Reverse Osmosis Systems for Desalination &
Water Reuse
Wastewater Engineering Group supplies
a wide range of Reverse Osmosis Systems for water and wastewater
treatment.
Reverse osmosis is a process whereby the natural phenomenon of
osmosis is reversed by applying pressure to the concentrated side
of the semipermeable membrane. Reverse Osmosis Systems are widely
used for sea water desalination as an alternative of distillation.
Another important application of RO Systems is for brackish water
purification for municipal and industrial water reuse.
Seawater Reverse Osmosis (SWRO) Desalination Systems are designed
and used for desalination (i.e. removal reduce salinity) and producing
fresh potable water for drinking purpose and industrial usages.
In SWRO Systems, high pressure pumps are used to force seawater
to pass through a semi-permeable membrane, in the process water
is purified but contaminants and disolved solids cannot go through
and is rejected by the membrane. The purified product water is
also called permeate; the reject stream is also known as concentrate
or retentate.
Brackish Reverse Osmosis (BWRO) Systems brackish water (i.e.
not so high in salinity) is treated in a similar way, just that
driving pressure is not as high as applied in SWRO systems because
the Osmotic pressure that need to be counteracted is much lower
than that of the seawater.
Depending on capacities, sizes and applications, optimum array
arrangement design for reverse osmosis systems are designed by
us to suit the requirements of the customer. Wastewater Engineering
Group also provides energy saving type Reverse Osmosis Systems
and equipment for concerns of reducing customer's energy cost.
Our goal is to meet all requirements of our customers and we
excel in doing so.
Reverse Osmosis Development
There are some
- Osmotically Assisted Reverse Osmosis (OARO)
- Counter Flow
Reverse Osmosis (CFRO)
- Close Circuite Reverse Osmosis (CCRO)
- Reverse Direction Reverse Osmosis
- Batch or Semi-batch Reverse Osmosis
All these work arounds or variations processes are targeting on
different aspects around the Osmosis principle, and the RO membranes
properties, or operation conditions to achieve different objectives.
