Savings and sustainability

About 30m3/h of water was not being used. Veolia’s RecoBLUE online calculator showed they could recover about 50% of the reverse osmosis losses, at a quality of better than 120µS/cm conductivity, which would be suitable for use as boiler make-up.

It was essential that the recycling process should not increase energy and chemical consumption, so Veolia provided a specially configured Sirion Mega Recovery RO Unit. Veolia’s system requires no additional chemical dosing for conditioning prior to recovery. With low pressure, high rejection membranes, the Sirion Mega Recovery system has low energy consumption which minimises its carbon footprint and operating costs.

The new system is performing as predicted by the RecoBLUE calculator and is reducing the Cider Mill’s water footprint by more than 130,000m3 per year of water. The resulting annual saving of more than £100,000 will repay the system’s capital cost in less than four years.
