255 Pinks And Blues: Testing for Halogen in A Water System
b'
We\'re going to dive right in to listener questions in this Pinks and Blues episode because today is all about testing for Chlorine. Chlorine is the most well-known of the Halogen elements, a group of Oxidizing Agents. So, if you catch me using these words interchangeably, it\\u2019s because they are!
As a quick chemistry refresher, a Halogen is the chemical that forms a salt when it reacts with a metal. There are 5 Halogens in the Periodic Table: Fluorine, Chlorine, Bromine, Iodine, and Astatine and you can \\xa0find the whole column of Halogens the column second furthest to the right.
In Cooling Towers, we typically use Chlorine or Bromine. By the way, whatever you use, make sure it is registered for that usage. There are two methods of testing Halogen: OT (Orthotolidine) and DPD (N, N-diethyl-p-phenylenediamine), which is the method many of us prefer because it allows us to have a free or total test. Are you curious yet about testing for Halogens?
Today, we are going to talk about all things Halogens. From differentiating the types of Halogens, to understanding the different testing methods, and to the importance of having a Water Management Plan to make our jobs easier.
Bottom line: Let\\u2019s learn about testing for Halogen in a Water System.

Thinking On Water With James:
In this week\\u2019s episode, we\\u2019re thinking about whether the brine tank on your softener system reaches 100% saturation between softener regenerations. Do you know? Have you ever measured % brine saturation in your brine? How would you measure % saturation? When is the best time to measure it? If it is not reaching 100% saturation, can anything be done to improve it? What is the impact upon softener regeneration with less than 100% brine saturation? Take this week to think about the % brine saturation in your softener system\\u2019s brine tank.\\xa0

Quotes:
\\u201cA Halogen is a chemical that forms a salt when it reacts with a metal, and there are five Halogens in the Periodic Table: Fluorine, Chlorine, Bromine, Iodine, and Astatine.\\u201d - Trace Blackmore
\\u201cHalogens are highly reactive, which means they are quick to form bonds with other elements.\\u201d\\xa0 - Trace Blackmore
\\u201cOxidizers are solids, liquids, or gasses that react readily with most Organic Materials or Reducing Agents with very little energy that has to go into them.\\u201d - Trace Blackmore
\\u201cA Reducing Agent is a substance that can be oxidized by losing some of its electrons. An Oxidizing Agent is a substance that can be reduced by gaining electrons.\\u201d - Trace Blackmore
\\u201cWe generally use Chlorine or Bromine, and we will commonly hear them referred to as either Oxidizers or Halogens.\\u201d - Trace Blackmore
\\u201cWhat Halogens are you using, and why are you using those?\\u201d - Trace Blackmore
\\u201cThe OT Test (Orthotolidine) \\xa0only tests for Total Halogen.\\u201d - Trace Blackmore
\\u201cThe DPD Method (N, N-diethyl-p-phenylenediamine) can test for both Free and Total Halogen.\\u201d - Trace Blackmore
\\u201cYour Tests are your Tools. Don\\u2019t run your Test, and have your test tell you what to do next. Your Test only confirms or disproves any theory that you have.\\u201d - Trace Blackmore
\\u201cDiagnose first and then use a test to confirm.\\u201d - Trace Blackmore
\\u201cFree (Halogen) is the amount of Oxidizer in the system that hasn\'t been combined with anything yet. It is Free to react; therefore Free is the amount of quick kill agent you have in your system to sanitize contaminants\\u201d - Trace Blackmore
\\u201cThe Total Oxidizer is the amount of Free Oxidizer that you have plus the amount of Oxidizer that has combined with other Contaminants. So Free + Combined = Total\\u201d - Trace Blackmore
\\u201cCombined Oxidizer is the amount of\\xa0 Oxidizers that has combined with Organics.\\u201d - Trace Blackmore
\\u201cMake sure that whatever you are using is registered for that intended use.\\u201d\\xa0 - Trace Blackmore
