Thanks for all the replies. When I first came to this job the cleaning interval was 60 days, I got it pushed to 90, then 120. I kept arguing that our makeup water is essentially mineral free, and the boiler is self sanitizing, therefore no scale, and no bio load. I argued for a couple of...
We have a small Electric boiler at our facility. It is used to produce "clean" steam for sterilization of some piping and a couple small production machines. It is fed with RODI water with conductivities less than 1.00 microS/cm. We have always cleaned it with a citric acid based cleaner. This...
We generally do medical devices, wound washes, eye washes, and the like. Some with PW, some WFI as the major component. This product was to be an energy drink concentrate made with a flavoring and PW. The concentrated flavorings apparently are a real bear to clean. Thus management's desire to...
All of my experience is in the pharma field, but our facility has a shot at a small food grade project. We have a process tank that has been out of use for a while and the admin folks want to use it for this project. The problem is this tank has ANSI style flanges on all of its nozzles, and from...
The steady water use statement has to do with the fact that in the case of our system, if we just circulate water in the distribution loop, and don't use it for processing, I see a steady rise in conductivity over the course of days. I attribute this to our ozone generation system more than...
I maintain a similar system to what you describe, and from our investigation of the same phenomenon, the mere fact of adding water to the PW storage tank on the distribution system will cause the conductivity to rise by a couple tenths. circulation in the distribution loop will cost a couple...
I manage a small RODI system that feeds our PW distribution loop. It has a capacity of 4-5 GPM USP PW. My associate and I have been kicking around ideas for how to either get some work out of, or reuse the RO waste stream. We tried a little trial run of using the waste stream as coolant through...
Thanks for your reply. No nothing of the kind. In looking into the colorimetric method that we use to measure these values, I found that this test can be influenced by a number of different metals, including Cr. The pump having a number of 314L parts, might be giving up some chromium due to...
As part of our PW system, we have a break tank and recirc loop that we installed to isolate our pre-treatment zone from the the municipal mains. The wildly fluctuating pressure of the city water was playing havoc with our softeners mostly. The oddity we have been experiencing is elevated...
