Slow Sand Filters
Pitton, B.J.L., Oki, L.R. (University of California Davis), White, S.A (Clemson University)
Slow sand filters (SSF) can provide high-quality water from untreated sources like irrigation runoff. SSFs consist of a sand bed with about three feet of water above that flows through the sand via gravity. A microorganism community develops on the sand that has the ability to remove plant pathogens, including water molds, viruses, bacteria, and fungi. Flow rates are approximately six inches per hour so they can occupy a large area if sizable volumes of water need to be treated. However, SSFs are simple to install and are fairly cheap to operate compared to other treatment technologies.

Plants With Purpose
Garcia-Chance, L., Majsztrik, J., and S. White (Clemson University)
Bioremediation, which is the process of using plants and microbes to remove contaminants from water and soil, has been used successfully in many different forms. Ornamental growers can use plants to effectively treat irrigation water. These systems are able to remove nutrients, sediment, and other contaminants from water before it is reused of runs off site. There are a number of different ways that bioremediation can be used at ornamental operations including installing floating mats on irrigation ponds which can save space, provide additional revenue, and reduce algae growth.

Water Quality Quest
Majsztrik, J. and Sarah A. White (Clemson University)
Is my water clean enough or will it harm my plants? The question is simple the answer is not. Activated carbon and membrane filters are tools worth considering if you recycle water or have problems with water quality. If you recycle water, routinely spray PGRs, or non-target crops at your operation are stunted or deformed, you may have residual chemicals in your recycled water that could be reducing plant quality and thus hurting your bottom line. Learn more about these filters, and how to keep your plants safe from disease and chemicals that may be spread through recycled irrigation water.
