| - | - **electrokinetic absorption.** This process works as water passes through one outer wrap, which causes the material in the wrap to acquire a positive molecular charge that attracts negative ions of certain pollutants. | + | - **electrokinetic adsorption.** This process works as water passes through one outer wrap, which causes the material in the wrap to acquire a positive molecular charge that attracts negative ions of certain pollutants. |
| - | - **physical absorption**. The carbon itself attracts pollutants. Specially formulated binders used in compressed carbon blocks can avoid masking the surface of the carbon, thereby optimizing its ability to reduce levels of pollutants. | + | - **physical adsorption**.

| - | Filters a usually rated by size of the particles it can remove. Typical ratings are from 50 micron (least effective) to 0.5 micron (most effective). We generally use 5 micron carbon blocks in our systems, because it gives us very effective absorption capabilities in combination with acceptable water flow rates. | + | Filters a usually rated by size of the particles it can remove.
