While odor associated with reduced sulfur compound emissions from pulping processes is well-understood, managing odor in wastewater, from wastewater treatment systems, and from other sources is considerably more challenging. NCASI has developed numerous resources and tools to assist mills in identifying sources of odor, the offending substances, and strategies for mitigating releases of odors that are sometimes associated with mill operations.
NCASI developed H2SSIM to model sulfide fate and transport in wastewater treatment basins. H2SSIM provides hydrogen sulfide emissions estimates from wastewater treatment basins used by the forest products industry.
