Chemical Dosing, Water Heating, and Water Reclamation Systems

Designed for field service technicians, this course delivers comprehensive training on fluid handling subsystems critical to automated wash quality and environmental compliance. Learners explore the physics and mechanics of chemical injection systems, including venturi eductors, positive-displacement dosing pumps, and automated proportioning manifolds. The curriculum details commercial water heating infrastructure, focusing on boiler operation, heat exchanger maintenance, combustion safety controls, and thermal efficiency. Additionally, technicians examine closed-loop water reclamation networks, covering hydrocyclone grit separation, settling pits, aeration, multi-media filtration, and odor control chemistry. Through systematic diagnostic methodologies and safety procedures, students learn to balance water chemistry, troubleshoot delivery fluctuations, and service high-volume reclamation components to ensure wash quality while minimizing operational costs. Practical diagnostic strategies emphasize preventative maintenance, component replacement protocols, and fluid flow optimization, equipping students with the technical acumen needed to sustain dependable wash performance under high-volume commercial operating conditions.
