Reverse Osmosis (RO) Desalination: Automated Permeate Flushing & Membrane Protection

Automating industrial RO skids: high-pressure pump VFD ramping, automated permeate flush on shutdown, differential pressure (dP) fouling tracking, and conductivity rejection interlocking.

  • High-pressure RO pumps (40 to 70 bar) require smooth VFD acceleration ramps to prevent hydraulic water hammer from destroying membranes.
  • If high-salinity feed water sits stagnant inside membranes during shutdowns, minerals precipitate and scale pores.
  • The automated shutdown sequence flushes high-purity permeate water through the vessels before valves isolate.
