For the manufacture of a small medical items such as wound dressings, catheters, syringes, scalpels, artificial joints and many more similar devices, pure water is essential to keep the device clean, contaminant free and without bacterial deposits before they are hygienically packed for use.

Due to the specialist nature of this industry, it often deionised (DI) quality water that is used as all ions and salts have been removed, leaving no surface imperfections. This water is then commonly passed through a bacteria removal filtration stage to avoid bacterial contamination.

Stages of Filtration & Water Treatment

Sediment Removal

Prevents debris, scale flakes, dirt and particle build up in pipework, tanks, equipment and where present, premature blinding of filtration stages further along the cascade.

Chlorine and Organics Removal

Helps the taste and odour of the liquid and where present, protects RO membranes from chemical attack.

RO Quality Water

Very pure water is produced using reverse osmosis membranes to separate the majority of salts and ions from the feed water and sending the salts and ions to waste or re-circulation.

The use of a mixed-bed resin of anion and cation, attracts all salts and ions, removing them from the water.
