Abstract
: This paper evaluates the washing interval of the rapid sand filter at the central drinking water treatment plant Nov á Ves—Fr ý dlant nad Ostravic í in the Czech Republic (DWTP Nov á Ves). The aim was to conduct automated flow cytometry measurements (FCM) and find the link between FCM and turbidity. The monitor parameters were the length of the wash cycle in hours, the flow rate of the filter and the production, the pumping of the recirculating wash water, and the physico-chemical and microbial analysis of the water samples. The focus of this paper is the detailed characteristics of the filtration mode evaluated during the summer and winter periods. During the measurements, it was confirmed that turbidity replicated the FCM data measured by the FC BactoSense instrument. Turbidity can be identified as one of the key features that can be related to the measurements made. Turbidity and the cell count itself are influenced, among other things, by the pumping of the return water, whereby an increase in the cell count can be observed after the pumping has stopped but gradually stabilizes at the values measured before pumping.
:本文评估了捷克共和国 Nov á Ves-Fr ý dlant nad Ostravic í 中央饮用水处理厂(DWTP Nov á Ves)快速砂滤器的清洗间隔。目的是进行自动流式细胞仪测量 (FCM),并找出 FCM 与浊度之间的联系。监测参数包括以小时为单位的洗涤周期长度、过滤器和生产的流速、循环洗涤水的泵送以及水样的物理化学和微生物分析。本文的重点是评估夏季和冬季期间过滤模式的详细特性。在测量过程中,浊度与 FC BactoSense 仪器测量的 FCM 数据一致。浊度是与测量结果相关的关键特征之一。浊度和细胞计数本身受回水抽水等因素的影响,在抽水停止后,可观察到细胞计数增加,但会逐渐稳定在抽水前的测量值。
