采用生物电化学法从制革废水中回收铜。6.8 L总体积。两种控制策略的基础上的控制与最大功率点跟踪（MPPT）和0.5 V的应用程序使用外部电源的功率被用来调查所得的改性电镀特性。反应器系统由两个电气分离但液压连接的电池构成，并应用MPPT和0.5 V控制策略。使用相对较高的铜浓度（即1000 mg/L），然后使用较低的浓度（即50 mg/L），进行了三个实验，定义了操作运行时间，以满足所考虑的制药厂废水的处理要求。将真实的冶金废物引入阴极中以降低离子铜浓度。然后将该废物在铜耗尽步骤之后作为原料再循环到阳极，以测试系统的生物能自维持性。约取决于起始浓度，60-95%的铜以沉积物的形式回收。然而，当阳极供应有贫铜的冶炼废物时，回收率低。通过过程控制（MPPT或0.5V施加电压），可以操纵回收的铜的量和形式。
Copper recovery from distillery effluent was studied in a scalable bioelectro-chemical system with approx. 6.8 L total volume. Two control strategies based on the control of power with maximum power point tracking (MPPT) and the application of 0.5 V using an external power supply were used to investigate the resultant modified electroplating characteristics. The reactor system was constructed from two electrically separated, but hydraulically connected cells, to which the MPPT and 0.5 V control strategies were applied. Three experiments were carried out using a relatively high copper concentration i.e. 1000 mg/L followed by a lower concentration i.e. 50 mg/L, with operational run times defined to meet the treatment requirements for distillery effluents considered. Real distillery waste was introduced into the cathode to reduce ionic copper concentrations. This waste was then recirculated to the anode as a feed stock after the copper depletion step, in order to test the bioenergy self-sustainability of the system. Approx. 60–95% copper was recovered in the form of deposits depending on starting concentration. However, the recovery was low when the anode was supplied with copper depleted distillery waste. Through process control (MPPT or 0.5 V applied voltage) the amount and form of the copper recovered could be manipulated.
