This work treats the leachate from the uncontrolled landfill of Casablanca city using the infiltration-percolation technique. To do this, we carried out a comparative study of the filtrations on different matrices to choose the best filtering medium. We used silt, fly ash, bottom ash, agricultural soil and sea sands from the Casablanca coast. The parameters studied are: Chemical Oxygen Demand (COD), pH and heavy metals. The results obtained from adsorption technique show that these matrices used can be an effective adsorbent for the reduction of physicochemical parameters and the elimination of heavy metals. A revaluation of the filtering sludge made in the field of pottery. The results observed are satisfactory at all levels, whether in the reuse of this liquid waste, in the field of irrigation or the recycling of filter matrices.

The development of new efficient cleaning technologies for the bioremediation of the environment and its cleaning from oil products has become a subject of great interest. Surfactants influence the bioremediation of oil and other organic contaminants through increasing their availability. Since surfactant products of a microbial nature are highly efficient in this respect, they have important advantages over synthetic materials. Being biodegradable, they are ecologically safe. A new washing bioremedy based on surfactant products synthesized microbially from the bacterial strain Pseudomonas sp. PS-17 has been obtained. It contains an unique biocomplex of a glycolipid biosurfactant and an alginate biopolymer and possesses a high surface and emulsifying activity. The washing and antisorptional capacity of this bioremedy has been tested on objects of various natures, viz. bird feathers, animal skins and furs. We have obtained positive results in the remediation of sea sands, birds and animals suffering from ecological catastrophy. It was shown that the bioremedy has mild properties and does not change the structure of the feathers, skins and furs studied. The bioremedy remains active over the temperature range 15–90°C.
