A comparison of ultrafiltration on various river waters

摘要: Hollow fiber ultrafiltration is used to remove virus, Giardia, Cryptosporidium, and coliform reduce turbidity TOC from surface waters produce potable water. The application of technology the municipal water market an extension its success in a myriad applications. membranes can consistent filtered inconsistent feed sources without use pretreatment. Data will be discussed four US river having various qualities: Boise River (Idaho), Medina (Texas), Cumberland (Tennessee), Wishkah (State Washington). Polysulfone are highly chemically resistant provide positive barrier, preventing passage microorganisms skinned construction hollow membrane provides physical barrier which removes contaminants separates them treated stream. Long life ensured by mechanical cleaning techniques, low pressure backflush, flow reversal.
