How a Disc Filter Works

An irrigation disc filter is a type of filtration device that uses a stack of plastic discs to remove debris and sediment from your sprinkler system. Each of these discs has tiny grooves that, when stacked together, form a network of microscopic pathways. Particles such as sand, dirt, and algae become trapped within the disc stack, while clean water continues through the system. Typically, the degree of filtration depends on how fine the grooves are, which can be selected based on the water quality and irrigation needs.

Disc Filter FAQs

How do you clean a disc filter?

After shutting off the system, open the filter by unscrewing the cover or clamp. Inside, you’ll find a stack of discs. Separate the discs and rinse them thoroughly with clean water to remove trapped debris. You can also scrub them gently if you need to dislodge any stubborn particles. Once the discs are clean, you can reassemble them in the correct order, secure them inside the filter housing, and restart the system. Make sure to check for leaks or drops in water pressure once the process is complete.

How long do disc filters last?

Disc filters are built to be rather durable and can last up to 5 or 10 years. However, depending on factors like water quality, usage frequency, and how well you maintain the filter itself, this timeline can change. Regular cleaning may extend the disc filter system’s lifetime, but eventually, the discs may become worn and less effective at trapping particles. Try to inspect the discs periodically for signs of damage and replace individual components as needed.

What is the difference between a disc filter and a screen filter?

The main difference between a disc filter and a screen filter lies in their filtration mechanisms and how they handle debris. A screen filter uses a fine mesh screen to physically block particles as water passes through it. Meanwhile, disc filtration systems use a stack of grooved plastic discs that create a three-dimensional filtration path, capturing particles throughout the depth of the disc stack. Disc filters for drip irrigation can therefore handle higher levels of sediment without clogging as quickly.
