WatPro offers powerful features to help you obtain timely information:
     •  SCADA system links for continuous system performance monitoring
     •  sensitivity analysis to evaluate the effects of chemical or process changes
     •  site-specific calibratable chemical reaction rates (e.g. chlorine decay)
     •  user-formatted reports

Potentially carcinogenic disinfection by-products (DBPs) are a growing concern for water utilities as regulations such as the Disinfection-Disinfection By-Product Rule impose more stringent DBP limits. In addition, compliance may be difficult and costly to achieve while maximizing disinfection efficiency for Giardia and Viruses. WatPro is a water treatment plant simulator which can be calibrated specifically for your plant and can help you manage your treatment process to balance compliance with both DBP and microbial regulations while achieving potential cost savings.

WatPro and inactivation of E. coli bacteria
WatPro allows users to track Ct at all locations in a treatment plant

Here is why you should be working with WatPro right now!

A deadly microbial invasion in a Canadian water distribution system has tragically illustrated the need to ensure that consumer tap water is absolutely safe. WatPro can show whether pathogenic bacteria like E. coli 0157:H7 have been adequately inactivated in a water treatment plant. For an uninterrupted primary disinfectant dosage rate, WatPro tracks the inactivation of viruses and Giardia by disinfectant addition.

Because fecal coliform bacteria are inactivated by disinfectants to a greater extent than viruses, the log reduction of bacteria like E. coli will match or exceed the reduction for viruses calculated by WatPro.

The simulator also determines the Ct disinfection parameter at any location in the treatment plant.
