Water Purification Facility

Problem:
A large municipality provides city water from deep wells. EPA requires monitoring of levels of coliform bacteria, nitrates and lead in all well water supplies. These variables are monitored via a sophisticated system of instrumentation and monitoring equipment that capture ongoing data for future reference. Certain functions need to take place for filtration, chlorination and alarm notification when safe levels are not maintained.

Solution:
The municipality wanted to integrate displays into their monitoring system so employees could see at a glance the status of the wells. Data Masters LED Displays in NEMA 4X enclosures were integrated to display PPMs pH levels and any other variables that require chemical intervention to maintain a balanced system.

Data Source:
The monitoring equipment is a PC based system that continually logs data points via a data acquisition system. An ActiveX control was embedded in the data Aq system to communicate to the LED Displays via RS485.

ROI:
Savings were calculated to be over $10,000/year based on improved visibility of water condition. Payback for the displays was less than 4 months.
