本研究考察了卵囊保存方法和年龄对去除种子隐孢子虫的影响 卵囊通过在线过滤。现有的一项研究调查了微小隐孢子虫作为一种病原体的传染性 保存方法和卵囊年龄的作用。然而，类似的研究尚未进行调查 保存方法和卵囊年龄对隐孢子虫物理去除的影响。以前的试点规模 种子研究使用了在受控条件下储存的新鲜卵囊。然而，全面饮酒 水处理厂每天都会遇到不同年龄的卵囊。年龄和性别的差异 环境可能会通过水处理影响隐孢子虫的去除效率。因此，来自 这项研究可能有助于饮用水企业更好地评估和应用其他公布的数据。 在目前的研究中，同一生产批次的卵囊被分割并使用不同的方法保存。 在2、8和17周龄时，将每种保存方法的卵囊接种到中试规模的在线过滤器中。 随着年龄或保存时间的延长，清除率无统计学显著差异（95%置信水平） 观察方法。根据保存方法和保存时间，观察到的隐孢子虫平均数量 清除量为3.5至4.0 log。包括15个参考文献、表格和图表。

This study examined the impacts of oocyst preservation method and age on the removal of seeded Cryptosporidium oocysts by in-line filtration. An existing study has investigated the infectivity of Cryptosporidium parvum as a function of preservation method and oocyst age. However, similar studies have not been performed to investigate the impacts of preservation method and oocyst age on the physical removal of Cryptosporidium. Previous pilot scale seeding studies have used fresh oocysts stored under controlled conditions. However, full-scale drinking water treatment plants encounter oocysts of widely different ages on a daily basis. Differences in age and environment may affect Cryptosporidium removal efficiency through water treatment. As a result, the data from this study may help drinking water utilities better evaluate and apply other published data to their situation. In the current study, oocysts from the same production lot were divided and preserved using different methods. Oocysts from each preservation method were then seeded into pilot-scale in-line filters at 2, 8 and 17 weeks of age. No statistically significant (95% confidence level) differences in removals as a function of age or preservation method were observed. Depending on the preservation method and age, observed average Cryptosporidium removals ranged from 3.5 to 4.0 log. Includes 15 references, tables, figures.
