2 Series RO S A convincing performance: Multi-purpose purity the reverse osmosis equipment RO...S and RO...SMB series Typical applications Series RO...S Feed for ultrapure water systems, general chemistry, laboratory washing machines, water for autoclaves and environmental chambers, buffer preparation Laboratory, medical and industrial applications all need pure water in various qualities and quantities. The RO... series produces pure water for a wide variety of applications by reversing the natural osmosis process to deionize water in an environmentally friendly manner. Pure water produced via reverse osmosis can be put to a number of uses in laboratories for Flowsheet RO...S switch gauge Pump rinsing laboratory glass ware or as feed water to autoclaves, climatized cabinets and ultrapure water systems. The RO series focuses on economic efficiency, combining a compact design with highquality components and intelligent controls. The quality of the pure water produced depends on the quality of the inlet water entering the system. RO-Module The reverse osmosis RO...S series is designed to produce large amounts of purified water with conductivity values depending on the salt content of the feed water (for example 1000 µs/cm tap water quality: < 20 µs/cm product water). The deionizaton rate is at least 98 %. Additional equipment, such as different tank sizes and pressure pumps, can be added to the plant according to customers individual needs. The system can, for instance, be set up as a central water treatment plant within a building and supplemented with accessories to form a closed circuit pipeline. All systems are equipped with an RS 232 interface. We would be happy to advise you!

3 Typical applications Series RO SMB Series RO...SMB Feed for ultrapure water systems, general chemistry, laboratory washing machines including final rinse, water for autoclaves and environmental chambers, buffer preparation, photometry, spectrophotometry, media preparation The RO...SMB series incorporates RO membranes and mixed-bed cartridges to produce pure water with conductivity values under 0.1 µs/cm. The reverse osmosis membrane is the initial deionization component, leaving the mixed-bed ion exchanger to deal with post-deionizaton. This reduces the cartridge exchange frequency and, in turn, the operating costs. We have integrated a completely dischargeable storage tank and a pressure booster pump. This system can also be operated as a central water treatment facility in, for instance, a laboratory wing with a closed circuit pipeline. Additional integration options include UVoxidization and disinfection, CO 2 traps for the tank, sterile filtration and ultrafiltration. All units are supplied ready for immediate use, with all equipment installed into a cabinet and fitted with an RS 232 interface.

4 Information pure water The principle behind El-Ion electro-deionization Our electro-deionization process utilizes resin chambers in a single bed configuration to further deionize the water. Microbiological analysis has proven a remarkable reduction in the number of bacteria with high CFU counts in the feed water. The electrodes that contact the resin create an electric potential in the water that is unsuitable for bacteria to live in. The intermediate ph shift in the cells creates a positive effect for the removal of SiO 2 and CO 2 and helps as well to reduce bacterial growth. An other advantage of electro-deionization is continuous operation. The resin is continually regenerated without the use of any chemicals. The energy consumption of this process is very low and serves as an advantage for the environment. No chemicals and low power consumption. The principle of the El-Ion cell system outlet [µs/cm] 100,00 10,00 The most convincing advantage of the RO...plus series is the integrated deionization El-Ion cell. Comparison Ix-Resin / Electro-deionization El-Ion 1,00 0,10 0, Time in days Ix-resin El-Ion When a mixed bed polishing module is used, the conductivity of the product water increases during normal operation. The resin has to be changed or regenerated if the maximum acceptable conductivity is reached. If using El-Ion electro-deionization, the product water quality is constantly at the highest level. No regeneration, no quality variation. Simply high quality water at any time. raw water / dissolved salts 100% cation exchange membrane anion exchange membrane concentrate salts H O 2 + H + SO 2 Ca 2+ 4 Mg 2+ HCO 3 O 2 Cl OH H 2 semipermeable membrane cation exchange chamber Na + CO 2 3 HSiO 3 anion exchange chamber pure water / permeate dissolved salts 1 2 % + H drain OH concentrate chamber conductivity: 2 30 µs/cm ultra pure water: µs/cm 4

5 Series RO plus A highly perfected technology reverse osmosis incl. El-Ion electro-deionization Consistently high water quality without the use of chemicals The combination of RO...S with the El-Ion electro-deionization cell significantly improves the quality of the pure water. The RO...plus units are available with either a singlestage or a two-stage El-Ion electrodeionization cell. Our systems are distinguished by their ability to produce a consistent level of pure water quality, reaching conductivity values less than 0.1 µs/cm in singlestage plant and below 0.07 µs/cm in two-stage plant. Typical applications All types Feed for ultrapure water systems, general chemistry, laboratory washing machines including final rinse, feed for autoclaves and environmental chambers, buffer preparation, photometry, spectrophotometry, general chemical analysis, media preparation, protein electrophoreses, microbiological media preparation, cytology and histology work, electrophoreses The design of RO...plus equipment is timeless and practical. Pure water is produced in highest quality at rates of between 120 and 750 l/h.

6 Series RO plus Flowsheet RO plus switch gauge RO-Module Flushing port Pump El-Ion cell Flow meter Restrictor Pre-Filter control Service Restrictor The TOC content is less than 30 ppb. The special layout of the separate bed process and the associated shift in ph value towards the acidic reduces the bacterial count and prevents bacterial growth in the cell. No other system works more efficiently or more economically, as the El-Ion cell only has a 10 % loss rate. This is a particularly inexpensive system in terms of operating costs, and maintenance is minimal. And the compact cabinet design means that our system is at home in the smallest of spaces. All plant is equipped with an RS 232 interface. The side panels are easy to remove from all RO...plus cabinets. This makes it very easy to access the equipment inside (equipment photographed without front and side panels). 6
