A bipolar electrolyzer is provided which includes a plurality of bipolar electrode sub-assemblies which position the electrodes in the cells in a manner such that improved electrical operating characteristics are achieved. Each bipolar electrode sub-assembly includes an alternating stack of electrically insulating spacer members and bipolar electrodes. Electrodes are horizontally received in a channel in the electrically insulating spacer members which fixes the spaced relationship between juxtapositioned anodes and cathodes.

Disclosed is a new form of brine flow meter necessary in metering brine to an electrolytic cell for the production of chlorine and caustic (sodium hydroxide). The flow meter is made advantageously of a plastic material resistant to the various pH ranges necessary for brine being fed to such an electrolytic cell with the additional advantage of clarity for visual observation of the flow rate and resistance qualities.

Disclosed is a cyclone for use in conjunction with electrolytic cells for separating a gas such as hydrogen from the electrolyte solution so as to significantly increase the efficiency of subsequent cells connected in series in a large bank of electrolytic cells. The subject cyclone is especially useful in a sea water hypochlorite electrolytic cell wherein the flow rate of electrolyte is in the range of 20 to 80 gallons per minute (75 to 300 liters per minute).
