Dilution

A key stage in the distilling of spirits is that of dilution, whereby purified water is used to reduce the strength of the spirit before bottling. The use of pure, demineralised water is essential in ensuring that the quality of the product is not impacted during the distillation process.

If calcium is present in the water used for the dilution process, it can cause irreversible ‘floc’ (or the formation of calcium oxalate crystals) that turn the spirit cloudy. Magnesium ions and iron also both affect the appearance of the spirit, for the former creates haze and the latter can turn the whisky black.

To remove the risk of waste product, salts and ions need to be completely removed from source water. To achieve this, particle and organics filtration prepares water for our reverse osmosis system. Deionisation resin is then used to polish the water to a pure and ready to dilute quality.

Treatment Process

1

Particle Removal

Our cartridges offer outstanding absorption of sediment, dirt, sand and scale flakes to prevent filtration systems from blockage and microorganism growth.

2

Chlorine and Organics Removal

Carbon cartridges are a long established choice for the reduction and removal of chlorine, VOCs and heavy metals whilst reducing water hardness.

3

Reverse Osmosis

Pure water (permeate)  is produced during reverse osmosis by applying pressure to force water through a semi permeable membrane, leaving a majority of the present ions and dissolved solids on the other side to drain as waste (concentrate).

4

Post RO Deionisation

Our performance mixed bed resin is specially designed for deionisation directly after reverse osmosis. It holds a 1 : 1.5 ratio of strong acid cations and strong base anions to attract and remove all ions, salts and dissolved solids.
