Multiparameter real-time monitoring of reverse osmosis feedwater and permeate is demonstrated as an effective tool for optimizing system efficiency and reducing chemical costs. Using ultra-low-range chlorine analysis, turbidity monitoring, and biofilm detection sensors integrated with intelligent water management software, a food production facility achieved significant cost savings and improved operational control. Direct measurement of residual chlorine after dechlorination enabled treatment program adjustment, while turbidity trending revealed fouling issues attributable to microfiltration cartridge degradation. The study reveals that >80% of total chlorine residual exists as chloramines rather than free chlorine, providing critical insight for dechlorination control. Implementation resulted in $3,353 direct chemical cost savings and projected annual savings of $6,700 through optimized chemical dosing strategies.
