Car Wash Water Filtration Systems

Protect pumps, nozzles, and reclaim systems from grit, sand, and debris.

Car wash water filtration removes grit, sand, and suspended solids from wash and reclaim water so pumps, spray nozzles, and reclaim systems keep running at peak demand.

Yardney centrifugal sand separators and screen filters are built for solids removal, with purple reclaim-ready finishes available.

  • Separators from 4 gpm, screens from 110 gpm
  • Purple reclaim-ready finish available
  • Automatic or manual cleaning options
  • Serving industry since 1965

Why Car Washes Need Filtration

Car washes rely on consistent flow and clean water to protect pumps, spray nozzles, and reclaim systems from grit, sand, and debris. Reclaim water that carries sediment can clog nozzles and wear pumps, so it needs to be filtered before it is reused.

Removing suspended solids early supports clearer wash quality, reduces nozzle plugging and equipment wear, and improves reuse performance. That helps operators reduce water consumption and keep systems running smoothly during peak demand.

Benefits

Reduce Nozzle Plugging: Remove grit and debris that clog spray nozzles.

Protect Pumps: Reduce the sand and sediment that wear down pumps.

Improve Reuse Performance: Cleaner reclaim water supports more reuse and helps reduce water consumption.

Support Clearer Wash Quality: Keep solids out of the water that reaches vehicles.

Yardney Maxi-Clean Screen Filters

Maxi-Clean screen filters are designed for high-performance solids removal where durability and economy matter. Their large screen area produces less than 2 psi pressure drop, with long run times between cleanings.

Filter socks are field changeable, washable, and replaceable in 40, 80, 100, 150, and 200 mesh, filtering down to 75 microns. Housings are available in purple for reclaim water applications.

Applications

  • Car wash reclaim and wash-water systems
  • Removal of sand, rock, grit, and other inorganic contaminants
  • Protection of pumps and spray nozzles
  • Primary filtration, or secondary filtration after a sand media filter or centrifugal separator
  • Reclaim water applications (purple finish available)

Standard Assembly Includes

  • Carbon steel housing
  • Interior epoxy coating (3M Scotchkote 134)
  • Polyester powder-coated exterior
  • Internal cartridge element with field-replaceable filter mesh
  • 3-way ball valve and pressure gauge
  • Purge valve for manual flushing

Available Options

  • ASME code
  • High-pressure rating
  • Grooved or flanged mainline connections
  • Purple finish for reclaim water applications

Car Wash Water Filtration Process

  • Wash or reclaim water is routed through a separator or screen filter ahead of the pumps and nozzles it protects.
  • Heavy sand and grit are separated out, and remaining solids are captured on the filter screen.
  • Filtered water returns to the wash or reclaim system.
  • Separators purge solids manually or with an automatic flush valve, Maxi-Clean filters are flushed manually through a purge valve, and Maxi Flush filters backwash automatically.

Filtration removes suspended solids. It does not remove dissolved chemicals, so reclaim water quality may still depend on other treatment.

Filtration Technology Options

Centrifugal Sand Separator: solids with a specific gravity of 2 or greater, 98% down to 75 microns; manual or automatic purge; flows from 4 gpm

Maxi-Clean Screen: down to 75 microns, 40 to 200 mesh filter socks, flows from 110 gpm, manual flush

Maxi Flush Screen: down to 75 microns, 40 to 200 mesh cartridges, flows from 250 gpm, automatic backwash

Car Washes Filtration FAQs

Why filter car wash reclaim water?

Reclaim water that carries sediment can clog nozzles and wear pumps. Filtering out suspended solids protects that equipment and improves how well reclaimed water can be reused.

Grit, sand, and debris are the main culprits. They plug spray nozzles, wear pumps, and reduce reclaim system performance.

Centrifugal sand separators remove heavy sand and grit, and Maxi-Clean and Maxi Flush screens filter down to 75 microns. Separators start at 4 gpm, Maxi-Clean at 110 gpm, and Maxi Flush at 250 gpm.

Yes. Maxi-Clean, Maxi Flush, and basket strainer housings are available in purple for reclaim water applications.

Removing solids early improves reuse performance, which can help operators reduce water consumption. Results depend on your wash system and reclaim setup.
