Questions: The processes at Orange County almost other plants than clean the water include microfiltration that strains out anything larger than 0.2 microns, removing almost all suspended solids, bacteria and protozoa. This process at Orange County and most other plants then clean the water include microfiltration that strains out anything larger than 0.2 microns, removing almost all suspended solids, bacteria and protozoa. "A zap with powerful ultraviolet light and a bit of hydrogen peroxide finishes the job," he said. "But after all that, 13 percent of the water say they would also use to be recycled into the purified water, according to recent study in the journal Environmental and Resource Economics." "A small minority of people are very offended by this and can't get it down or stop it because of psychological barriers," said the study's lead author.

The excerpt from "Water Flowing from Table to Swallow's" describes the water purification process used at Orange County and other similar plants. Here is a breakdown of the key points:

1. Microfiltration: This process involves straining out particles larger than 0.2 microns, effectively removing almost all suspended solids, bacteria, and protozoa from the water.

2. Ultraviolet Light and Hydrogen Peroxide: After microfiltration, the water is treated with powerful ultraviolet light and a bit of hydrogen peroxide to complete the purification process.

3. Public Perception: Despite the thorough purification process, a study published in the journal Environmental and Resource Economics found that only 13 percent of people are willing to use recycled water that has been purified. The study's lead author notes that a small minority of people have strong psychological barriers that prevent them from accepting recycled water.

In summary, the excerpt highlights the advanced techniques used to purify water and the challenges in public acceptance of recycled water due to psychological barriers.
