pH Control
pH Control refers to the process of managing and adjusting the acidity or alkalinity levels in industrial processes and manufacturing. Think of it like maintaining the perfect balance in a swimming pool, but for industrial operations. Chemical engineers use this skill to ensure product quality, safety, and efficiency in various industries like food production, water treatment, pharmaceuticals, and manufacturing. This is a fundamental skill that appears frequently in chemical engineering job descriptions, similar to how a chef needs to understand temperature control in cooking.
