Purification of wastewater by electrolysis

Purification of Floodwater by Electrolysis

An adequate supply of pure water is absolutely essential to human existence. During floods, water is available in adequate quantity, but the quality is often not suitable for drinking or cooking purposes. The goal of the study was to develop an easier, cheaper and faster technique of water purification. Oxygen ions are well known for their high reactivity. An attempt has been made to use oxygen...

Electrochemical disinfection of toilet wastewater using wastewater electrolysis cell.

The paucity of proper sanitation facilities has contributed to the spread of waterborne diseases in many developing countries. The primary goal of this study was to demonstrate the feasibility of using a wastewater electrolysis cell (WEC) for toilet wastewater disinfection. The treated wastewater was designed to reuse for toilet flushing and agricultural irrigation. Laboratory-scale electrochem...

Removal of mercury from chloralkali electrolysis wastewater by a mercury-resistant Pseudomonas putida strain.

A mercury-resistant bacterial strain which is able to reduce ionic mercury to metallic mercury was used to remediate in laboratory columns mercury-containing wastewater produced during electrolytic production of chlorine. Factory effluents from several chloralkali plants in Europe were analyzed, and these effluents contained total mercury concentrations between 1.6 and 7.6 mg/liter and high chl...

Using Taguchi Method to Optimize Recovery of Bismuth by Electrolysis

This paper presents a methodology, based on the taguchi parameter design approach, for the optimization of process parameters for bismuth recovery from aqueous solutions. The process parameters considered are [Bi3+], [NaCl], temperature, and cathodic current density. In addition, cell voltage and current efficiency as two responses have been considered. An orthogonal array L9, the signal-to-noi...
