A sequential aerated electrocoagulation and peroxicoagulation process for the treatment of municipal stabilized landfill leachate by iron and graphite electrodes.

Electrochemical treatment has emerged as a viable technology for the treatment of leachate due to its efficient removal of ammonaical nitrogen and other recalcitrant organics. The main technical issues that prevent its practical deployment are restricted performance of a single electrochemical process and the lengthy tertiary treatment time required to achieve the disposal quality standards. This study demonstrates the performance of electrochemical treatments such as peroxicoagulation (PC) and aerated electrocoagulation (A-EC) separately and also sequentially for the treatment of stabilized leachate.

Chelate-modified Electro-Fenton process for mixed industrial wastewater treatment.

The Chelate-modified EF process for the removal of COD at near neutral pHTreatment of the mixed industrial wastewater with very low BOD/COD ratioInfluence of Fenton catalyst and chelating agent dosage on COD removal.Comparable COD removal of 67% with Chelate-modified EF at near neutral pH and 66% with EF at acidic pH.Mineralization current efficiency and instantaneous current efficiency for COD removal.

Electro-Fenton assisted sonication for removal of ammoniacal nitrogen and organic matter from dye intermediate industrial wastewater.

The intricacy in the treatment of effluents from the textile sector attracts the researchers since 20th century. Dye intermediate manufacturing industries are responsible for producing the toxic pollutants such as nitro-aromatics, benzene, toluene, phenol, heavy metals etc. with intense colour.

Mixed industrial wastewater treatment by combined electrochemical advanced oxidation and biological processes.

Nowadays, because the quality and quantity of mixed industrial wastewater keep fluctuating in recent times, the treatment of mixed industrial wastewater has gained more attention. The main target of this study is to degrade the wastewater through a combination of electrochemical advanced oxidation processes (EAOPs) and biological treatment. To enhance the biodegradability of the wastewater, Electro-Fenton process, along with external persulphate addition, was applied before the biological treatment.

Review of zero-valent aluminium based water and wastewater treatment methods.

Zero-valent metals (ZVM) are widely used to remove heavy metals, contaminants, toxicity, etc. from water and wastewater. Zero-valent aluminium (ZVAl) has large surface area and high surface reactivity.
