Microbial Technology

Bell, N., Majsztrik, J., and S. White (Clemson University)

Ecological treatment methods such as slow sand filters, bioreactors, and algal turf scrubbers are low-cost, low energy technologies which harness the power of naturally-occurring microorganisms to remediate nutrients, agrichemicals, and pathogens in water.  System costs are substantially lower than chemical disinfestation and remediation technologies.  European horticultural growers have been using slow sand filters (SSFs) since the early 1990s, however SSFs have been used since the early 1800s to clean contaminants from water for human consumption. Recent research has shown that slow filters containing pumice and rockwool are able to effectively remediate pesticides and nutrients from irrigation water.

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.
