Abstract:
A method for controlling the concentration of chemically active components in a liquid system, said liquid system comprising water and chemically active components, said chemically active components including a polymer, said polymer being present in said liquid system as both bound polymer and free polymer, the method comprising:determining the level of said free polymer in said liquid system;determining the level of said total polymer in said liquid system, said total polymer comprising the sum of said bound polymer and said free polymer;calculating the polymer inhibition efficiency of said liquid system from the levels of free polymer and total polymer; andadjusting the rate at which a treatment solution is fed into said liquid system, said treatment solution comprising a known concentration of said polymer, to establish and maintain the polymer inhibition efficiency generally within a predetermined target range, whereby the concentration of the chemically active components in said liquid system is controlled.
