ResumenSe presenta un estudio sobre la reutilización de aguas residuales residenciales en la agricultura. Estas aguas residuales conjuntamente con los residuos sólidos de la construcción civil (RCC) fueron tratadas por decantación y por el método de membranas filtrantes. El lodo decantado proveniente del uso del RCC fue utilizado en la producción de humus. El líquido sobrenadante de la decantación fue tratado por membranas filtrantes y utilizado en la irrigación de suelos recién sembrados. Se observó una germinación rápida del 100% de las semillas, así como una recuperación uniforme del suelo tratado con el humus producido. También se observó una germinación superior al 87% usando el agua reutilizada. En este contexto, los resultados indican que es posible reutilizar los RCC y las aguas residuales residenciales.

These wastewaters together with the compound obtained for construction building waste (CBW) were treated by decantation and by membrane separation processes. The resulting sludge produced by the CBW was used for the production of humus and supernatant water was treated by filtering membrane and reused in irrigation of soils recently seeded. It was observed 100% of seed germination, with fast and uniform growth in soil containing the produced humus. Also, it was observed germination of over 87% using reuse water. In this context, the results show that is possible to reuse domestic sewage and CBW.

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.
