Study of the influence of two types of sands of the same origin in the treatment of urban waste water by the process of infiltration percolation [Etude de l'influence de deux types de sables de même origine au cours du traitement des eaux usées urbaines par le procédé d'infiltration percolation]

Remediation of domestic and industrial wastewater is a major concern today. the treatment of these effluents is becoming a headache for engineers and environmental scientists who have proposed various methods such as precipitation,ion exchange,adsorption,membrane filtration,application of microorganisms and biomass. however,it is necessary to have cheap materials to treat large volumes of wastewater. among the systems that provide complete satisfaction and we have used in this work are cited infiltration percolation. this method tracks the purifying power of two dune sands bensergao (agadir region) of the same origin,with different compositions on the one hand and on the other to study the evolution of physico-chemical parameters before and after infiltration (temperature,electrical conductivity,dissolved oxygen,total hardness,calcium hardness).
