Book Description
Contains over 1,100 literature citations through 1992 related to water recirculation and aeration in aquaculture. The focus is on filtration, aeration, and circulation techniques in various aquaculture situations. Provides broad exposure to water quality, organics removal, invertebrate and algal culture systems, diseases and sterilization, and economics. References on partial recycled systems utilizing waste water treatment processes, and relevant sanitary engineering are also included.

Book Description
Stringent environmental restrictions to minimize pollution from hatcheries and land-based aquaculture facilities in northern European countries have sparked the rapid technological development, investment and innovation in recirculation systems in many parts of the world. In general, aquaculture production affects the environment, but state-of-the-art recirculation methods reduce this effect considerably compared to traditional ways of farming fish. Recirculation systems thereby offer two immediate advantages: cost effectiveness and reduced environmental impact. Recirculation also secures a higher and more stable aquaculture production with less diseases and better ways to control the hatchery parameters that influence fish growth in aquaculture production systems This development is welcome and fully in line with the FAO Code of Conduct for Responsible Fisheries. This guide focuses on the techniques for the conversion from traditional farming methods to recirculated aquaculture and advises the fish farmers on the pitfalls to be avoided along the way. Key features of the guide are: assists farmers to convert to recirculation aquaculture; introduces the technology and the methods of management; advises on good practise shifting to recirculation aquaculture; specifies running a recirculation system, staff education and training; provides case stories from different recirculation projects.

Book Description
The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution—air, water, soil, and noise. Because pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unrealistic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identi?ed: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers formulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to speci?c pollution problems has been a major contributing factor to the success of environmental en- neering, and has accounted in large measure for the establishment of a “methodology of pollution control. ” However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.

Book Description
Protecting the global environment is a single-minded goal for all of us. Environmental engineers take this goal to task, meeting the needs of society with technical innovations. Revised, expanded, and fully updated to meet the needs of today's engineer working in industry or the public sector, the Environmental Engineers' Handbook, Second Edition is a single source of current information. It covers in depth the interrelated factors and principles that affect our environment and how we have dealt with them in the past, are dealing with them today, and how we will deal with them in the future. This stellar reference addresses the ongoing global transition in cleaning up the remains of abandoned technology, the prevention of pollution created by existing technology, and the design of future zero emission technology. Béla G. Lipták speaks on Post-Oil Energy Technology on the AT&T Tech Channel.
