Radium Compliance Achieved with Ion Exchange Technology – Water World
By Joseph Sanchez Several Ion Exchange Plants have been commissioned in Romeoville, IL, to improve its water quality by reducing existing levels of radium in the drinking water below requirements mandated by the Environmental Protection Agency.
Located 30 minutes southwest of Chicago, the Village of Romeoville draws its water from a ground water supply consisting of five deep wells with pump settings of approximately 1,500 ft. below the surface and seven shallow wells pumping 150-300 ft. below the surface. The village pumps over 3.8 million gallons a day to over 50,000 residents in the suburb and nearby service areas, which totals over 1.4 billion gallons a year.

In compliance with EPA regulations, the village conducts quarterly water sample testing. The quarterly tests had revealed slightly elevated levels of radium (226 and 228) in the aquifer from which the village draws most of its water supply. The radium levels exceeded the Illinois Environmental Protection Agency’s maximum level of 5 picocuries per liter or pCi/L.
Programming Console is a programming panel in which there RAM (Random Access Memory) that functions as a semi-permanent storage in a program that was created or modified. Programs written to the console must be in the form of mnemonic. This device can be connected directly to the CPU by using a cable that can be installed ekstention and removed at any time.
Memory is a component for storing the program, To the PLC will work as expected then needed a program to run it. The program should be stored in a certain way so that the PLC can access commands according to the instructions. One also needed to store data temporarily during the implementation of the program.
