We considered the treatment of secondary effluent by coagulation–adsorption coupled with ultrafiltration. Tests were performed on the secondary effluent of the wastewater treatment plant at Staoueli (Algeria) where the average chemical oxygen demand (COD) was 46 (mg O2/L) and turbidity, 16 NTU. The

A combination of adsorption and nanofiltration (NF) was adopted for the treatment of a textile dyehouse effluent containing a mixture of two reactive dyes. The effluent stream was first treated in a batch adsorption process with sawdust as an adsorbent to reduce the dye concentration of the effluent

Pillared bentonite, a clean and cost-effective adsorbent with high specific areas of 111.3 m2/g and high basal spacing of 1.98 nm, was prepared for the removal of humic acid from water. It is effective for the removal of humic acid with a high adsorption capacity of 537 mg/g, and adsorption is favor

Two natural source waters containing natural organic matter (NOM) with different physical and chemical characteristics were dead-end filtered using five types of membranes having different material and geometric properties. In this study retained dissolved organic carbon (DOC) per unit membrane area

We studied the elimination of fluorides from underground water by adsorption on chitosan followed by e lectrodialysis with the help of the CMX-ACS membranes, After determining the optimal conditions of the defluorudation of a synthetic water by the chitosan extract from the chitin of the pink shrimp

The investigation was undertaken to evaluate the effectiveness of using activated carbon (AC) in conjunction with ultrafiltration (UF) in the removal of methylene blue (MB) from aqueous solutions. The combination of activated carbon with UF in this work was to exploit the high adsorption capabilitie

Zeolite was used as a low-cost adsorbent to evaluate its ability to remove color from textile effluents. The zeolite (clinoptilolite) used in this study is a natural clay mineral from the Gördes region of Turkey. The adsorption of reactive dyes into zeolite was investigated by a series of batch adso

Today more than ever, the protection of health and the respect for the laws of nature are among man’s main preoccupations. One of the main concerns, comes is that of nitrates. However, since about fifteen years in a number of Moroccan regions, as well as in many foreign countries, one sees a continu

Recently because of increasing of environmental consciousness and demands, several discussions about the preservation of natural resources have led to more efforts concerning materials of good selectivity and high sorption capacity [1]. We have developed new composite materials with improved adsorpt
