Aerobic Wastewater Treatment Processes: History and Development
discusses the widely differing influences on the development of
aerobic treatment such as water supply, toxic trade effluents,
microscopy and population growth in urban areas. It covers the
historical development of sewage treatment and the emergence of
aerobic biological treatment from the early nineteenth century to
the present day. The importance of water supply and the influence
this had on the water-carriage system is examined, as is the
consequent discharge of sewage into rivers. The factors which
govern process selection and process development are discussed.
There is a continued impetus to reduce land area, capital costs,
running costs, and to optimise performance and process control. The
discovery of the activated sludge process is detailed including the
development, in the early 1900s, of many forms of this process.
Industrial wastes were discharged to biological treatment systems
and the impact of such pollutants is reviewed. The work of Royal
Commissions, River Boards and the National Rivers Authority is
summarised, and the advances in chemical analysis and "on-line"
measurement of chemical quality characteristics. Later developments
such as reed beds and the use of hybrid treatment systems are
covered. Examples are included such as the "fixed film" activated
sludge process which has found application for small communities in
package form, and also for large-scale municipal treatment plants.
Aerobic Wastewater Treatment Processes: History and Development is
valuable reading for students of the following courses on CIWEM Dip
examination, WITA and B Tech and Environmental Science and Civil
Engineering.
