已经进行了中试规模的实验，以评估常规治疗在稳态条件下控制隐孢子虫卵囊的能力。这项工作是在一个中试装置上进行的，该装置旨在最大限度地减少流量和连续加料所需的卵囊数量。将活卵囊以106/L的浓度注入植物进水中36至60小时。通过沉淀和过滤测定卵囊去除率和替代参数浊度、总颗粒数和需氧内孢子。卵囊对数去除率与凝血和沉淀过程中的所有替代参数呈正相关。 在适当的混凝控制下，常规处理工艺达到了临时强化地表水处理规则（IESWTR）授予的隐孢子虫去除总量2对数的信用。在所有未达到2对数总去除率的情况下，工厂也不符合IESWTR的过滤废水浊度要求。

Pilot-scale experiments have been performed to assess the ability of conventional treatment to control Cryptosporidium oocysts under steady-state conditions. The work was performed with a pilot plant that was designed to minimize flow rates and the number of oocysts required for continuous spiking. Viable oocysts were fed into the plant influent at a concentration of 106/L for 36 to 60 hours. The removals of oocysts and the surrogate parameters turbidity, total particle counts, and aerobic endospores were measured through sedimentation and filtration. There was a positive correlation between the log removals of oocysts and all surrogate parameters through the coagulation and settling process. With proper coagulation control, the conventional treatment process achieved the 2 log total Cryptosporidium removal credit granted by the Interim Enhanced Surface Water Treatment Rule (IESWTR). In all cases where 2 log total removal was not achieved, the plant also did not comply with the IESWTR's filter effluent turbidity requirements.
