Hybrid Lagoon System Technical note (1)
The securement of a source of clean water is a necessary condition for the maintenance of human life, and history demonstrates it to be of fundamental importance for the formation of urban communities and the development of culture. However, only in recent years has it become apparent that, once used by man, unclean water may give rise to epidemics or wreak havoc on the environment, which we need to survive? It is also only recently that we have learned that microorganisms have, over a period of three billion years, been responsible for formation of the atmosphere, generation of the organic material in the soil, and production of clean water, all from the inorganic matter of the primitive earth. Hence microorganisms have played a major role in the emergence of today's world, temperate and teeming with life.
Having learned through experience that microorganisms in water and clinging to dirt and rocks act to cleanse water soiled by other living organisms, human beings at last had the idea of scientifically applying this action of microbes, and after much trial and error built up the present science of sanitation and constructed systems for treatment of waste water. Still, a number of problems remain, and society has imposed new demands, relating to advanced energy-efficient processing (denitrification, dephosphorization) and automatic control of current wastewater processing systems.
In light of this, it is my sincere hope that this manual on LLSB activated sludge treatment, which offers exceptional features and performance even while requiring only simple facilities, will promote a deeper understanding by the reader of today's technology for waste- water treatment, and enable a clear grasp both of current problems and of future solutions.
