Process Overview pH Control
The pH value is one of the most important chemical values. Determination and control of pH is standard in many industrial applications, in water treatment and in quality control of liquids.
The desired pH value can be precisely adjusted by the addition of acid or alkali. An absolute must, particularly in neutralisation processes with stringent requirements for reliability and accuracy. ProMinent offers the right solutions for this – whether as an inline or batch process, as a stand-alone dosing station, or linked to a central control system
via PROFIBUS®.
Complete solutions from storage of acids and alkalis, through dosing equipment, to matched measurement and control equipment:
- Dosing stations for acids and alkalis
- Dosing pumps suitable for all media and dosing capacities
- pH electrodes for fitting in by-pass, exchangeable and immersion housings, or direct in pipelines for flexible process connection
- Controllers with extensive functions, optimally matched to sensor technology and dosing equipment, or simple transmitters, with PROFIBUS® interface too, for tailor-made control loop setup
- For standard configurations: measuring and dosing stations available as Plug & Play modules
- Complete neutralisation plants supplied pre-assembled and ready for operation
