Key Features

A review of electrochemical reactor systems for the recovery of metals and for pollution control applications is presented. The major engineering factors which influence the design of reactors are evaluated and the key features of two-dimensional and three-dimensional reactor designs are discussed. Some examples of the application of electrochemical reactors to the recovery of metals from dilute solutions are given in the form of case studies, covering both pollution control and resource recovery processes. Finally a comparison is made of the relative technical and economic merits of electrochemical recovery pollution control systems and conventional chemical waste treatment routes.

Electrochemical Incineration

This work shows results obtained in the electrochemical incineration of a synthetic vinasse with initial chemical oxygen demand (COD) of 75.096 g L−1 in aqueous media (which resembles vinasse industrial wastewater). Electrolyses in a filter-press-type FM01-LC electrochemical reactor equipped with a three-dimensional (3D) boron doped diamond electrode (BDD) were performed at Reynolds values between 22 ≤ Re ≤ 109, and a fixed current density of 10 mA cm−2. The electrochemical incineration achieved up to 97% in vinasse mineralization with current efficiencies that surpass unity and energy consumption of 168 KW-h m−3, at Re =109. The mineralization of vinasse indicates that such degradation occurs via hydroxyl radicals formed by the oxidation of water on the BDD surface. Experimental data revealed that hydrodynamic conditions slightly influence the vinasse degradation rate and current efficiency, indicating that the oxidation involves a complex pathway.

Electrochemical processes are the most adequate tools in the aqueous effluent treatment. The process will not require chemical addition and indeed electrons are the only reactants added to the process to stimulate the reaction. Anodic oxidation of recalcitrant wastewater in a typical electrochemical set-up is particularly interesting because of its ease of operation and scope for scale-up. Nevertheless, electro oxidation in the three-dimensional carbon bed electrodes is a promising process for electrooxidation of effluents containing non-biodegradable organic compounds. The application of three-dimensional carbon bed electrochemical reactor for the degradation of organic pollutant is demonstrated in this chapter. The role of carbon particles in the three-dimensional electrodes reactor is described in this chapter. It has at least two important functions: 1) adsorption of organic compounds from effluents and 2) act as particle electrode. Various operation and design considerations leading to better understanding of carbon bed electrochemical reactors are discussed.
