Assessment of performance wastewater treatment by infiltration-percolation: a case study

Abstract

The recycling of wastewater is felt like a need, on the one hand to protect the receiving mediums and on the other hand, to be re-used for various uses (refill of the groundwater, irrigation….). To allow the development of the treatment of wastewater, the infiltration percolation can in this context, to represent an interesting alternative. This technique of purification combined with the Anaerobic Engine with Submerged Bacterial Bed (RALBI) developed at the point by laboratory BIOMARE of the Faculty of Science of El Jadida has for increasing the performances of treatment of the known as engine.

The results of the complementary treatment by the infiltration-percolation made it possible to remove the effluent from engine RALBI from its suspended matter and to decrease its organic, nitrogen, and phosphor load and of its microbial flora. The averages of results of specific analyses are all in lower part of the thresholds of reference.
