Through periodic working during a longer stop of the plant (night/weekend) a germination of the individual components is prevented. With this measure a inadmissible temperature rise in the dynamic working pure water system is prevented. The most important pure water values are shown on the central monitoring system. Sterilization with ozone In order to prevent germinating, electrolytic produced ozone is used. The electrolytic ozone generator works after a single adjustment fully automatic. Individual Components: Pendulum softening plant For softening flows the water through the ion exchange resin, which binds the calcium and magnesium. Is the resin satisfied with calcium and magnesium it is regenerated with a salt solution and afterwards rinsed. The softener is equipped with two resin pressure bottles, which are in change softening the water and are being regenerated: Pendulum softener. Through short regeneration intervals, silver resin additive (0.5 %) and time and volume steered regeneration release the germs count in the softened water is kept down. To kill all remaining germs in the softened water a UV- sterilization plant is connected afterwards. Before the reverse osmosis plant is a 5 µm filter. Christ K of 5

2 Reverse osmosis plant In the first reverse osmosis step the pressure on the before treated water is taken up to about 18 bar and the water is about 97 % salt free. The salt containing concentrate is rejected. Before the second reverse osmosis step, To the permeate (pure water: conductance about 5 µs/cm) is given caustic soda solution in proportion to quantity. The caustic soda solution binds free carbonic acid, which is hold back as bicarbonate by the reverse osmosis membrane. Additionally this alkalization leads to a better hold back of organica. In the second stage the remaining solved materials are practically completely removed. Because the concentrate of the second stage is already more purely than the softened water it is returned to the first reverse osmosis step. Through that the entire pure water yield of the plant improves about 80 %. The special pharma design of the reverse osmosis plant leads to a bacteriological perfect pure water quality. Storage and Distribution The permeate of the second reverse osmosis step is stored in two stainless steel storage tanks with a capacity of 1,5 m2 each. Two independent working distribution systems lead the treated pure water to the consumption stations. Pure water distributions system storage tank 1 This distribution system serves as supply for the fabrication groups. The pure water is led with a circulation pump over a ring pipeline system with a UV plant (destroys the ozone) to the consumptionstations. To prevent germination of the ring pipe line system and the storage tank, the return water is ozonized with a electrolytic ozone generator. To fully degrade the ozone before the extraction points, special UV- plants are installed. As a autonomous consumption station a 150 liter warm water tank ( storage tank 3 ) is connected to the ring pipe line system. The warm water tank supplies cleaning plant. The tank is step less heat able up to 90 C through a steam heater. The water is pumped with a circulation pump through the ring pipe line to the consumption stations. Storage tank 2 Pure water is supplied in second priority to the storage tank 2. The tank supplies different consumer (z. B. Laboratories). The tank system is build to prevent any water mixture from tank 1 and tank 2. From tank 2 the water is fed in the branch line net through a booster pump with over stream. Likewise electrolytic generated ozone keeps the contents of tank 2 germ free. All data are without guarantee Christ K of 5
