Abstract
Abstract A water treatment system having a scanner circuit which monitors and controls and takes corrective action upon receiving signals from pH-sensing apparatus, conductivity-sensing apparatus, or corrosion rate sensing apparatus, singly or together, and provides electrical timing means for stopping or starting acid or alkaline feed equipment, bleed valves in the system, and various pump means for adding chemicals to the system.
