Intermediate Water Treatment builds on the knowledge of water chemistry, risks to coffee equipment, and simple treatment methods introduced in the Water & Preventive Maintenance Foundation course. In IWT, learners will deepen their understanding of water treatment system components and processing capacities, principles of limescale buildup and corrosion risk, and system requirements for various coffee equipment types. Hands-on activities include the assembly, installation, adjustment, and maintenance of water treatment systems and the use of various measurement devices and techniques.
