Good Example of Improper Water Treatment Chemical Feed Location

Find more great water treatment resources at www.ClarityWaterTech.com This is a great example of a water treatment chemical feed station in a chiller plant where the chemicals are NOT being fed properly. The video shows four drums, but there are only three chemicals being fed into the system: a corrosion inhibitor, a non-oxidizing biocide and an oxidizing biocide. At Clarity Water Technologies, our water treatment professionals run into this situation very often. One of the first things that we evaluate is "Is the water treatment chemistry being fed properly, in the correct dosages and in the correct locations?" In this video we can see that there is probably a better way. Video Transcript: One of the issues that we see very often at Clarity Water Technologies is that when we survey a facility for the first time the chemicals are sometimes fed incorrectly. The water treatment company may be using the correct chemistry, however it's just not being fed properly; and here we have a very good example of that. This is a chemical feed station in a chiller plant. The water treatment company correctly set up a corrosion inhibitor and dual biocide program to protect the system, including its chiller and its cooling towers. However, if you look at how the chemicals are being fed into the system you can see that the chemical tubing leading from the metering pumps are being fed side-by-side, very closely into a small three-quarter inch PVC pipe, which we can see runs a very long distance throughout the mechanical room and eventually up into the common header. Unfortunately, having all three of those chemicals running together in such a small pipe could cause all kinds of issues including reactions between the chemicals; or a reduction in efficacy of the individual chemicals; if you don't have the flow in that small pipe the chemicals could just sit there and never even make it into the system altogether, or even further clog the small pipe. But instead, these three chemicals should have their own separate entry points into the common header; ideally these three location should be eighteen to twenty four inches apart and should fall after the chiller but before the cooling tower so now you would have these three chemical tubes running directly into three separate stingers that go directly into the common header where there will rarely, if ever, be a problem with flow; and therefore, no problems with proper chemical disbursement throughout the entire system.
