Sand media filters are one of the most effective filtration technologies for removing algae from irrigation water, lakes, ponds, reservoirs, and decorative water features because they utilize depth filtration rather than simple surface screening.

Canal water is one of the most challenging irrigation water sources because it often contains sand, silt, algae, aquatic weeds, organic matter, and seasonal debris loads. The best filtration technology depends on the type and amount of contaminants present.

Well water is generally cleaner than canal, pond, or surface water, but it often contains sand, grit, scale, iron, manganese, and other inorganic particles that can damage irrigation equipment or clog emitters. The most common filtration systems are selected based on the specific contaminants present in the well.
