"Chemical Affinity is the attractive force between substances that causes them to enter into or remain in chemical combination."

ApHinity from EAI is a brand of technologies based on the science of chemical affinity. Targeted ion exchange, radial deionization, and natural low-pressure osmosis technologies are scientific examples of chemical affinity. Each respective technology leverages the natural chemical affinity for substances to either enter into, remain in, or separate from chemical combination. These technologies play a critical role in the challenging water conservation, reuse, and recycling environments of today.
