Landfarming of Oily Wastes: Design and Operation

S. P. Amaral

The technology of treatment through landfarming for oily wastes has been more and more often utilized in Brazil, always successfully.

The definition, the processes which occur, as well as the factors which affect its performance are herein presented.

Design parameters, such as location, ground characterization, dimensioning of the area of application, groundwater protection, drainage, treatment of surface runoff water and percolated liquid, among others, are presented.

Operational procedures and quality monitoring of effluents and environment are also described.

PETROBRÁS is already operating two landfarming systems and has several others in the design stage.

We present data from these projects and report that oily waste degradation has been achieved in around six months.

Finally, we expect to be contributing to the affirmation and development of this technology in our Country.

Keywords: Landfarming; oily wastes; oily residue treatment; biological degradation; waste disposal; soil cultivation process; sludge farming.
