Wastewater Treatment System Performance

NCASI provides technical information that members rely upon to maintain or enhance the performance of wastewater treatment systems. Recently, members have indicated a growing interest in modern monitoring approaches and alternative means for characterizing system health and on-going effectiveness. These novel methods of monitoring and predicting performance may help members in recognizing, diagnosing and resolving upset conditions and responding effectively to circumstances such as changes in mill loads, wastewater characteristics, and effluent quality targets.

Topics

Dredging

Companies managing aerated stabilization basins (ASBs) can be challenged by the accumulation of sediments within the basin.  Such accumulation can reduce the residence time of water begin treated in the basin, alter the intended flow pattern of the wastewater within the basin, and result in feedback from degrading biomass that…

Managing Aerated Stabilization Basins (ASBs)

Use of aerated stabilization basins (ASBs) for treating wastewater is a very common practice in the forest products industry.  Basins used for this purpose are unique in many ways and, as such, operational techniques and long-term management strategies for these systems are not widely known outside the industry.

Nutrients

Nutrients and nutrient-related pollution are a leading cause of impairments to US waters, and environmental agencies are very actively engaged in designing management programs to address these impairments.

Odor

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.
