Formazin turbidity unit
WebThe primary standard used to regulate turbidity is Formazin, which can match Jackson units to those of other methods used to measure low turbidity. The Formazin turbidity unit (FTU) and the nephelometer turbidity unit (NTU) can be converted to each other When Formazin is used to calibrate the nephelometer device. View chapter Purchase book WebTurbidity levels are measured in nephelometric turbidity units (NTU). According to the EPA, potable water must be kept at below 0.15 NTU for a stream coming out of an individual filtration line, and below 0.30 NTU for the combined filter …
