Innovations in the washing sector and the continued advancement of our pioneering wet processing solutions are supporting quarry operators and materials processors alike to overcome the challenges stemming from water management; cost-based, efficiency, sustainability, and regulatory.
Analysis of SCM processed water quality. Wastewater was collected in plastic jars from SCM area and physicochemical analysis such as pH, total dissolved solids (TDS), dissolved oxygen (DO), BOD, COD, Ca, Mg, Cr(VI), SO 4 2−, Fe before and after the phytoremediation was performed.The value at zero (0) day was noted as initial value while the value recorded after …
Commercial EO and ER operations using diamond electrodes are still limited to niche applications on a relatively small scale. The versatility and tunability of EO and ER provide tailored solutions to specific wastewater treatment needs, such as the on-site removal of non-biodegradable toxic compounds in industrial wastewaters, or systems with small space …
Reuse tailings pond water and other wastewater. Managing the mining wastewater in a tailings pond requires more than just pumps. Xylem customizes processes that provide nonpotable reuse water for further treatment using Xylem-engineered UV treatment, ozone wastewater treatment, or biological treatment systems. Conserve resources with ozone ...

Boron-doped diamond (BDD) thin film electrodes have great application potential in water treatment. However, the high electrode energy consumption due to high resistance directly limits the application range of existing BDD electrodes. In this paper, the BDD/graphene/BDD (DGD) sandwich structure electrode was prepared, which effectively …
2.2. Experimental design and procedure. The experimental procedure was carried out in a batch reactor with two aluminum (Al(−)/Al(+)) or two iron (Fe(−)/Fe(+)) electrodes (anode and cathode with 12 cm 2 area) under magnetic stirring (Fig. 1 S).The distance between anode and cathode was the least possible (3 mm), since decreasing the gap between the two …
