Is my water clean enough or will it harm my plants? The question is simple, the answer is not. One of the most common methods of water treatment is physical screening. Typical physical filters include sand, mesh screen, disc, glass, or other substrates that serve as barriers to particulates. During physical screening, the materials in the filter serve as a barrier to stop particles (sediment) from moving through the filter. Learn more about these filters, and how to keep your plants safe from disease and chemicals that may be spread through recycled irrigation water.

Typically, the first step in irrigation water treatment is physical removal of larger particles such as sediment, substrate material and organic matter. But rapid sand, mesh filters, etc. are not able to remove biological contaminants such plant diseases. Chemical disinfection is a safe and effective way to ensure removal of plant disease organisms from irrigation water. Chemical treatment efficacy declines if high levels of organic matter are present in water, making it necessary to increase the concentrations of chemicals needed to treat the same volume of water.
