Download Efficacy of Microscale/nanoscale Aqueous Ozone on the Removal of Bacillus Spp. Biofilms from Polyethersulfone Membranes in the Dairy Industry Book in PDF, ePub and Kindle
Biofilm formation on polyethersulfone (PES) membranes in the dairy industry is a concern to food safety and public health. Fouling of PES membranes leads to biofilm formation on membrane surfaces, resulting in reduction in membrane performance and premature replacement of membranes. The dairy industry must develop technology to discourage biofilm attachment, while also finding a more efficient, eco-friendly approach to biofilm removal from dairy processing equipment. Fouling of PES membrane surfaces creates an environment in which bacterial attachment and biofilm formation thrive. Biofilm removal from dairy processing membranes has become a point of interest as cost of producing quality products continues to rise. Experimentation was carried out in two phases. Phase 1 evaluated the half-life of microscale/nanoscale aqueous ozone (MNAO) using a factorial design, with pH (2, 4, and 7) and temperature (5, 10, and 20°C) as independent factors with two replications. After statistical analysis of the half-life study using a completely randomized design, a pH of 4 at 10°C for MNAO was used in further studies. This study then evaluated the efficiency of MNAO on removal of biofilms from PES membranes. Phase 2A first compared the efficacy of a deionized water wash and MNAO on Bacillus cereus and Bacillus licheniformis biofilms grown on PES membranes. MNAO was more effective (p≤0.05) than the water wash with an average reduction of 1.9 log10 cfu/cm2 for Bacillus cereus, and 1.2 log10 cfu/cm2 for Bacillus. licheniformis, respectively. The MNAO membrane wash reduced B. licheniformis counts on membranes by 2.3 log cycles, while the water wash reduced the population level by 1.9 log cycles (p≤0.05). Both the Bacillus cereus and Bacillus licheniformis data were compared to a non-treated control membrane. Phase 2B analyzed the efficacy of a typical clean-in-place (CIP) cycle used in the dairy industry compared to a CIP cycle followed by MNAO wash. Treatment of B. cereus biofilms using a standard CIP protocol or the CIP+MNAO resulted in significant (p≤0.05) population reductions of 3.8 and 4.1 log10 cfu/cm2 respectively. A significant difference was observed when comparing Side A and Side B data (p≤0.05). For Bacillus licheniformis containing biofilms, both treatments provided significant population reductions (p≤0.05) compared to the untreated control. Phase 2C studied the efficacy of a typical CIP system alone in comparison to an MNAO wash followed by a typical CIP system. In the Bacillus cereus and Bacillus licheniformis study, CIP and MNAO+CIP treatments significantly reduced (p≤0.05) population levels of both organisms by 3.4 to 4.7 log cycles respectively; however, the reductions observed for the two treatments within bacteria type were similar (p≤0.05).

Download Nano and Bio-Based Technologies for Wastewater Treatment Book in PDF, ePub and Kindle
Presents recent challenges related to new forms of pollution from industries and discusses adequate state-of-the-art technologies capable to remediate such forms of pollution. Over the past few decades the boom in the industrial sector has contributed to the release in the environment of pollutants that have no regulatory status and which may have significant impact on the health of humans and animals. These pollutants also referred to as "emerging pollutants", are mostly aromatic compounds which derive from excretion of pharmaceutical, industrial effluents and municipal discharge. It is recurrent these days to find water treatment plants which no longer produce water that fits the purpose of domestic consumption based on newly established guidelines. This situation has prompted water authorities and researchers to develop tools for proper prediction and control of the dispersion of pollutants in the environment to ensure that appropriate measures are taken to prevent the occurrence of outbreaks due to sudden load of these pollutants in the water system. The chapters in this book cover a wide range of nano and bio-based techniques that have been designed for the real time detection of emerging contaminants in environmental water sources, geochemical models that are continuously improved for the prediction of inorganic contaminants migration from the mine solid wastes into ground and surface waters. Remediation strategies are also discussed and include effective techniques based on nanotechnology, advanced membrane filtration, oxidative and bio-degradation processes using various types of nanocatalysts, biocatalysts or supporting polymer matrices which are under advanced investigations for their implementation at large scale for the removal of recalcitrant pollutants from polluted water. Nano and Bio-Based Technologies for Wastewater Treatment: Prediction and Control Tools for the Dispersion of Pollutants in the Environment is divided is two sections. The first section covers the occurrence of emerging pollutants in environmental water while the second section covers state-of-the-art research on the removal of emerging pollutants from water using sustainable technologies. A total of 13 chapters addressing various topics related to the two sections are essentially based on recent developments in the respective field which could have a significant impact on the enhancement of the performance of wastewater treatment plants around the world, and especially in developing countries where access to clean and safe water remains a daily challenge.

Download Removal of Emerging Contaminants Through Microbial Processes Book in PDF, ePub and Kindle
The abundance of organic pollutants found in wastewater affect urban surface waters. Traditional wastewater management technologies focus on the removal of suspended solids, nutrients and bacteria, however, new pollutants such as synthetic or naturally occurring chemicals are often not monitored in the environment despite having the potential to enter the environment and cause adverse ecological and human health effects. Collectively referred to as "emerging contaminants," they are mostly derived from domestic activities and occur in trace concentrations ranging from pico to micrograms per liter. Environmental contaminants are resistant to conventional wastewater treatment processes and most of them remain unaffected, causing contamination of receiving water. This in turn leads to the need for advanced wastewater treatment processes capable of removing environmental contaminants to ensure safe fresh water sources. This book provides an up-to-date overview of the current bioremediation strategies, including their limitations, challenges and their potential application to remove environmental pollutants. It also introduces the latest trends and advances in environmental bioremediation, and presents the state-of-the-art in biological and chemical wastewater treatment processes. As such, it will appeal to researchers and policy-makers, as well as undergraduate and graduate environmental sciences students.

Download Bioremediation and Biotechnology Book in PDF, ePub and Kindle
Toxic substances threatens aquatic and terrestrial ecosystems and ultimately human health. The book is a thoughtful effort in bringing forth the role of biotechnology for bioremediation and restoration of the ecosystems degraded by toxic and heavy metal pollution. The introductory chapters of the book deal with the understanding of the issues concerned with the pollution caused by toxic elements and heavy metals and their impacts on the different ecosystems followed by the techniques involved in monitoring of the pollution. These techniques include use of bio-indicators as well as modern techniques for the assessment and monitoring of toxicants in the environment. Detailed chapters discussing the role of microbial biota, aquatic plants, terrestrial plants to enhance the accumulation efficiency of these toxic and heavy metals are followed by remediation techniques involving myco-remediation, bio-pesticides, bio-fertilizers, phyto-remediation and rhizo-filtration. A sizable portion of the book has been dedicated to the advanced bio-remediation techniques which are finding their way from the laboratory to the field for revival of the degraded ecosystems. These involve bio-films, micro-algae, genetically modified plants and filter feeders. Furthermore, the book is a detailed comprehensive account for the treatment technologies from unsustainable to sustainable. We believe academicians, researchers and students will find this book informative as a complete reference for biotechnological intervention for sustainable treatment of pollution.
