Getinge Water Treatment

The lifetime of sterilization and disinfection equipment, as well as the general hygiene of your facility, can be greatly affected by the quality of the water you use. Getinge offers a selection of highly effective and cost-efficient water purifiers, filters and softners to solve such water problems.

What is �clean� water?

There is no single answer, as each application has its own specifications. Each batch of water has its own unique composition and contains various salts, metals, impurities and relative volatility. The question should be �What degree of purity is required for what application?�

In sterilization and disinfection, the purity of the incoming water can make a big difference in the overall operating economy of your equipment – and even in the quality of the results! In a sterilizer, water moves from the liquid phase to the steam phase, other substances are concentrated and precipitate, causing breakdowns, higher operating costs, and in the worst cases contaminated steam.

The solution to these problems is to feed the sterilizer with water that has been purified from salts, metals and impurities. An excellent, cost-effective way to achieve this purification is by means of reverse osmosis (RO), which separates the incoming water into “clean” water and reject water via a reverse osmosis membrane. The RO-water is > 99% pure water with no additional components. The reverse osmosis membrane is sensitive to free chlorine, excessive hardness, metals, organic and inorganic compounds. To assure the good operating economy and high availability of the reverse osmosis unit, the feed water must be pretreated.

Free chlorine is reduced by means of an active carbon filter. Water hardness salts are reduced with a water-softening filter (Princess Midi E). If there are water hardness salts and iron in the water, a Princess Turbo-E watersoftening filter should be used.

Water treatment selection guide

In order to receive feed water and condensate in accordance with EN-285, a general selection guide is presented below.

It is important to note that this is a general guide. Raw water quality must be verified by water analysis in accordance with EN285, free chlorine content.

1. RECIEVE FEED WATER IN ACCORD ANCE WITH EN -285

To receive feed water (RO-water) for steam generators, RO-51 may be used (degassing tank needed).

2. PRE-TREATMENT FOR REVERSE OSMOSIS

To obtain optimal working conditions and economical service on the RO-51 unit, pre-treatment of incoming water is recommended.
