Soaking Requirements
When new GAC is added to the system, it is dry, and the external void space and internal pore spaces are filled with air. The GAC material only occupies 20% of the bed volume; the remainder is air. The internal GAC pores are approximately 40% of the GAC bed volume. Soaking allows the water to diffuse into the pores and displace the entrained air. Because GAC surfaces are hydrophobic, it takes a reasonably long time to wet the carbon pores and displace the air. The amount of time required is a function of temperature and carbon mesh size. Higher temperatures allow for faster diffusion; conversely, larger particles have longer pores and require more time for diffusion.

Hello RAMPS Community,
Spring has sprung! Our efforts over the winter to find new funding for projects are proving to be fruitful; we have three new projects on the horizon. These projects demonstrate the importance of diverse science to support land management. The projects span interdisciplinary socioecological research to u
