Abstract
Electropurification of contaminated aqueous media, such as ground water and wastewater from industrial manufacturing facilities like paper mills, food processing plants and textile mills, is readily purified, decolorized and sterilized by improved, more economic open configuration electrolysis cell designs, which may be divided or undivided, allowing connection as monopolar or bipolar cells. When coupled with very narrow capillary gap electrodes more economic operation particular when treating solutions of relatively low conductivity is assured. The novel cell design is also useful in the electrosynthesis of chemicals, such as hypochlorite bleaches and other oxygenated species.
