Savings with reverse osmosis

Published:  26 February, 2014

Westons Cider is said to be saving around £42,000 per year in fuel and water costs following the installation of a Reverse Osmosis (RO) water treatment unit from SPIRAX SARCO.

The new RO system has reduced water and energy losses by cutting the amount of boiler blowdown and water needed. Accurate metering of fuel oil and water has pinpointed the savings, including 3,800 litres of oil saved over a 15-day period.

Regular boiler blowdown is needed to prevent dissolved solids from accumulating in the boiler, where they can cause problems such as foaming and scale. The RO system from Spirax Sarco treats water before it reaches the boiler feedtank and is reported to remove more than 98% of contamination to produce high-quality, low-conductivity water.

The project has shown a step-change in control and efficiency and has enabled an increase in the boiler cycles of concentration, resulting in reduced boiler make up and boiler blowdown.
