An autopsy is a procedure during which a piece of equipment is opened and any problem(s) identified.  DHP performs:

  • Reverse Osmosis (RO) Membrane Element/Module Autopsies
  • Nanofiltration (NF) Membrane Element/Module Autopsies
  • Ultrafiltration (UF) Module Autopsies
  • Microfiltration (MF) Module Autopsies
  • Electrodeionization (EDI) Module Autopsies


DHP has provided autopsy services for high-tech water treatment systems since the early 1990s.  DHP has performed many hundreds of autopsies.



Others’ Autopsies

Most reverse osmosis (RO) and nanofiltration (NF) membrane element autopsies are performed by membrane manufacturers and membrane water treatment chemical vendors.  This is because if you’re a good client, you may get an autopsy for free.  But there may be a conflict of interest.  If there are membrane manufacturing defects, the manufacturer may downplay these.  If there are fouling or scaling problems due to chemical injection issues, the chemical vendor may downplay these.


Manufacturing Defects






Chemical Injection Defects




Most others’ autopsies:

  • Identity only the problem(s) found
  • Don’t evaluate the conditions at which the element operated
  • Take 3-4 weeks or more to provide you with a report

David H. Paul, Inc. (DHP) is the world’s leader in high-tech water treatment training.  DHP doesn’t sell chemicals or membrane elements.  DHP has performed hundreds of RO and NF element autopsies since 1988.
