Used Disc Filters in California, USA

Overview

Disc filters are modular filtration units that use stacked, grooved discs to remove suspended solids from liquids. Common in irrigation, industrial water treatment, aquaculture and cooling systems, they offer high flow capacity, fine filtration ratings and easy backflushing or manual cleaning. Disc filters handle variable loads and are valued for compact footprint, simple maintenance and scalable capacity using additional disc packs or multiple units.

FAQ

What should I check when buying a used disc filter?

Verify filtration rating (microns), number and condition of discs, housing integrity, drive motor and valves, seals and bearings. Confirm flow and pressure specs match your system, request maintenance records and, if possible, a test run.

How do I prepare a disc filter for shipping?

Drain and thoroughly clean the unit, secure or remove fragile parts, lock rotating components, pad and crate the housing, and label weight/dimensions. Use a carrier experienced with industrial equipment and provide handling instructions.

What routine maintenance does a disc filter need?

Regularly inspect and clean discs, check seals and O-rings, service valves and motors, and monitor pressure differential. Replace worn discs or gaskets and keep spare sealing parts on hand. Frequency depends on water quality and operating hours.
