Standard Products - MSS and MSD Feed Pumps with HPB

  • Thousands of units in SWRO Service
  • RO Feed Pumps with Energy Recovery Pressure Boosters
  • Feed flows from 7.5 to 560 m3/h
  • Pressures to 83 bar (optional to 110 bar on some models)
  1. Low pressure feed from pretreatment
  2. HPP raises feed to an intermediate pressure
  3. HPB raises feed to membrane requirements
  4. High pressure brine
  5. Low pressure to brine drain
  6. Permeate

Feed Booster Configuration

Simply start the pretreatment system, flush air from the membrane, start the HP pump and startup is complete. Adjust feed and brine flow for desired recovery.

HPB shown mounted on optional extended pump base plate. HPB may also be located anywhere in the RO system to minimize piping runs.

  1. High pressure feed from HPP
  2. 1st stage brine
  3. HBP raises feed to 2nd stage requirements
  4. High pressure brine
  5. Low pressure to brine drain

 

Interstage Boosting Configuration

Interstage boosting balances flux rates, improves permeate quality and overall production. With optimized array design, interstage boosting can provide energy efficiency as good as any other type of ERD.
