Chemical Injection Systems, Water Treatment, and Laundry Plant Utilities
This course equips commercial laundry technicians with the core competencies required to service chemical injection systems and balance facility utilities. Students examine peristaltic pumps, pneumatic injection systems, venturi injectors, and flush manifold designs integrated with industrial washing machines. The curriculum addresses incoming water conditioning, including water softening chemistry, filtration, temperature stabilization, and flow balancing, alongside effluent handling and heat recovery equipment. Technicians also master utility distribution networks encompassing compressed air generation, steam regulation, condensate recovery, and backflow prevention. Emphasizing safety, environmental standards, and resource conservation, students learn diagnostic methods for metering faults, hydraulic imbalances, and utility drops. Through hands-on laboratory exercises and diagnostic scenarios, learners configure delivery manifolds, calibrate electronic chemical flowmeters, balance utility feeds, and complete system-wide service audits to ensure maximum wash formula efficiency and facility reliability across high-volume production plants.
