ABSTRACT:
Disclosed is a bipolar electrolyzer having a plurality of individual electrolytic cells electrically and mechanically in series. Each of the cells has an anolyte chamber, a catholyte chamber, and catholyte liquor withdrawal means. A catholyte liquor trough is disposed along side the electrolyzer and beneath the catholyte liquor withdrawal means. The bipolar electrolyzer is characterized by apparatus for limiting the emission of catholyte liquor laden moisture from the cell liquor trough while simultaneously being capable of indicating a low catholyte liquor level in an individual electrolytic cell of the electrolyzer. Additionally, the apparatus may interrupt the flow of catholyte liquor between the catholyte chambers of the individual electrolytic cells and the catholyte liquor trough, thereby reducing corrosion of the perc pipes. The emission limiting means and low catholyte liquor level indicating means include a top on the cell liquor trough. The top of the cell liquor trough has recesses corresponding to the individual catholyte liquor withdrawal means. The recesses have apertures which communicate with the cell liquor trough at the intended level of cell liquor in the recess and second apertures communicating with the cell liquor trough below the first apertures.
