|Water Purification Technologies and Silica Breakthrough|
American Laboratory News April 2002
The presence of silica in ultrapure water has long been recognized as an issue in several areas of research and routine testing. In particular, applications in the microelectronics industry are particularly known for their sensitivity to silica, but instruments such as weatherometers, autoclaves, and clinical analyzers also require silica-free water to avoid instrument defection and erroneous results. Hence, the avoidance of silica in the final purification system should be a basic and primary concern. It is therefore extremely important to have a well-designed pretreatment system to remove the bulk of silica and to avoid silica release. While some pretreatment methods and systems are very efficient in removing silica, others have a low efficacy due to the materials used or to system misuse. The most widely used water purification technologies are deionization (DI), reverse osmosis (RO), and electrodeionization (EDI). Their effect on and pertinence for silica removal are discussed in terms of silica chemistry and behaviour under different conditions in this paper and comparative data is presented for these three purification technologies.
RiOs™ Essential systems are ideal for laboratories needing reliable, constant production of Reverse Osmosis, RO (Type 3) water from potable tap water. RO pure water produced by RiOs™ Essential systems is ideal for non-critical laboratory applications, such as:
- Glassware rinsing
- Water baths
- Feed water for humidifiers, autoclaves, glassware washers, washing machines
- Feed water for ultrapure water systems
Systems are available in 5, 8, 16 or 24 liter models to match the specific volume needs of your laboratory.
RiOs™ Essential water • Intelligent purification
RiOs™ Essential is built on an optimized and efficient purification sequence: Tap water first enters the Progard® pretreatment cartridge which efficiently removes particles & colloids, free chlorine and hardness. Pretreated water passes through the reverse osmosis membrane which removes up to 99% of all ionic & organic contaminants, microorganisms and particles. The benefits of RiOs™ intelligent reverse osmosis are:
- No risk of water shortage, even in winter – intelligent RO adapts its production rate to tap water temperature.
- Continuously, high quality RO permeate – intelligent RO is always working to the best of its ability, discarding primary low-quality permeate, protecting downstream purification technologies.
- Environment conscious, water savings – intelligent RO optimizes the recovery of rejected water and in turn maximizes Progard® lifetime.
The Progard® cartridge incorporates RFID technology. This provides instant visibility on cartridge parameters and also ensures a safe & optimal performance of your system, giving you full traceability.
User friendly & easy maintenance
With intuitive controls that simplify operation, RiOs™Essential is user-friendly, and provides just the information required. A color-coded backlit LCD display clearly shows message importance for system alert and alarm icons. With its small footprint, RiOs™ Essential system enables installation wherever it is convenient in your laboratory — on or under the bench, or on a wall. A single replaceable cartridge allows your system to run smoothly all year long while preserving your budget. Millitrack® e-Solutions provide enhanced data management control, remote access capabilities to the system dashboard, and long-term electronic archiving for your RiOs™Essential.
For full confidence in your RiOs™ Essential system, it is delivered with a Certificate of Calibration for the built-in temperature and resistivity meters, and a Certificate of Conformity ensuring that it has been built and tested fully assembled following internal Standard Operating Procedures. In addition all RiOs™ Essential consumables are delivered with their Certificate of Quality. The manufacturing site is ISO® 9001 v.2000 and ISO® 140001 certified.
