My intent is for the book to contribute to an understanding of the sewer as a chemical and microbiological reactor for the transformation of wastewater, and that the processes within it influence not just the sewer system but the entire urban wastewater system. Chemical and biological processes in wastewater start at the sink and not at the inlet to treatment plants — or in the receiving waters during combined sewer overflows. 

The efficacy of the biological mercury removal process has been adequately demonstrated from a microbiological and biochemical viewpoint. The kinetics of the biological process, bioreactor design and the the effects of process parameters such as aeration rate, SRT and HRT variations on removal of... 

Because of the above, the electron beam process can be used efficiently and effectively as pretreatment for biological processes. The electron beam process can break apart complex organic compounds, making them available for microbiological degradation. 

Microbiological processes in soil water systems are very important because they often control or drive certain soil reactions. For example, one of the parameters that dictates the type and extent of many reactions in soils is pH. The latter, however, is often controlled by biological processes because they either produce or consume acid. The microbial reactions that produce acid include ... 

Article 53 EPC also excludes "plant or animal varieties or essential biological processes for the production of plants or animals this provision does not apply to microbiological processes or the products thereof. 

Manufacturers are beginning to appreciate the breadth and great value of study in this field. The criterion of present day industry is to find the most economical methods of production and to approach as near as possible to complete utilization of all by-products. Microbiology has made many valuable contributions to the industries and it is very evident that many industries based more or less on biological processes will be altered further. Already the relation of fermentation to manufacturing has been emphasized to such an extent that many manufacturing concerns are employing men versed in fermentation to work on their processes and problems. 

The third part of the book deals with soil. Attention is focused on the characteristics of soil and soil components, natural and anthropogenous soil processes, the chemistry, biology and microbiology of soil, and on its analysis with particular reference to fertility and contamination with harmful matters. 

The escape of natural gas from the gas distribution networks also exerts a considerable effect on physical, chemical and biological processes in the soil. The extent of the gas zone depends greatly on the rate of its escape, depth of the groundwater level, type of pipeline, the nature and moisture of the soil, treatment of its surface, etc. The composition of the gaseous phase in the soil is affected by the microbiological oxidation of methane. The rate of this depends on the soil temperature, presence of oxygen and the content of nutrients. At low temperatures, this microbial process is restricted, which also restricts the anaerobic zone.
