Conductivity Monitoring for Cooling Water Cycles
Author: Zhejiang Weilan Technology Co., Ltd.Source: Official sitePublished: Category: Technical Articles
Summary: Calculate cycles of concentration from online conductivity and interlock blowdown with dosing to save water and chemicals.
Cycles of concentration (COC) is the key economic metric for cooling water.
Principle
COC ≈ circulating conductivity ÷ makeup conductivity. Too low wastes water; too high invites scaling.
Control Strategy
Online conductivity → auto blowdown above setpoint → makeup dilution → inhibitor dosed proportionally to makeup.
Benefits
An optimal COC (typically 3-5) cuts makeup water by 20%+ and reduces chemical use. See the cooling water solution.
