Abstract

Improved efficiency is obtained in the treatment of industrial waste waters, by irradiating photosensitive heavy metal salts with actinic light during the time the effluent is contacted with sequestering natural polymers. Coagulation and adsorption occur concurrently.

Actinic Treatment of Industrial Wastes

Improved efficiency is obtained in the treatment of industrial waste waters, by irradiating photosensitive heavy metal salts with actinic light during the time the effluent is contacted with sequestering natural polymers. Coagulation and adsorption occur concurrently.

Zein and casein, in particular, exhibit enhanced sequestering capability for cupric ions when used in conjunction with a commercial ultraviolet light source.

In addition, concurrent actinic radiation is helpful in shortening chemical reduction and reaction times in the more complex treatment processes, for example, in the chlorination of cyanide and conversion of chromates to their salts.
