Online Disinfection Manager (ODM)

CT requirements continually change with water conditions, and disinfectant doses should reflect these changes. The Online Disinfection Manager (ODM) automatically calculates the right concentration for current conditions. A simple, fast and easy to use unit converter built specifically for wastewater professionals. WaterUnits offers unit conversion between various common Metric (SI) and Imperial (US) water and wastewater units and also allows users to add their own.

In North America many drinking water treatment plants determine their CT requirements using worst case month or even annual PH, Temp and flow rate values. This results in costly disinfectant overdosing and the formation of unnecessary and dangerous disinfection by-products (DBPs).

ODM (Online Disinfection Manager) was developed by Hydromantis Inc., to give plant operations staff a tool to allow them to better manager the operation of their facility and thus provide a safer drinking water with minimum DBPs. ODM automatically calculates the right concentration of chemical dosage required for current conditions using real-time data. ODM utilizes WatPro linked with online sensors and to provide real-time tracking of disinfection performance. Plant operations staff utilize output from ODM predictions to help optimize chemical dosage.

Success Stories

Recent success at the City of Toronto Horgan treatment plant demonstrated ODM could save significant chemical costs and help maintain a safe drinking water quality. The Ontario Ministry of the Environment (MOE) verified it’s ability as a tool to optimize plant operations at Horgan.
