Water treatment systems that electrolytically generate copper and silver ions for the control of bacteria (including planktonic legionnella) in hot and cold water systems are becoming more and more common. Silver concentration should be a minimum of 20ppb and higher with hard water feed. It is important that installers of ionisation systems take into consideration regulations on maximum allowable copper and silver levels (The Water Supply (Water Quality) Regulations), as well as local water quality.

Hardness and pH are two important factors that can affect the efficiency of the whole process. Copper ions are also required to complete the synergy. To perform an analysis, simply add a reagent sachet to 50ml of sample water; filter this through a small membrane and compare the colour of the membrane with the standard colour chart. The test takes just a few minutes to complete, ensuring correct operating conditions. Ideal for checking sentinel outlets on a monthly basis and representative taps on a rotational basis.

Copper HR Colorimeter
The Copper HR Colorimeter is a simple, accurate and cost effective way to measure high ranges of copper. Designed as a more accurate alternative to chemical tests, the Colorimeter provides quick, accurate results in four easy steps. The Colorimeter uses an adaptation of the EPA method. The reaction between copper and the reagent causes a purple tint in the sample.

Silver Iron Photometer
The Silver Ion Photometer is a small, lightweight digital photometer, specifically designed to accurately measure silver ions in water. The Photometer features an advanced optical system; the combination of a special 570nm LED lamp, a narrow band interference filter, and silicon photocell ensuring accurate photometric readings every time. It is currently the easiest to use, quickest and most accurate silver ion measurement tool on the market. Using the highly accurate span calibration method for faster more accurate results than conventional silver ion meters.
