摘要： A device that detects the presence of surfactant residues utilizes a motion-based camphor test to detect surfactant(s) and surface-active molecules. The device, also referred to as a camphor-based dynamic tensiometer, can be used to detect desirable and/or undesirable surfactant(s). For example, surfactants used for membrane cleaning, as surface active ingredients, need to be rinse out of surfaces. Especially for porous membranes the rinsing of the Permeate side is water-intensive, since the huge membrane area of the porous structure. Thus, a camphor-based dynamic tensiometer can be automated to determine end of rinse in systems that utilize CIP chemistries containing surfactant(s). Proper rinse of CIP chemistry(ies) is key while removing the cleaning chemistry and balancing on the other hand water spent for the rinse, as membranes are difficult to rinse due to the porosity of the membrane towards the permeate site and the big inner surface of the porous structure.
