Crypsoporidium parvum 和 Giardia lamblia 是原生动物或单细胞寄生虫。这些寄生虫和孢子存在于世界每个地区,在地表水的直接影响下,它们可能成为来自湖泊、溪流和某些地下水源的大多数水中的污染物。污水处理设施可能由于产能过剩或处理不当而排放含有卵囊的污水。其次,农业活动或含有孢子的自然来源的径流可以进入地表水。
根据长期2强化地表水处理规则(LT2ESWTR-LT2),系统必须通过使用一种或多种处理方案来满足隐孢子虫的处理要求,处理要求由源水中的卵母细胞水平决定。隐孢子虫水平>0.075个卵母细胞/升需要隐孢子虫的总治疗量至少为4.0log,高达5.5log(>3个卵母细胞/升)。各州将根据美国环保局的要求批准用于证明性能的方法,并且必须批准系统组件和整个系统声称的日志信用。过滤器被允许作为整个处理过程的一部分,因此经过测试和认证,可以确定最低性能标准。

Wine lees, the sediment that accumulates at the bottom of the barrel during the winemaking process, are often overlooked in the journey from vine to glass. They are a complex mixture of organic compounds with a high oxygen demand (BOD). With values exceeding 30,000 mg/L, the disposal of wine lees poses a significant environmental threat. When managed improperly, these residues can lead to increased greenhouse gas emissions and oxygen depletion in water bodies, contributing to pollution and ecological imbalance.
