Reliance on manual intervention was limiting system performance.
The CIP (Clean-In-Place) system maintains the internal hygiene of process equipment through cleaning cycles using caustic solutions, its highly alkaline effluents require a reliable neutralization process before final disposal to ensure regulatory compliance and operational continuity.
A food and beverage plant needed to optimize its neutralization system, the operation, based on CO₂ injection, relied on manual intervention and basic reactive controls, creating environmental challenges and risks to safety, continuity, and operational efficiency.

An integrated strategy based on three pillars
Optimized CO₂ Reaction The injection system was redesigned using a distributor with 11 diffusers and a mass transfer strategy that improves contact between the CO₂ and the effluent, ensuring that each gas dose is used more efficiently, reducing consumption and accelerating neutralization,
Continuous Real-Time Measurement High-precision instrumentation was incorporated, including inline pH transmitters to continuously monitor the process status, measurement was no longer dependent on the operator and instead became the variable that controls the neutralization process,
SCADA Automation and Integration The entire operating logic was integrated into a PLC/HMI system connected to SCADA, the system automatically executes the filling, neutralization, and draining sequences, controls valves and flow paths, monitors levels, and enables real-time process visualization from a single platform,
