Pages : 350 pages

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.

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 animals and humans. These pollutants also refer as “emerging pollutants” are mostly aromatic compounds which derive from excretion of pharmaceutical, industrial effluents and municipal discharge. Some form of pollutions have also evolved, including the proliferation of acid mine drainage from oxidation or weathering of obsolete and unmanaged excavations around the world; this results mostly in the dispersion of inorganic pollutants in the environment at level surpassing the treatment capacity of conventional techniques. 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. This book 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 development 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

Wastewater Irrigation and Health
Author : Pay Drechsel
Publisher : IWMI
Release Date : 2010
ISBN 10 : 1844077969
Pages : 404 pages

In many countries wastewater treatment systems are hardly functioning or have a very low coverage, resulting in very poor quality water being used for irrigation and the cultivation of consumable produce. This can create significant risks to public health, particularly in expanding urban areas. Wastewater Irrigation and Health approaches this serious problem from a practical and realistic perspective, addressing the issues of health risk assessment and reduction in developing country settings. The book therefore complements other books on the topic of wastewater which tend to target high-end treatment options or merely report that wastewater irrigation is a common phenomenon. The editors of Wastewater Irrigation and Health move the focus onto quantifying risk in order to reduce it. It presents the state-of-the-art on low-cost options for health risk reduction in line with the multiple barrier approach of the 2006 guidelines published by the World Health Organization. The authorship includes a mix of agronomists and engineers who have been working closely with social scientists and health experts, from Africa, Asia, Europe, North America and Australia. The chapters highlight experiences across the developing world with case studies from different parts of sub-Saharan Africa (Ghana, Dakar, Mauritania, South Africa), Asia (India, Pakistan, Vietnam, Bangladesh), Mexico and MENA (Jordan, Tunisia). The book thus clearly establishes a connection between agriculture and sanitation, which is often the missing link in the current discussion on resource recovery.

Doctoral Thesis / Dissertation from the year 2020 in the subject Biology - Miscellaneous, grade: A, National Institute Of Technology Durgapur (National Institute of Technology Durgapur), course: PhD in Biotechnology, language: English, abstract: The present research work was undertaken for the biological treatment of starch industry wastewater for pollution control. Starch industry effluent generates a large volume of wastewater with strong acidity and enormous carbon and nitrogen pollutants. In the present study, the development of low pH methanogens and anammox microorganisms were given special attention. Low pH methanogenic reactor and anammox reactor were fabricated for the biological treatment of corn starch industry effluent. In the first part of the work, low pH tolerant methanogens were isolated from peat bog of leaf debris. It showed the presence of Gram-negative, non-spore forming, and cocci with creamish black colour colonies. The leaf debris inoculum was taken for optimum COD removal under anaerobic conditions. Identification and isolation of anammox group of bacteria were performed using enrichment and 16S rRNA amplicon analysis. The objective of the study was to remove ammonia under the anaerobic condition from starch industry effluent. The media optimization using carbon and nitrogen source was undertaken which is required for anammox enrichment. The physical growth factors like temperature and pH were optimized. The optimized temperature and pH were 39 0C and 7.2 respectively. Some restrictive growth factors like salinity and antibiotic concentration were also studied which were found insignificant in our study. Finally, the overall process was scaled up in the laboratory reactor. The reactor study revealed that in the anaerobic reactor 1.16 kg COD/kg VSS/d was removed producing 42-46% methane as output gas. The anammox reactor was able to reduce 82% nitrogen load from starch industry effluent at the rate of 1.5 kg/m3/d after 568 days of initiation.

Pages : 198 pages

As government and community leaders, private companies, citizens, and applied scientists search for low-cost methods to cleanup environmental pollution, phytotechnologies can contribute to the solution by utilizing natural processes to reduce environmental risk. Phytotechnologies use vegetation to manage environmental contaminants in soil, surface water, and groundwater based on site-specific design considerations that can save 50 to 75 percent of the capital and operating costs compared to conventional remediation and containment technologies. Successful phytotechnology applications are based on scientific knowledge of plant physiology, chemical contaminants, climate, and soil conditions. This book presents current research findings that address soil and water contamination with obsolete pesticides, radionuclides and other inorganic and organic contaminants. This book documents international sharing of information by scientists and stakeholders seeking to use the best available information: to disseminate existing knowledge on phytotechnologies and exchange experience of field-scale applications for cleanup of industrial, agricultural, and wastewater contamination, to assess existing knowledge and identify research needs and directions for future work especially in regard to environmental management in Central and Eastern Europe and Central Asia, and to promote collaboration between different countries in preparing applications for environmental remediation and restoration.
