegradation under anaerobic conditions, and environmental persistence under diverse geological and pH conditions play a critical role during subsurface mass flow. Thus, advanced wastewater treatment techniques, followed by implementing stricter guidelines, are some of the measures that can safeguard water resources. This book, in general, gives an understanding of the fate and mitigation strategies for emerging and geogenic contaminants in the groundwater. The first and second sections provide a detailed insight into various removal techniques and mitigation approaches. Possible treatment strategies, including bioremediation and natural attenuation, are also covered in those sections. Environmental assessment, groundwater vulnerability, health effects, and regulations pertaining to various contaminants are systematically presented in the third section.

Book Description :

This book highlights advances in sustainable wastewater treatment technologies, particularly biological wastewater treatment, cavitation-based treatment, hybrid water treatment, membrane technologies, advance oxidation processes, and adsorption. The book focuses on a variety of advanced treatment techniques that are useful for the degradation of organic components, dyes, heavy metals effluent, etc. in wastewater. Industrial wastewater consists of variety of discharges based on the type of industry, such as the dairy/food industries, which generate more fats and high BOD value with variation in the pH value, while the electroplating industry may expel more inorganic matter and dissolved solids. The oil extraction industries will have more solvents contained in the effluent, and dyes and textiles industry create a higher organic load with high TDS. Hence, every type of manufacturing industry needs a different method for the treatment of its effluents. Looking at the use of intensified chemical processes in order to make cleaner environment, Innovative Technologies for the Treatment of Industrial Wastewater explores the new and innovative methods for pollutant removal that will prove useful for a variety of industries. Conventional wastewater treatment processes require a significant amount of energy and involve expensive equipment and maintenance. Sustainable wastewater treatment technologies, however, involve less generation of energy and employ more economically feasible treatment methods, requiring less equipment and fewer maintenance costs. Looking at the use of intensified chemical processes in order to make a cleaner environment, this volume explores new and innovative methods for pollutant removal that will prove useful for a variety of industries. This book highlights advances in sustainable wastewater treatment technologies, particularly biological wastewater treatment, cavitation-based treatment, hybrid water treatment, membrane technologies, advanced oxidation processes, and adsorption.

Biofiltration Application at Ethanol Plants

Biofiltration Application at Ethanol Plants Book
Author : Katie Marie Mowat (Donesky)
Publisher : Unknown

ISBN : 0987650XXX
Language : En, Es, Fr & De

DOWNLOAD

Book Description :

The United States used 14.5 billion gallons of the biofuel ethanol in 2019 produced primarily (82%) in dry-mill corn ethanol plants. These plants produce volatile organic compounds (VOCs) — some of which are hazardous air pollutants (HAPs) — during production. Traditional treatment methods for gaseous emissions use a large quantity of water or natural gas. Thus, a bio-trickling filter (BTF) is considered an innovative alternative treatment method. A lab-scale BTF was used in this study to look at the effect of ethanol concentration and temperature on the treatment of a HAPs mixture. Gaseous and aqueous testing were performed on the influent and effluent from the BTF. These tests were also completed on select aqueous streams from within two Nebraska ethanol plants (Plants A and B). This thesis concluded that a mesophilic (21oC) BTF column had a higher removal efficiency for the mixtures tested than a thermophilic (60oC) column due to pH and VOC solubility. As the concentration of ethanol increased the treatment of acetaldehyde decreased and ethanol removal increased by around 25- 35%. This increase may be due to the microbial culture increasing its affinity to ethanol and/or an increase in internal mass transfer of ethanol. It was also found that the microbes had an affinity for VOCs in this order: formaldehyde, ethanol, acetaldehyde, and then methanol. From the aqueous sampling at the two ethanol plants, it was determined that neither of the plants had a stream that met the exact target C:N:P ratio of 200:4:1 that is necessary for use as a nutrient solution in a BTF. Many of the streams also contained chlorine or excess levels of ethanol— both of which are toxic to microbes. Therefore, the nutrient solution used will be either wastewater treatment plant (WWTP) effluent, a waste stream with nutrients added, or well water with nutrients added. Finally, this thesis concluded that in order for Plant B to meet the impurity limits as set by the federal drug administration (FDA) for ethanol plants transitioning into the production of alcohol-based disinfectants, the column tops or the final product process streams will need to be treated further.
