Control of \tVater Pollution froIll the Discharge of Liquid Effluents of \tV et-Collector Type Gas-Cleaning SysteIlls

Wet-collector systems, designed and operated for air-pollution control without concern for or con­ sideration of the stream-pollution effects of their liquid-borne wastes, may cause significant localized pollution of surface and ground water bodies. Wet­ collector systems can be designed with presently known technology to decrease contaminants in effluent outfalls to acceptable levels. Increasing strictness and complexity of air-pollution regulations will result in growing diversification in the use of ver­ satile wet-collector systems. Judicious selection of wet-collector type, and advantageous use of design in­ novations in the scrubbing liquid circuitry, will ensure the most economical overall gas-cleaning system design that meets the objectives of both air and water pollution -control regulations.
