The purpose of water purification systems is to remove contaminants from tap water, including inorganic ions, organics, colloids, gases, bacteria, and proteases to ensure the accuracy of experimental results. Depending on your applications and the space you have in your lab, there are many different filtration types, water purification techniques, and system configurations that could work best.

6 Questions to Ask When a Water Purification System:

  1. What level of purification do you need?
  2. How much water will you require at one time?
  3. How often do filters and cartridges need to be replaced?
  4. How long does it take for the unit to purify the water?
  5. Where will the system be located, and do you have enough space?
  6. Can the system be expanded if demand increases?

Reverse Osmosis vs Deionized Water Purification

Reverse osmosis water purification is an inexpensive method for general purpose or prefiltering water before feeding it into a higher-purity filtration system, such as deionization systems.

Should I Repair or Replace My Purification System?

In general, it’s best to replace equipment when its maintenance and repair costs approach the cost of buying a new unit. Other factors to weigh might be regulatory influences, the system no longer producing the grade of water purification needed, and the frequency with which the purifier is used.
