Bromine Measurement
Alternatively to Chlorine compounds more and more Bromine compounds are used for the disinfection of waters, despite higher costs for reagents.
Compared to Chlorine compounds Bromine offers some advantages for disinfection purposes:
- Higher disinfection effect at higher pH values
- Lower volatility at higher temperatures
- Less promotion of corrosion
- Less generation of odours and irritation of the mucous membrane by abreacted Bromine compounds (compound Bromine)
Application areas
- Disinfection of cooling tower water
- Disinfection of swimming pool and whirl pool water on cruise liners
Organic and anorganic free Bromine chemicals are used generally for Bromine measurement. Organic Bromine chemicals are:
- DBDMH (1,3-Dibromine-5,5-Dimethyl-Hydantoin) labelled e.g. as Albrom 100® in trade
- BCDMH (1-Bromine-3-Chlorine-5,5-Dimethyl-Hydantoin) labelled e.g. as Bromine-Sticks® in trade.
These Bromine chemicals are offered as solid and are dosed as satured solutions via so-called "Bromine-locks".
Anorganic free Bromine is generated through the so-called Acti-Bromine-Procedure® (Acti-Brom-Verfahren®, Nalco) with Sodium Hypochlorite and Sodium bromide. The Bromine species can be present in various shapes and ambients depending on the type of the Bromine-containing disinfectant and the composition of the process water.
Our Program offers the following Advantages:
- Measurement of the Bromine reagent with the highest importance for disinfection
- Exact and reliable real time measurement
- Use in sensor technology in various water qualities (pH, salt content, temperature, filth charge)
- Easy modular integration in processes of all sensors required for the entire solution via suitable fittings
- Control devices with staged capacities adjusted to the requirements
- Easy calibration by means of the complete Photometer kit (type DT1, DPD-based method)
- For frequently arising tasks: complete standardized measuring and metering stations as plug&play modules with optimally inter-adjusted components.
