full range of water treatment processes from Micro and Ultra filtration
systems to Reverse Osmosis.
Osmosis (RO) Technology
Osmosis (RO) is recognized by
as the best technology available to remove the widest
spectrum of contaminants found in drinking water
(e.g. bacteria, virus,
arsenic, suspended solids, dissolved heavy metals and chemicals,
contaminants, salts and other impurities).

RO is the process by which water molecules are forced through
0.0001 micron semi-permeable membrane by water pressure. Long sheets of
membrane are sandwiched together and rolled up around a
hollow central tube in spiral fashion, commonly referred to as
spiral wound membrane. RO membranes are
available in different sizes for processing different quantities of
The RO membrane is housed in a housing so that pressure can be
maintained on its surface. This pressure forces the water through the
membrane, separating it from the unwanted substances like dissolved
chemicals, heavy metals, suspended solids, arsenic, salts and
other impurities. These unwanted substances are diverted to a reject
drain so that they do not build up in the system, thus keeping the RO
membrane clean and prolonging the membrane life.
The UltraPure range of industrial and
commercial RO systems uses Ultra
Low Pressure Reverse Osmosis membranes. These membranes can
operated at significantly lower operating water pressure compared to
conventional reverse osmosis membranes,
yet achieving good removal of unwanted substances and
output flow rate.
Often, an RO system comes with pre-filtration
tailored to the application, including melt-blown, sediment, carbon and
string-wound pre-filters. This is to provide sufficient protection for
membrane and prolong its life. Some systems also include post treatment
like granular activated carbon (GAC).
The quality of RO water is easily measured using a TDS meter
or test pen.
It is measured in PPM (parts per million) of total dissolved solids
(TDS) in the water.

Traditionally, UF membranes were only used in high end and critical
applications like municipal water treatment plants, hospitals and
pharmaceutical industries. But due to advances in technology, the cost
