## Sceptre DS130 Dosing System in the UAE

UAE mains water is desalinated and fairly soft, with total dissolved solids around 254 mg/l in Dubai. RO takes it lower still, so many drinking and coffee systems add minerals back to get the taste and balance right.

On sites fed by tanker or wells, the job flips: water can be far harder than the mains, and an antiscalant protects the RO membranes. The DS130 does either, at up to 6 litres an hour, set from a text menu.

## Questions and answers

### Why add minerals to UAE water?

Desalinated water, and RO water even more so, is low in minerals. A measured dose of minerals improves taste and suits coffee and some equipment better.

### Is antiscalant needed on Dubai mains?

Not often, as the mains is soft. It is mainly for RO plants running on well or tanker water, where hardness is much higher.

### Can it dose in proportion to flow?

Yes. The DS130-P40 version comes with a DN 40 pulse water meter, so the dose follows the actual flow.
