This method relies on in situ formation of hydroxide ions by electro mediated water reduction at a titanium ,cathode, surface. The in situ raised pH at the ,cathode, provides a local environment where CaP will become highly supersaturated. Therefore, homogeneous and heterogeneous nucleation of CaP occurs near and at the ,cathode, surface.

These, copper, species can migrate towards, the, negatively charged, cathode,, as observed for, the, oxides, and, residual fractions, of the, freshly amended sludges (Fig. 3a). Besides electromigration, also electro-osmotic, water, flow can contribute to an increased, copper, content at, the cathode, side.

According to Wu et al. , the, copper, covered on the carbon cloth of the, cathode, would decrease the subsequent, Cu, 2+ reduction rate. After 48 h of treatment, almost all the, Cu, 2+ (99.95 ± 0.09%) in simulated AMD were selectively recovered by MFC, with a low concentration of, Cu, 2+ (0.15 mg/L) remaining in, catholyte,, which meets the standard of China (GB25467-2010).

Fossil fuel power station - Wikipedia

A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity.Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator.The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine.

The protons are conducted through the membrane to the ,cathode,, but the electrons are forced to travel in an external circuit (supplying power) because the membrane is electrically insulating. On the ,cathode, catalyst, oxygen molecules react with the electrons (which have traveled through the external circuit) and protons to form water.
