Chemical characteristics and microbiological quality of filtered water generated from municipal water using mono-, di- and penta-stage (5-stage) filters, as well as disposed drain water were investigated. With the application of the household water penta filters, the total dissolved solids (TDS) of the filtered water were highly reduced (0.04–0.07 g/L) and, consequently, electrical conductivity also decreased. Furthermore, total hardness was completely removed (0–2 mg CaCO3/L), as well as the chloride content. In the same manner, the nitrate content in the filtered water resulted from the household water penta filters decreased significantly (0.5–0.9 mg/L). Cations, such as Na+ and K+, in the filtered water were greatly affected and were 18–28 and 2 mg/L, respectively. Filtered water generated from the house-water penta filters was not in compliance with the daily amounts of F, Na and K necessary for teenagers and kids, and it might cause a risk of deficiencies. From the microbiological point of view, the penta-stage filter effectively removed total bacterial counts and total coliforms from water making it completely safe for potable and other domestic uses. The home water mono- and di- filters had low effectiveness of contaminant removal.

Поведено исследование химических характеристик и микробиологических показателей фильтрованной воды, полученной из муниципальной воды с использованием одно-, двухи пяти-стадийных фильтров, а также удаляемой сточной воды. При применении домашних пяти-стадийных фильтров, общее количество растворённых в воде веществ (TDS) в фильтрованной воде было существенно снижено (0,04–0,07 г/л) и, следовательно, также была снижена электропроводность. Кроме того, общая жесткость была полностью удалена (0–2 мг CaCO3/л), также как и содержание хлоридов. Аналогичным образом, содержание нитратов в фильтрованной воде, полученной от домашних пяти-стадийных фильтров воды, значительно уменьшилось (0,5–0,9 мг/л). Большое влияние было оказано на катионы в фильтрованной воде, такие как Na+ и K+, которые были на уровне 18–28 и 2 мг/л, соответственно. Фильтрованная вода, полученная от домашних пяти-стадийных фильтров воды, не соответствовала суточным количествам F, Na и K, необходимым подросткам и детям, что может представлять риск дефицита. С микробиологической точки зрения домашние пяти-стадийные фильтры воды эффективно удаляли общие количества бактерий и общие колиформы из воды, что делало её полностью безопасной для питья и другого домашнего использования. Домашние однои двухстадийные фильтры воды имели низкую эффективность удаления контаминантов.
