Anaerobic digestion (AD) is a well established technology to convert biomass to energy and reduce the**environmental impacts of organic wastes such as organic fraction of municipal solid waste, sewage sludge or dairy waste. However, the AD process is susceptible to influence of toxicity due to high ammonia concentrations.**Ammonia is the by-product resulting from the AD of proteins content of organic matter and it has been reported**as a major inhibitor of microbial activities during AD process. A wide range and varying effect for ammonia**toxicity has been reported in the literature. Also, there is very limited information available on removal of ammonia from digestate of Co-Digestion process of mixed feedstock. **CHFour Biogas is a Canadian company and an industry leader in the field of AD. CHFour Biogas specializes in the**design, installation and optimization of anaerobic digestion systems for the agricultural, industrial and municipal**sectors throughout North and South America offering a comprehensive list of services including feasibility study**and analysis, biogas system design & specification, consultations and construction management, feed stock**evaluation & system modeling, permitting, approvals, and regulations. CH Four Biogas is interested in conducting research on the feasibility of enhancing the performance of anaerobic Co-Digestion (A-CoD) of mixed feedstock organics (including livestock manure, digestible manufacturing waste, pre- and post-consumer food wastes) by removal of ammonia. **The research will be carried out by conducting a series of laboratory biomethane potential (BMP) experiments according to a full factorial experimental design to evaluate the feasibility of different methods for removal of ammonia and its effect on biogas production from A-CoD of mixed organic feedstock wastes. Results will advance the existing knowledge on the design and operation of AD process.

厌氧消化 (AD) 是一项成熟的技术，可将生物质转化为能源并减少有机废物（例如城市固体废物、污水污泥或乳品废物的有机部分）对环境的影响。然而，由于高氨浓度，AD 过程容易受到毒性的影响。**氨是有机物中蛋白质含量 AD 产生的副产品，据报道**是 AD 过程中微生物活动的主要抑制剂。广告过程。文献报道了氨**毒性的广泛且不同的影响。此外，关于从混合原料的共消化工艺的消化液中去除氨的信息非常有限。 **CHFour Biogas 是一家加拿大公司，是 AD 领域的行业领导者。 CHFour Biogas 专门为北美和南美的农业、工业和市政行业**设计、安装和优化厌氧消化系统，提供全面的服务，包括可行性研究**和分析、沼气系统设计和规范、咨询和施工管理、原料**评估和系统建模、许可、批准和法规。 CH Four Biogas 有兴趣开展研究，通过去除混合原料有机物（包括牲畜粪便、可消化的制造废物、消费前和消费后食品废物）来提高混合原料有机物厌氧共消化 (A-CoD) 性能的可行性。氨。 **该研究将根据全析因实验设计进行一系列实验室生物甲烷潜力（BMP）实验，以评估不同方法去除氨的可行性及其对混合沼气中A-CoD产生沼气的影响。有机原料废物。结果将推进 AD 过程设计和操作的现有知识。
