and Control Equipment
Customers are now looking to control their processes and the effluent from their processes more exactly to reduce costs, reduce effluent and improve quality.
PreTreat are able to supply, fit and set up chemical controllers for process tanks and rinses and continue to support the customer through any problems.
Rinse Water – Control rinse waters to save money. In many applications customers have a controller for the rinse stage operation.
This installation reduces water consumption by 33%, and ensures the quality of the water is adequate for chemical processing.
Operator error is eliminated, as the units are controlled by the same power source as the main plant.
Quality improves as well; many cases of osmotic blistering formation have been overcome by controlling poor rinse water.
Chemical Dosing Equipment
Automatic Ion Control is an accurate and reliable method for automatic control of metal treatment baths, using the latest technology.
Installation is quick and simple, and minimal subsequent operator involvement leads to a cost-effective means of running a metal treatment process which is relatively free of human error.
The benefits of installation include:
- Peace of mind the chemical solution is at the correct operating strength.
- Immersion and spray applications can be controlled accurately.
- No handling of chemicals by operators.
- Each unit is a bespoke manufacture suitable to customer’s individual needs.

Automatic Ion Control uses an ionic sensor to assess the % concentration or activity in a process bath. In general, normal operation is in % Concentration Mode, which relies on the correlation between changes in ionic mobility in solution and any change in concentration of the process bath.
The use of the ionic sensor in alkaline etch baths presents a relatively complex situation, due to the various chemical equilibria involved. For this type of bath, the meter operates in Activity Mode, which allows compensation for the different activity coefficients of the ions in solution.
After initial calibration for the specific concentration and temperature of the bath, the operation is virtually maintenance free.
