A closed dispensing system is defined as a system in which a product is transferred from a closed storage vessel to treated water without being exposed to the atmosphere, except in the case of normal ventilation or pressure relief.
Before putting the system into service, the operator should ensure that all residual cleaning agents are removed from the membrane surfaces by thorough rinsing.
