Title
(EN) On-line continuous monitor to optimize coagulant and floccul ent feed in wastewater and paint spray booth systems
Abstract
(EN)
An apparatus and method for optimizing coagulant and flocculent chemical feed in a wastefluid treatment system is disclosed which uses two or more contaminant-concentration dependent parametric detectors to measure the detected parameter in chemically-treated wastefluid and chemically-treated, solid-separated wastefluid.
