Reverse Osmosis System

The purpose of this amendment is to answer a question and attach a picture. No other questions are allowed. Q. what programming logic is needed to connect (ie. 420 ma/120 VAC/internet protocol) will be needed. Will this tie into an existing PLC or will it be a stand alone system? A. The system is a stand alone unit. All functionality of the Centra (big blue box) is internal, with only mechanical connections to the peripherals and the distribution plumbing.

The system does have the capability to connect to the internet for remote monitoring. If we choose to do this, our IT will purchase any interface items necessary. The U.S. Geological Survey (USGS) is conducting market research to determine the availability of qualified businesses capable of providing a Reverse Osmosis System as described in the required features and specifications below.
