ABSTRACT:
The formation of hardness-caused deposits on the cathodic surfaces of cells used in the electrolytic production of hypochlorite from impure saline solutions is reduced and good current efficiencies are realized by employing flat, continuous cathodes having a surface roughness of less than 2.54 .times. 10.sup.-.sup.4 cm. and passing said solution by said cathodes during electrolysis at a velocity of from 0.3 meter/sec. to the number which is equal to the log expressed by the formula: Log velocity (in m/sec/3) = 1.0 - (available Cl.sub.2 concentration, in grams per liter, divided by 4).
