Field guide
Guide to disc filters
Disc filters trap particles in a stack of grooved discs and can be cleaned according to the product's procedure. This diagram shelf links the listed disc filter for irrigation models, which differ in body shape and connection size.
Choose a filtration rating for the smallest downstream outlet, then compare operating flow, pressure loss, maximum pressure and cleaning access. Check the source water and any sand-separation step; a disc element may clog rapidly when asked to handle heavy grit alone.
Where and when to use it
A disc filter for irrigation protects small downstream passages where its rating and flow match the water source. The diagram route has a limited set of related products. Position it where an operator can remove or backwash the element and measure pressure loss. A compact filter that fits the pipe may still be too small for the combined zone flow.
How it works
A stack of grooved discs creates a particle-retaining flow path. Solids accumulate and increase differential pressure until the element is cleaned. Disc filters have different ratings and cleaning methods, including manual removal and automatic backwash. Filtration grade should follow emitter recommendations and real water quality, not an arbitrary color or label.
A drip irrigation disc filter traps particles between grooved discs and requires periodic cleaning as the pressure difference rises. Match the model's rated flow and filtration grade to the selected emitters and leave room to remove the cartridge.
How to plan and install it
- Check water source, outlet sensitivity and required filtration grade.
- Select a model rated for operating flow, pressure and connection size.
- Install in the correct direction with access to isolate, drain and read pressure.
- Flush the supply first and record pressure across the clean filter at normal flow.
Operation and maintenance
Clean when the permitted pressure loss is reached, inspect seals and reassemble the disc stack correctly. Retest pressure after cleaning. If disc filter irrigation performance degrades rapidly, investigate incoming solids or an undersized unit rather than repeatedly increasing pump pressure.
Common questions
How do I clean a disc filter?
Isolate and depressurize it, then follow the model's disc-removal or backwash procedure and inspect seals before restart.
How do I pick a disc filter for irrigation?
Match required particle retention, real zone flow, allowed pressure loss and cleaning capacity.
