Instrumentation and control modules for the optimization of water chemical treatment process

Summary

The results of introducing instrumentation and control modules of «Coagulant–clarifier», automatic coagulant dosing and «Chlorine–monitoring» are presented. The modules were designed for measuring turbidity, coagulated suspension clarification rate, coagulant dosage, and free residual chlorine in 33 water samples taken from different points of the chemical treatment process at pumping-filtration plant No. 1 of Novosibirsk. The modules were incorporated into UNITOK-DISPETCHER integrated automated software control and management system. The use of flow receiving and distribution units and a set of flow-type sensors provides for fulfilling the task of automated control of the entire process flows. The stabilization of process parameters is achieved by automation of dosing coagulant process solutions in the mixing chambers of the first and second plant blocks. Ten-year experience of operating the modules showed that the reliability and operational efficiency of the instrumentation systems, objectiveness (laboratory independence), free choice of sampling number and rate improve the operational efficiency of decision making by the control service, process techno­logy optimization, and ensure reliable high-quality drinking water supply.
