From Craft calibration and the many pitfalls to these daily handles. In each water treatment facility of a public swimming pool needs to be done: Measuring and logging water chemistry. In previous articles, we have often discussed it, but always on the edge and not focused on the activities of calibration.
The advantages of membrane-covered amperometric sensors
If we talk about disinfection, then most people immediately think of "chlorine". Here is often overlooked, that chlorine in different forms occurs. While the right eye can be protected by "free chlorine" for infections, is the left eye may be the result of bounded chlorine and his children in the air. This bound chlorine is the reason for the bad taste and smell in the air - but has very little to do with the disinfection or our protection. Membrane-covered sensors can also detect this kind of chlorines.
The selection of membrane-covered amperometric sensors
Tutorial to choose Membrane covered amperometric sensors with detailed explanations of the parameters. In this table, you can select the correct sensor. In the footer of the table filter can be written, which restricts the number of rows. Please also note the informations, which will be displayed in the right columns by horizontal scrolling. Find out in the fields measuring size, Subgroup, Measuring range, Measuring water, Pressure, pH range, Temperature, Cross sensitivity, Reaction time, Connections, Downloads, about the existing possibilities and conditions.

baua document subject to new biocide:
Scope of the new biocide, 2013, Federal Institute for Occupational Safety and Health, baua:, Lena Gruhn Am 1. September 2013 releases the new biocide regulation (EU) No. 528/2012 the former Directive 98/8/EC as from. The new regulation allows new registration procedures, For example, the Union authorization or the authorization of product families. For products with a low environmental- and health profile a simplified method is provided. In addition, now treated with biocides goods is recognized. In addition to new labeling requirements may contain only active substances, which are marketable in the European Union.

Guideline for sanitary assessment of organic materials in contact with potable water (KTW-Guideline)
1 scope of application, 1.1 Validity of this guideline, This guideline provides hygienic requirements for plastics and silicones, which are used in contact with drinking water. This Guideline replaces the KTW Guideline of 07. October 2008. You can for hygienic assessment of plastics, such as polyethylene, polypropylene, Polybuten, Polyvinylchlorid, chlorinated polyvinyl chloride, cross-linked polyethylene, polyamide, Polyurethan, Polyester, be used as well as silicones. It also contains provisions for evaluating the test according to DIN EN 16421 for proof of hygienic safety with regard to a microbial growth.
Pool construction types 02 Theorems
1. Quotation DIN 19643, section 4: “For disinfecting, a germ killing of Pseudomonas aeruginosa by four orders of magnitude was within 30 s used.” Even if you think, this sentence could not relate to the swimming pool: This theorem is the basis of any further consideration! This theorem describes the effect of the disinfectant chlorine at a concentration of between 0,3 and 0.6 mg/l. All other theorems are built up on this foundation. This theorem is also true for water treatment.
