The effective removal of heavy metals from aqueous wastes is among the most important issues for many industrialized countries. Removal of lead (II) and copper (II) from aqueous solutions were studied using pomegranate peel (raw), activated carbon prepared from pomegranate peel (AC1) and activated c

Bagasse pith, which is the main waste from sugarcane industry in Egypt, has been used as a raw material for the preparation of different activated carbons. Activated carbons were prepared from bagasse pith by chemical activation with 28% H3PO4 (AC1), 50% ZnCl2 (AC2) followed by pyrolysis at 600°C an

The production of a biosurfactant by Pseudomonas fluorescens Migula 1895-DSMZ was studied. Cultures conditions involving variations in carbon and nitrogen sources and different C:N ratios were examined at constant temperature and pH, with the aim of increasing productivity in the process. Biosurfact

The aim of this paper is to propose an efficient and low-cost treatment of chemical mechanical polishing wastewater process based on electrocoagulation with iron bipolar electrodes. The performance of a pilot scale electrochemical reactor equipped with iron bipolar electrodes and an anode active are

High efficiency activated carbon with different chemical characteristics, appropriate for the purification of waste and potable water with different pollutions (metal ions) was prepared. It was established that activated carbon is obtained from carbonized olive stones in presence of nitrogen in the

Water shortage problem is considered to be one of the biggest problems facing the middle eastern region, specifically the Arab countries located in semi-arid zones. The natural water resources of the region are suffering from outside control dominated by complex political circumstances, and inside d

The aim of the paper was to study landfill leachate treatment efficiency during fermentation process in UASB reactor and post-treatment in RO process. In the first step of experiment, the granular sludge was acclimatized to treatment with high loaded synthetic wastewater. Next, the optimal concentra

The possibility of using waste polystyrene to remove the hardness of water has been investigated. Waste of polystyrene is consisting of white coffee cups and they were converted into adsorbent by heterogeneous sulfonation. Infra red technique has been used to confirm the sulfonation. Degree of sulfo

One of the methods of achieving high selectivity or high flux for specific compounds is the modification of membrane such as filling, grafting or coating. The most common is adding fillers, especially high aspect ratio fillers. It improves physical properties such as increased stiffness or reduced c

Textile industries represent an important environmental problem due to their high water consumption. In many Spanish regions with water scarcity, this fact can be an argument to make wastewater reuse necessary. In this work, a biologically treated wastewater from a cotton thread factory was subjecte
