Permeate quality
If permeate quality is not acceptable, one of the filter modules might have a defect
membrane. Identify the defect HP1 module by evaluating the permeate from each individual
module and isolate or replace the faulty module. Often, the visual appearance of the
permeate in the permeate tubing can reveal a damaged module.
