10 tips for purification W
hether in a laboratory or hospital, an effective water purification system should not
only be reliable, cost effective and energy efficient; it should also be capable of meeting the needs of every application. Here, Triple Red offers its top tips for ensuring safe water systems in medical environments.
1. A question of application The purity of water required for a laboratory or hospital will be highly dependent on the applications it will be used for. Ensure you carry out a full audit of all potential users and the specifics of each application involved.
2. Volume and frequency The application audit should be both detailed and quantitative to enable annual volumes by water type to be calculated as accurately as possible. It should include usage frequency to
ensure final system design accommodates the highest levels of demand, while minimising the need to store water
3. Know your space The amount of space needed to accommodate a fit-for-purpose system can be minimised if part, or all, of the system components can be safely and securely wall mounted or installed on the bench-top or as a built-in system. Plus, the pure water dispensing point
must be accessible to all users and all components must offer easy access to allow for maintenance.

4. Correct pre-treatment The quality of pure water is highly dependent on the quality of local feed water. It is, therefore, essential to test and understand the specifics relating to the chemical and physical impurities associated with available raw water and ensure the correct pre-treatment is included in the system design.
5. Data capture Monitoring and recording key performance indicators associated with water production should be done on a regular basis. A system plan should ensure all necessary data will be captured and recorded in a useful format.
6. Suitable storage The majority of pure water systems require a suitably-sized storage reservoir. This should have appropriate level controls to control filling of the reservoir when required and a hydrophobic 0.2µm air vent filter. It should also be manufactured from an inert material which does not react with the pure water and have a conical base to allow total removal of contents when cleaning.
7. Tracking consumables It is essential that consumables such as ion exchange cartridges, pre-treatment filters and UV lights are replaced on the recommended timescales to maintain optimum quality of the water. It is also recommended that a stock of critical spare parts is held on site.
8. Energy consumption It is possible for manufacturers to supply information on how much energy a water purification system will consume during use. A simpler method to manage energy consumption is to select systems that can go into standby mode, turning off UV lights and other components when not required.
9. Consider the environment Water purification systems vary enormously in efficiency, so evaluate feed water quality for a period of time to allow system designers to optimise system performance, and design and size the system to suit water purification needs, using the lowest appropriate level of water quality for each application.
10. Quality assurance For quality assurance, it’s important to check that the pure water system you choose is designed and manufactured under ISO 9001 certification and that it complies with the local electrical and safety regulations (CE, IECEE, UL, EMC & FCC)
