This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A preliminary evaluation of the oxidant-enhancement strategy was implemented by providing a 1 mg/L dose of hydrogen peroxide to the biofilter feed over a 2-week test period. The objective was to enhance the oxidative action and response of biofilter microorganisms and to promote the oxidation of inactive biomass. The filter demonstrated ~15 percent removal of filter feed DOC (7 percent less breakthrough than control), and removal of Mn and MIB to non-detect levels. The oxidant enhancement strategy also decreased terminal headloss to a mean 2.2 feet, or ~60% of the control. Both strategies showed enhanced water treatment performance without compromising filter productivity or particulate removal performance.

Download or read book Influence of Water Content, Concentration, and Nutrient Addition on the Biofiltration of Toluene for Air Pollution Mitigation Using Soil Biofilters with Water Content Control written by Daisy B. Badilla and published by GRIN Verlag. This book was released on 2024-02-20 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2011 in the subject Environmental Sciences, grade: Passed, University of the Philippines, course: Doctor of Philosophy in Environmental Engineering, language: English, abstract: In this study, the influence of water content on biofiltration performance was investigated. A biofilter reactor with water content control through changes in matric potential in a suction cell was used to treat toluene-contaminated air with soil as the filter bed medium. Results suggest the soil water content should be controlled at about 96% (dry weight) or a matric potential of -10 cm H2O. The maximum elimination capacity in this study appears to be a restricted to a narrow water content and this narrow range impacts on the operation of full-scale biofilters as traditional techniques for water content control would make maintaining this range difficult. Biofiltration, which is also sometimes referred to as bio-oxidation, is a method of air pollution control where contaminants in a gas stream are metabolized by microorganisms and converted to water, carbon dioxide and biomass. Biofiltration involves biological, chemical, and physical processes. It is often preferred over other air pollution control technologies since it does not produce secondary pollutants and does not involve expensive maintenance and operating costs. However, one of its disadvantages is the difficulty in controlling water content. A water retention curve of the soil was generated by plotting water content versus matric potential with data obtained using the suction cell. Two additional factors, concentration and nutrient addition, were investigated using two other soil biofilters. Improved biofiltration performance was observed at higher toluene concentrations. High toluene concentrations may be advisable during start-up as it converts microorganisms that do not thrive on toluene into nutrients for desired degraders inducing growth and improved performance but would have to be controlled to avoid excessive growth. In the membrane biofilter, the large pores in the biofilm contributed to a possible enhancement of pollutant and oxygen mass transfer. Nutrient addition improved the volumetric removal rate of toluene which implies that available nutrient has been limited. Nitrogen was identified as limiting the biomass growth. The production of carbon dioxide confirmed effective biodegradation of toluene in the soil biofilter. This study contributes to existing knowledge relevant conclusions and recommendations that may guide biofiltration operation, broaden concepts, or direct future studies and it considers treatment of indoor air pollution as a particular area of application.

Download or read book Recent Progress in Slow Sand and Alternative Biofiltration Processes written by Rolf Gimbel and published by IWA Publishing. This book was released on 2006-03-31 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Slow sand filtration is typically cited as being the first "engineered" process in drinking-water treatment. Proven modifications to the conventional slow sand filtration process, the awareness of induced biological activity in riverbank filtration systems, and the growth of oxidant-induced biological removals in more rapid-rate filters (e.g. biological activated carbon) demonstrate the renaissance of biofiltration as a treatment process that remains viable for both small, rural communities and major cities. Biofiltration is expected to become even more common in the future as efforts intensify to decrease the presence of disease-causing microorganisms and disinfection by-products in drinking water, to minimize microbial regrowth potential in distribution systems, and where operator skill levels are emphasized. Recent Progress in Slow Sand and Alternative Biofiltration Processes provides a state-of-the-art assessment on a variety of biofiltration systems from studies conducted around the world. The authors collectively represent a perspective from 23 countries and include academics, biofiltration system users, designers, and manufacturers. It provides an up-to-date perspective on the physical, chemical, biological, and operational factors affecting the performance of slow sand filtration (SSF), riverbank filtration (RBF), soil-aquifer treatment (SAT), and biological activated carbon (BAC) processes. The main themes are: comparable overviews of biofiltration systems; slow sand filtration process behavior, treatment performance and process developments; and alternative biofiltration process behaviors, treatment performances, and process developments.

Available in PDF, EPUB and Kindle. Book excerpt: Hazardous pollutants are a growing concern in treatment engineering. In the past, biological treatment was mainly used for the removal of bulk organic matter and the nutrients nitrogen and phosphorous. However, relatively recently the issue of hazardous pollutants, which are present at very low concentrations in wastewaters and waters but are very harmful to both ecosystems and humans, is becoming increasingly important. Today, treatment of hazardous pollutants in the water environment becomes a challenge as the water quality standards become stricter. Hazardous Pollutants in Biological Treatment Systems focuses entirely on hazardous pollutants in biological treatment and gives an elaborate insight into their fate and effects during biological treatment of wastewater and water. Currently, in commercial and industrial products and processes, thousands of chemicals are used that reach water. Many of those chemicals are carcinogens, mutagens, endocrine disruptors and toxicants. Therefore, water containing hazardous pollutants should be treated before discharged to the environment or consumed by humans. This book first addresses the characteristics, occurrence and origin of hazardous organic and inorganic pollutants. Then, it concentrates on the fate and effects of these pollutants in biological wastewater and drinking water treatment units. It also provides details about analysis of hazardous pollutants, experimental methodologies, computational tools used to assist experiments, evaluation of experimental data and examination of microbial ecology by molecular microbiology and genetic tools. Hazardous Pollutants in Biological Treatment Systems is an essential resource to the researcher or the practitioner who is already involved with hazardous pollutants and biological processes or intending to do so. The text will also be useful for professionals working in the field of water and wastewater treatment.
