Abstract

AbstractIn‐situ production of sodium hypochlorite is one of the oldest electrochemical processes of the chemical industry. During the past twenty years a new “in‐situ” hypochlorite industry has developed. Construction and performance of present‐day cells are considered in detail. Modern cells are fed with seawater or similar weak brines and yield solutions suitable for disinfection, e. g. in breweries, laundries, etc., or for treatment of municipal sewage. Particular importance attaches to units for chlorination of cooling water for power stations or on board ships, thus hindering growth of organisms leading to operating failures. The article closes by considering development trends.
