Discharge diaphragms

Chloiine is pioduced at the anode in each of the three types of electrolytic cells. The cathodic reaction in diaphragm and membrane cells is the electrolysis of water to generate as indicated, whereas the cathodic reaction in mercury cells is the discharge of sodium ion, Na, to form dilute sodium amalgam. 

The OMD leaf filter (Stella Meta Filters) is a vertical leaf filter with a mbber diaphragm suspended between the leaves. The cake that forms on the leaves eventually reaches the diaphragm at which point pump pressure is used to inflate the diaphragm and compress the cake. The cake discharge is by vibration.

Panel fans A simple form of axial fan with its impeller mounted in a ring or diaphragm it discharges air both axially and radially. 

This is really a simple form of axial fan but with its impeller mounted in a ring or diaphragm which permits it to discharge air with both axial and radial components. Duties covered are high volume and low pressure. Static efficiency is normally under 40 per cent.

Diaphragm discharge is a liquid phase discharge at ambient temperature and atmospheric pressure [9], The reactor configuration, as shown in Fig. 1 [10], consists of Pyrex tube and a pair of electrodes set in the liquid fuel. The insulated teflon-membrane (diaphragm membrane), with its single pinhole, is placed in the gap of electrodes.

Finally, nickel is electrolytically produced from the purified nickel-bearing solution. In electrowinning of nickel, the hydrogen discharge reaction competes with nickel deposition at the cathode. This counterproductive effect is minimized by keeping the acidic anolyte solution separate from the catholyte by means of a diaphragm cloth.
