REUSE OF BIOSOLIDS GENERATED IN WASTEWATER TREATMENT PLANTS, TO REDUCE ENVIRONMENTAL IMPACTS THANKS TO RECYCLING. STUDY CASES

Abstract

The constant increase of the world population and the demand of natural resources such
as water, makes an optimal management of biosolids that come from wastewater treatment plants,
is a practice of vital importance and responsibility of the engineer to avoid its impact on the environment, due to the physical, chemical and biological composition, because a bad disposition
of these can affect the flora, the water resource and the fauna and the population in general.
These activities of reuse of biosolids, such as the manufacture of construction materials, the
generation of biogas and vermicomposting, apart from being friendly to the environment, they
generate on the other land an improvement in physical and chemical characteristics of the material,
turning the reuse of biosolids into a viable practice for environmental impact and the subsequent
study of new techniques of reuse.
For a better understanding of the subject is necessary to know how the biosolids are generated, in
the wastewater treatment plants, his composition and the reuse that can be given according to the
current environmental regulations
