The Grundfos BME / BMET / BMEX pump systems are suitable for water treatment applications handling seawater and brackish water desalination. All pump materials which are in contact with the seawater are made from 904L or duplex stainless steel. In addition, the materials in contact with water in the pressure exchanger are made from duplex stainless steel and ceramic. The BMET booster system consists of:
a BME high pressure feed pump
a BM high pressure turbine pump
The BMEX booster system consists of:
a BME high pressure feed pump
one or more X-Changers
a BM high pressure ciculation pump of high-grade stainless steel
a Variable Frequency Drive
The BME / BMET and BMEX booster systems are based on the hydraulics of Grundfos SP_R submersible pumps and an ERD (Energy Recovery Device). The booster system is used for:
desalination of sea water in reverse osmosis systemt, i.e. SWRO systemts (SWRO = Sea Water Reverse Osmosis).
Applications
Desalination of brackish water and seawater.
Features and benefits
Energy recovery up to 60 %, compared to conventional systems, resulting in short payback period
Corrosion- and wear-resistant internal ceramic components
