What is the Use of Ground Beds in Cathodic Protection? The cathodic protection type determines how the cathodic current is supplied to the structure. Cathodic protection can be applied by either an impressed current system or by a sacrificial anode system. Impressed current cathodic protection systems use an external DC current source and a variety of anode materials to supply the cathodic current. Sacrificial anode CP systems generate the cathodic current from the corrosion of metals less noble than the metal to be protected.

What is The Application of Dimensionally Stable Anode (DSA) in Wastewater Treatment?  Coated titanium electrode is also named DSA (dimensionally stable anode). This electrode is the main form of metallic oxide. The distance between anode and cathode will not change, so its electrode wear is small and the size is stable. This dimensionally stable anode has been widely used in the electrolysis industry because of its property, which brings lots of advantages. DSA is a type of electro-catalytic electrode, which

What Are the Advantages of Dimensionally Stable Anodes Compared with Graphite Anodes? Electro-catalyst enables the electron transfer reactions at the electrode-electrolyte interface with substantial energy savings. The total energy consumption in the chloro-alkali process is proportional to the total cell voltage, including the thermodynamic potential of anodic and cathodic reactions, electrode over potential, and an ohmic drop from the electrolyte, membrane, and bubble effect, etc.   The electrode upon which oxidation occu

The Problems of Lead Anodes in Copper Electrowinning Historically, lead anodes are used in copper electrowinning due to lead's abundance, good conductivity, corrosion resistance, and relatively low cost. The corrosion resistance of these anodes is a product of the formation of PbO2 via PbSO4 under oxidative conditions during electrowinning. This passivation layer is attributed to the added benefit of self-regeneration in the event of a short circuit between electrodes. Pb-Ca-Sn and Pb-Sr-Sn anodes were developed to replace P
