Industrial Waste

This book is intended to fulfil the need for state-of-the-art development on the industrial wastes from different types of industries. Most of the chapters are based upon the ongoing research, how the different types of wastes are most efficiently treated and minimized, technologies of wastes control and abatement, and how they are released to the environment and their associated impact. A few chapters provide updated review summarizing the status and prospects of industrial waste problems from different perspectives. The book is comprehensive and not limited to a partial discussion of industrial waste, so the readers are acquainted with the latest information and development in the area, where different aspects are considered. The user can find both introductory material and more specific material based on interests and problems. For additional questions or comments, the users are encouraged to contact the authors

Evaluation of bacteriophage and viral persistence during alkaline stabilization in sludge and biosolids intended for land application

The use of lime to reduce or eliminate pathogen content is a cost-effective treatment method currently being employed in many Class B biosolids production plants in the United States. A bench scale model of lime stabilization was designed to evaluate pathogen persistence. The survivability of poliovirus type 1, fecal coliforms, Salmonella, adenovirus type 5, rotavirus Wa, and the male-specific bacteriophage MS-2 was evaluated under lime stabilization conditions in various matrices. Salmonella and fecal coliforms were evaluated at 28°C and poliovirus and MS-2 were evaluated at both 28°C and 4°C for survivability under lime stabilization conditions in a sludge matrix. All microorganisms evaluated were discovered to be below detectable levels following twelve hours of liming for all temperatures evaluated. Adenovirus type 5, rotavirus Wa, and MS-2 were evaluated in water, biosolids, previously limed and raw sludge and biosolids matrices at 28°C and 4°C. In all matrices evaluated, adenovirus type 5, rotavirus Wa and MS-2 were below detectable levels following a twenty-four hour incubation with lime, with inactivation rates varying depending on the sample matrix evaluated. Evaluation of reliable and cost effective treatment processes to demonstrate sufficient inactivation of pathogens provides valuable information for implementation of treatment technologies. This research has demonstrated that lime stabilization is effective at reducing fecal coliforms and Salmonella in a sludge matrix at 28°C, poliovirus in a sludge matrix at 28°C and 4°C, and adenovirus type 5, rotavirus Wa and male-specific bacteriophage in sludge and biosolids matrices at 28°C and 4°C when calcium hydroxide was added to achieve a pH of 12 for 2 hours and 11.5 for 22 hours. The similar inactivation of MS-2 under lime stabilization conditions, and prevalence and ease of recovery in sludge samples, combined with the need for a representative indicator in the absence of adequate methodology for recovery and detection of enteric viruses in sludge and biosolids makes male specific bacteriophages a suitable indicator as an index for enteric viruses, to be used for the monitoring of biosolids to determine treatment effectiveness following lime stabilization

Controlled Ecological Life Support Systems: Natural and Artificial Ecosystems

The scientists supported by the NASA sponsored Controlled Ecological Life Support Systems (CELSS) program have played a major role in creating a Committee on Space Research (COSPAR) section devoted to the development of bioregenerative life support for use in space. The series of 22 papers were sponsored by Subcommission F.4. The papers deal with many of the diverse aspects of life support, and with outgrowth technologies that may have commercial applications in fields such as biotechnology and bioengineering. Papers from researchers in France, Canada, Japan and the USSR are also presented

The theoretical bases of chemistry and water preparation technology

The discipline «The theoretical bases of chemistry and water preparation technology» belongs to the cycle of academic disciplines by free choice. It is administrated for depth education of students by the specialty «Chemical technologies of inorganic substances and water treatment». Academic material bases on main regularities of water properties by different origin; knowledge of requirements, nominated for treated water. Teaching of academic discipline «Theoretical bases of chemistry and water preparation technology» occupies important place in formation of future specialists. Its strategy is in approach on deep relation to theoretical postulates with its perfective embodiment due to choosing of real, rational scheme of water preparation
