FROTEC BW-8040 / BW-4040 high pressure membrane
FROTEC BW-8040 / BW-4040 elements can separate salts from water and increase permeability while offering superior salt rejection. They are ideal for use in large-scale industrial and municipal water treatment systems.
FROTEC BW-8040 / BW-4040 elements can lower the cost of desalination by improving energy efficiency and productivity significantly.
new-built or existing RO systems.
high quality permeate while minimizing unit cost.
various operating conditions with 4″and 8″elements.
