Chemelec cell — An electrolytic cell with electrodes (both anode and cathode) made from expanded metal or simple metal plates. The cell is filled with inert particles, which are floated when the electrolyte solution enters the cell from the bottom. This causes effectively turbulence with increased - mass transport. This cell is employed in wastewater treatment especially from galvanic operations.

Cells with relatively small electrode area but improved mass transport to increase km by setting the electrodes in motion or by applying turbulence promoters. Examples are the pump cell [55, 56], the Chemelec cell [57], the ECO cell [58-60], the beat-rod cell [61, 62], and cells with vibrating electrodes or electrolytes [63]. 

Chemelec cell with fluidized-bed glass beads within electrodes. The cell performance is achieved mainly by electrolyte movement. The cathode product is removed by scraping or used as anodes. 

Two-dimensional electrodes. Two-dimensional electrodes appropriate for metal recycling are typically based on the tank electrolyser to enable ready removal of metal plated electrodes. The simplest cells are the vertical, plate or mesh, electrode in tank units where turbulence is provided by using either inert fluidised beds [8] (Chemelec Cell, BEWT Water Engineers Ltd.) or air agitation (Reconwin cell), in conjunction with electrolyte pumping (see Figure 11.3).

Another practical approach is to promote electrolyte turbulence via the use of an expanded-mesh electrode in a solution containing fluidized inert particles (typically 1 mm glass ballotini). This is the principle of the Chemelec cell (Fig. 7.4) which has been widely applied to metal finishing, photographic silver-recovery and precious metal reclamation processes.
