High rate mesophilic anaerobic contact reactors (MACR) represent a proven sustainable technology for a wide range of different industrial effluents. These reactors demonstrate quite similar features to their aerobic counterparts, activated sludge systems. A lab-scale high rate mesophilic anaerobic contact reactor was operated with wastewater originated from a potato-processing plant, at six different loading rates of 1.1-5g COD/L per day. The operational performance of MACR was monitored from start-up by assessing COD removal efficiency, total volatile fatty acid production and biogas composition. Furthermore, various kinetic models have been successfully applied to the experimental data to determine substrate balance, maximum utilization rate and volumetric methane production. The COD removal efficiencies were found to be 78-92% and the methane percentage of the biogas produced was 80-89%. Additionally, the methane yield coefficient was found to be 0.394 L CH(4)/gTCOD(rem).
高负荷中温厌氧接触反应器（MACR）是一种经过验证的可持续技术，可用于处理多种不同的工业废水。这些反应器与好氧对应物——活性污泥系统具有非常相似的特点。采用实验室规模的高负荷中温厌氧接触反应器，以每天 1.1-5gCOD/L 的六个不同负荷率处理来自马铃薯加工厂的废水。通过评估 COD 去除效率、总挥发性脂肪酸（TVFA）产量和沼气成分，从启动阶段开始监测 MACR 的运行性能。此外，还成功地将各种动力学模型应用于实验数据，以确定基质平衡、最大利用率和体积产甲烷率。COD 去除效率为 78-92%，产生的沼气中甲烷的百分比为 80-89%。此外，甲烷产率系数被发现为 0.394LCH4/gTCOD(rem)。
