pH Control

pH indicates the acid or alkaline effects of a medium as negative decadic logarithm of the H+ concentration and thus
determines crucially its chemical - and thereby its physical and biological - characteristics as well. Therefore, online measurement and control of the pH value is one of the most important tasks in process analytics. There are numerous applications in Water Treatment and in Production are spread over all branches. Here, great attention is paid to the neutralization (adjustment of pH value to pH 7) of acid or alkaline waters. This is especially true of effluent water treatment.

Efficient process guidance with synchronically high process safety requires precise, reliable and realtime pH measurement. and control. ProMinent offers a wide range of components for tailor-made, safe solutions:

• Various pH measurement and control devices for simple decentral solutions up to central solutions with integration in Profibus or CAN Bus.
• Numerous pH electrodes for the optimization of the precision / reaction time and lifetime of the process medium to be measured.
• Fittings for the installation of the electrodes in bypass lines, tanks, channels and pipelines adjusted to the process environment.
• Numerous metering pumps with capacity classes from laboratory scale up to large chemical processes, a large range of materials for medium compatibility, varying from simple editions up to electro-digital series with metering monitoring and connection to Profibus. Herefore, a comprehensive accessory range is available for the entire metering technology range.
• Tanks for storage and intermediate storage of chemicals in different materials and sizes up to 706 ft3 (20m³), also available with certification according to the German Federal Water Act. 
• Numerous metering pumps for transfering the media between the tanks.

High availability of the function has first priority when developing each single component. The aims are long lifetimes and minimal maintenance efforts.

Competent Support and Pre/After Sales & Service, all from one single supplier
Decades of experience make possible either the conception of the pH control or the entire Project. In each case the following conditions are taken into consideration:

• Operation of the pH control, either in charges or in the flow
• Selection and design of the pH Measuring /Control technology, pH -sensor and metering technology and tanks for acids and brines with regard to flow rate and consistence of the process medium.
• Installation, commissioning and servicing of the generators.

Cost-effective and Safe Standard Solutions for simple Applications
ProMinent offers completely standardized measuring and metering systems proven for years for frequently encountered applications. These compact plug & play modules are premounted, ready for operation and made of optimally coordinated components.
