Effective pulping liquor management and spill prevention and control systems at kraft and sulfite mills will become increasingly important as mill operation attempt to achieve minimum effluent and to comply with Best Management Practices (BMP) regulations currently being considered by the U.S Environmental Protection Agency (EPA). We present the results of an extensive review of kraft and sulfite pulping liquor management and spill prevention and control systems conducted to support development of EPA’s proposed BMP regulation, and an analysis of the status of the industry with respect to implementation of effective systems. Those management systems and operating practices (non-hardware) and spill collection and recovery systems (hardware) found to be most effective am reviewed. Estimated costs to install such systems are and and a case study is presented to demonstrate economic and effluent reduction benefits attainable.
