Abstract

The aim of the present study was to obtain the water of reuse from domestic sewage provided by Anhumas Sewage Treatment Station, from Campinas, Brazil. The construction building waste was used in decantation of sludge from sewage. The sewage water was filtered in a membrane of microfiltration and used in irrigation. Bean seeds are used in germination on degraded soils. Ecological cost was measured. Results showed that the membrane separation process demonstrated that is a method very efficiently in the removal of chemical parameters from sewage, what made its reuse. Of accordance to ECA results, the saving with the water of reuse produced in this work; was of US$ 13 million. It is demonstrated that this technology is ecologically and economically viable.
