SPIRAX SARCO Cut Steam Boiler Costs With Zero-Loss Reverse Osmosis

An innovative steam boiler water treatment technology from Spirax Sarco uses reverse osmosis (RO), enabling steam users to achieve a step-change in energy efficiency.

RO is a robust, chemical-free technology that uses semi-permeable membranes to deliver purified water to boilers and clean steam generators. It can strip out between 98 and 99% of the total dissolved solids (TDS) in the feed water, slashing the boiler blowdown rate to less than 1% and knocking between 1 and 3% off fuel bills.

Where conventional RO water treatment systems reject approximately a third of the water that passes through them, Spirax Sarco’s unique zero-loss systems use an innovative approach to eliminate virtually all waste water. This alone saves typical steam users 2-3% of fuel costs.

Combined with other savings, such as reducing the need for chemical water treatments, Spirax Sarco RO systems will usually pay for themselves in well under a year, and sometimes in six months.

Elsewhere in the steam system, RO helps cut down on plant outages by reducing corrosion in the condensate circuit caused by the build-up of carbonic acid, provided it’s used with the right complementary treatments.

So just what is RO? Osmosis is a natural phenomenon that controls the flow of fluid across a semi-permeable membrane barrier. It balances the flow of fluid and nutrients across every cell wall in our bodies, for example. With RO a pump is used to apply pressure and force the natural process into reverse. The pump effectively forces a concentrated stream of salts is forced through a membrane into two streams. One stream is the reject stream or concentrate stream, the other is the sought after pure water (permeate) stream. RO is a safe way of producing pure water because it doesn’t need the acid or caustic regenerants used in conventional demineralisation plants.

RO systems comprise a pressure pump, housing and membrane. Water is pumped into the RO system under pressure and the pure water (or permeate) is forced out, directly into either a hotwell or permeate holding tank. In steam applications, the boiler or clean steam generator would be the next stop. The biggest cost of running an RO system is the energy needed to pump the water, so Spirax Sarco uses optimised, composite membranes and smaller, more efficient pumps that minimise the pumping energy needed.

Anyone concerned that introducing a new technology might involve adding substantially to the maintenance burden can stop worrying. Provided the water entering the RO system is properly treated, the robust membranes are very low-maintenance. And if they are damaged they’re easy to replace.
