The pulp and paper industry is one of the economic backbones of Canada. However, waste management has been a significant challenge for this industry. It was estimated that Canadian pulp and paper mills produced about 1.7 million metric tons (dried) sludge (in 2005) that need further treatment and disposal. The current practice of pulp and paper mill sludge management includes the use of mill sludge as low heat value biofuel after dewatering and drying (which is an energy intensive process) or as landfill or inland reclamation. However, incineration of mill sludge is considered as poor quality biofuel, due to the high water content. Furthermore, landfill of mill sludge or the use of mill sludge in inland reclamation projects faces the challenges of increased cost and environment concerns. Therefore, finding a low cost, environmentally sustainable, long-term solution to handling pulp and paper mill sludge is of critical importance to the industry. The proposed research program will focus on the development of an innovative anaerobic membrane bioreactor (AnMBR) technology for bioenergy recovery from mill sludge in wet form. It is anticipated that the proposed research program will develop compact, high efficient membrane technologies for bioenergy production with efficiencies that are not achievable with current technologies. Furthermore, improved fundamental understanding of membrane fouling mechanisms and fouling control will be developed to improve the efficiency of the AnMBR systems. The success of the proposed study will solve the sludge management problems of the pulp and paper industry and enhance the leading role of Canada in wastewater technologies.

纸浆和造纸业是加拿大的经济主持人之一。但是，废物管理一直是该行业的重大挑战。据估计，加拿大纸浆和造纸厂生产了约170万吨污泥（2005年），需要进一步的治疗和处置。当前的纸浆和造纸厂污泥管理的做法包括在脱水和干燥后（这是一个能源密集型过程）或垃圾填埋场或内陆开垦后将磨坊污泥用作低热量的生物燃料。但是，由于水含量较高，磨坊污泥的焚化被认为是质量差的生物燃料。此外，磨坊污泥或在内陆开垦项目中使用磨坊污泥面临成本和环境问题的挑战。因此，寻找低成本，环境可持续的长期解决方案来处理纸浆和造纸厂污泥对行业至关重要。拟议的研究计划将着重于开发创新的厌氧膜生物反应器（ANMBR）技术，以从湿污泥中以潮湿形式从磨坊污泥中恢复生物能源。预计拟议的研究计划将开发紧凑，高效的膜技术，用于生物能源生产，并具有目前技术无法实现的效率。此外，将开发对膜结垢机制和结垢控制的基本了解，以提高ANMBR系统的效率。拟议的研究的成功将解决纸浆和造纸行业的污泥管理问题，并增强加拿大在废水技术中的主要作用。
