Wastewater generated in oil production and refinery industries contains high levels of pollutions. Water from the oil production field is the largest source of wastewater in the oil production and refinery industry. It can cause environmental problems on a global scale due to its high volume and...

This paper has studied phosphorus removal effects of ferric chloride (ionic state), polyferric chloride (polymer state) and ferric hydroxide (gel state) on the effluent of a municipal sewage treatment plant. The total phosphorus (TP) in the effluent was 1.74 mg·L-1. Results showed that ferric...

This paper aims to study a relative new technology, the online generation and application of ferrate(VI), for sewage treatment, from pilot to full scale trials at Hailsham North Wastewater Treatment Plant of Southern Water Ltd of UK. The work presented in this paper has significant impact on the use...

At present, chemical processes are widely used to remove phosphorus and organic matter from water or wastewater either as the only advanced treatment method or as a pre-treatment stage to biological treatment, and aluminium salts have been traditionally used as coagulants. In the present study...

The present study investigated tertiary physico-chemical treatment of the secondary effluent from the Chania municipal Wastewater Treatment Plant (WTP). Laboratory experiments were carried out with the aim of studying coagulation efficiency regarding reduction of turbidity, soluble COD and...
