Enhanced ultrafiltration by the addition of poly(ammonium acrylate), with two average molecular weight 8000 Da and 15 000 Da, for the removal of Cd(II) from aqueous solutions has been studied. The solution is processed by ultrafiltration using a membrane with pore sizes (10 kDa) small enough to bloc

The wide variability in the agronomic behaviour of the olive tree varieties with respect to the irrigation by treated wastewaters is an indicator of the genetic diversity of the olive tree in our country and of its adaptation to this cropping mode. On the agronomic plan, the results obtained show th

The presence of organic toxic solutes in industrial wastewater is a common environmental problem. Aniline is known to be a harmful and persistent pollutant and its presence in wastewater requires treatment before disposal. The performance of reverse osmosis to remove aniline from aqueous solutions i

Physical, chemical and biological methods have been described to remove phenolic compounds. None of them are the definitively solution of the environmental problem caused by the discharge of this pollutants. Hybrid processes that combine pressure driven membrane processes with adsorption processes h

This study aims to find a new die purification for wastewater reuse. It consists of the filterability of biological sludge exits of the wastewater treatment plant at Staoueli (Algeria) on porous membranes. The membrane used is a mineral membrane M2 Carbosep (15 Kg/mol). we are interested for the fir

This work deals with the feasibility of an olive vegetation wastewater purification process consisting of two consecutive steps: coagulation followed by membrane separation. The target of this work was to reach a purification grade of the wastewater compatible with the limits for the discharge into

The removal of zinc from synthetic wastewater was conducted by micellar-enhanced ultrafiltration (MEUF), using the anionic surfactant sodium dodecyl sulfate (SDS). A two-level full factorial design was used in order to analyze the effect of pressure, membrane nominal molecular weight limit (NMWL), z

Water consumption in textile processes is very high and moreover a large amount of polluted effluents is generated. Many textile industries perform only a biological treatment of these effluents. In countries with water scarcity, the reuse of the secondary effluents represents an interesting solutio

The increasing contamination of soil and waters with volatile organic compounds, such as halogen derivatives or petrochemical hydrocarbons, poses a serious hazard due to the carcinogenic effect of most of the compounds. Their low concentrations as well as the presence of other hindering substances m

A very great quantity of phosphate present in wastewater, may reach the aquatic environment, and can lead to the pollution of the environment. The phosphate must be removed from domestic and industrial effluents before their dispersion and dilution in the environment. The aim of this paper was to in
