Long-lasting performance during whey processing
pH monitoring with non-glass sensor Memosens CPS77E
The food industry and as well the processors of whey rely on unconditional safety in their processes. When separating valuable whey components, the process is subject to strict specifications and high requirements for cleaning.Therefore, the pH values must be
closely monitored.
Results
Robust ISFET sensor which lasts for more than 300 cleaning cycles
Accurate data is provided to ensure the product quality and safety
Maximum process safety through non-contact inductive signal transmission
High product safety due to a shatterproof glass-free sensor
Reliable pH sensors guaranteeing the integrity and operation efficency of the polymer and ceramic membranes
Challenge
The membrane modules are the heart of the separation process, they allow an efficient process. All demands must be fulfilled for this. One critical point is cleaning, here the pH value must be strictly monitored. The membranes are made of polymer or ceramic. Cleaning process varies depending on the material. Polymer membranes have special requirements in terms of temperature and chemicals. Ceramic membranes are cleaned with a caustic solution.
Our solution
The CPS77E is used to monitor the pH value. In the plant sections fitted with polymer membranes, the sensor is installed in-line and cleaned during the cleaning process. The ceramic sensors are installed with a retractable assembly to protect the sensor from cleaning with caustic solution. The sensor is cleaned in the laboratory. In both cases, the pH is reliably monitored throughout the process so that damage to the membranes is avoided and the separation process proceeds as desired.
