Patient Feed

The water through a dental chair is required to be bacteria free, ready for use by patients to rinse out their mouths, or by dentists during procedures. Dentist chair lines are prone to a build-up of deposits due to thin connections and circulating water, which leads to bacteria growth that risks patient contamination. Deposit build up can also cause damage to apparatus, reducing it’s the service life and making equipment, such as drills, unsafe to use.

In light of this, ultra-pure water is required for the patient feed to ensure there is no particle build up or bacteria exposure. To purify water to this level, particulates and organics need to be removed from the water before the reverse osmosis stage. This will enhance the filtration by removing ~99% of bacteria, ions and dissolved solids from the water. A polishing stage is then required that uses deionisation resin to remove all ions and salts, before directing the water through a final Ultraviolet sterilisation system to kill any remaining bacteria and inhibiting its future growth.

 

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.
