Removal of Organic Solvents from Wastewater by Ozonization, Active Carbon Adsorption and Chemical Precipitation with Calcium Polysulfide

Optimization of organic compounds removal from Wastewater by Electrocoagulation

Introduction: As the most hazardous sewage, hospital wastewater contains various contaminants, and its uncontrolled discharge can seriously damage the environment. Bandar Abbas is located in an arid and semi-arid region therefore, hospital wastewater should be treated through an appropriate and economic method. This study aimed to determine the efficiency of electrocoagulation with aluminum and...

Physico-chemical Processes for Organic Removal from Wastewater Effluent

Phenol Removal from Aqueous Solutions by Adsorption on Activated Carbon of Miswak’s Root Treated with KMnO4

Background and Purpose: Phenol and derivatives are common pollutants of drinking water which are blamed for crucial adverse effects such as poisoning, cancer, and malformation. In this study, an activated carbon of Miswak’s root (MR) was used for the removal of phenol from aqueous solutions as a low-cost and high surface adsorbent. Materials and Methods: Adsorption exper...

Removal of residual phenols from coke wastewater by adsorption.

After biological treatment, coke wastewater contains small amounts of phenolic compounds resistant to such treatment. The removal of phenols and COD from coke wastewater subjected to biological treatment was studied. The adsorbents used were granular activated carbon and the resins XAD-2, AP-246 and OC-1074. Equilibrium, kinetics and column assays were carried out, fitting the equilibrium data ...

Removal of chromium (VI) from aqueous solution by adsorption using cousinia eryngioides boiss and activated carbon

Adsorption capacity of Cr (VI) onto cousinia eryngioides boiss, activated carbon was investigated in a batch system by considering the effects of various parameters like contact time, initial concentration, pH, temperature, agitation speed, absorbent dose and particle size. Cr (VI) removal is pH dependent and found to be maximum at pH 2.0. The amounts of Cr (VI) adsorbed increased with increase...
