| General |
MSI offers packaged Brackish Water RO Systems using the latest in membrane
technology and state-of-the-art control systems. Capacities range
from 100 - 600 m3/day (18 - 110 gpm), Permeate Recovery 50-75%
and Operating Pressure 10 - 31 Barg (150 - 450 psig)
Note:
Rated capacities are based on 2,000 ppm NaCl Solution @ 25 oC (77
oF); Operating Pressure 10 - 17 Barg (150 - 250 psig)
for Thin Film Composite (TFC) membranes and 27 - 31 Barg (400 - 450 psig)
for Cellulose Acetate (CA) membranes; and 50-75% Permeate Recovery,
depending on feed water chemistry and system size.

Equipment |
The Packaged
system is skid mounted and self contained. The Medium Pressure
Pump (MPP), Micron Filter, Low and High Pressure Piping as well as
the Instrumentation and Controls are all mounted on the
skid. Local Control Panel (LCP) and Motor Starter Panel (MSP)
are also mounted on the same skid. Cleaning
System can be mounted on the BWRO frame or furnished as a separate
skid. Up
to Three Chemical Pretreatment and Post Treatment Systems are
provided as standard feature, and can be mounted on the BWRO frame
or provided separately. |
