The Disposal of Textile Wastes with Domestic Sewage
1941
Horton, Robert K. | Baity, Herman G.
Disposal of textile wastes with domestic sewage appears log ical since it reduces the capital outlay for plant facilities, places all treatment under constant and skilled supervision, and elimi nates many chances of neglect and mismanagement by mill labor. Of the many problems arising from combined treatment the most important is the character of sewage reaching the disposal plant. Equalization and regulation of discharge of industrial wastes are necessary to prevent rapid change in environmental conditions for the bacteria and other organisms carrying on purification proc esses. Reduction of waste volume and recovery of by-products should be employed wherever practical. Preliminary treatment, including nentralization, chemical precipitation, and aeration is sometimes necessary to lessen the load applied to biological proc esses. The activated sludge process and biological filters employing recirculation of the effluent can be used successfully to treat textile wastes-domestic sewage mixtures. The activated sludge process removes color better, but it is more easily upset by variations in the character of the waste. In general, digester capacity will have to be increased when treating textile wastes with domestic sewage. The successful treatment of textile wastes in conjunction with domestic sewage calls upon the operator for the highest type of service. By means of adequate control and adjustment of the various, processes excellent results are obtainable.
