Odorous compounds have long been a significant problem faced by mills treating their own wastewater. This problem can be compounded when mechanical dewatering equipment is used to process primary and secondary sludges.
Plainwell Paper Company, a competitive producer of fine printing and technical specialty papers, is no exception to this rule. Along with the start-up of their new waste water treatment facility, which includes an Arus-Andritz sludge dewatering machine, came an irritating and potentially harmful odor problem. It was determined that the major cause of the odor was hydrogen sulfide.
