Alum - an overview | ScienceDirect Topics
This method can be used with polyaluminum chlorides (PACs), but low aluminum values may be obtained as the polymer forms of aluminum may react slowly. Perhaps a method could be developed where excess fluoride is added (if the approximate
An OG value of 0.050 mg/L (50 μg/L) is proposed for total aluminum to optimize water treatment and distribution systems. This document is available for a 60-day public consultation period. Please send comments (with rationale, where required) to
