EZ Clean family of filtration systems

The ZGF EZ Clean filtration systems (Phoenix and EC Series) are the most advanced, best in class, automatic, non-disposable liquid filtration systems.

The EZ Clean family of filtration systems includes the following models.

  • Phoenix
    • Pneumatic Phoenix
    • Electro-Pneumatic Phoenix
    • Electric Phoenix
  • EC100
  • EC700
  • EC700S / EC700SLT
  • EC900

All EZ Clean filtration systems utilize the ZGF Spring Filter element. The ZGF Spring Filter element sets the standard for permanent media, fully automatic, self-cleaning filters. The absolute gap allows ZGF filter systems to efficiently and effectively capture contaminants from liquids; and the unique continuous coil design allows for complete cleaning of the filter element with each backwash.

2. 500 ppm is typical maximum loading for ZGF EZ Clean filtration systems utilizing the patented ZGF Spring Filter.

ZGF Spring Filter Element

ZGF Spring Filter Element

The ZGF Spring Filter is a 316 stainless-steel coil wound with a variable pitch that allows the filter element to open evenly from top to bottom ensuring that all contaminants are completely removed from the filter element with each backwash.

The Spring Filter is manufactured with precision raised nidges. These nidges create an absolute gap that allow the Spring Filter to capture > 99% of spherical particles larger than the micron rating of the filter.

A normal coil does not open evenly from top to bottom causing inefficient cleaning. The full opening of the Spring Filter allows lodged or wedged particles to be easily removed as the gap is increased. While in backwash, the fluid flowing in the reverse direction causes the coil to shimmer which further enhances the cleaning capability of the backwash process.

The backwash is:

  • Quick: 2 to 4 seconds per Spring Filter
  • Efficient: <0.75% of total feed volume for backwash
  • Effective: 100% cleaning of the Spring Filter with each backwash

The ability of the Spring Filter to open uniformly along its entire length during backwash provides three distinct benefits not achievable by automatic backflushing filters with fixed geometric screens (i.e. wedge wire, etc.). The benefits are as follows:

  • Particles wedged or lodged are quickly released and washed away as the gap is increased / opened.
  • Fluid flowing in the reverse direction causes the coils of the filter element to “shimmer” which further enhances the cleaning process.
  • Fixed gapped filters (i.e. wedge wire, mesh, screens, etc.) do not provide enough backwash fluid to flow through a dirty filter element, particularly at micron ratings less than 100. The ZGF Spring Filter gaps open allowing the fluid necessary for effective filter element cleaning. With the Spring Filter, there are no high-pressure nozzles, scrapers, or motors required for cleaning.

The full opening of the Spring Filter coil allows lodged or wedged particles to be easily removed as the gap is increased. During backwash, the fluid flows in the reverse direction causing the coil to open and shimmer. The shimmering effect further enhances the cleaning capability of the backwash process. Click on the Spring Filter animation to see the basic principle of operation.

ZGF Spring Filter is often compared with disc filter technology. But there is no comparison!

ZGF Spring Filter technology offers many advantages when compared to disc filters.

ZGF Spring Filter technology versus a disc filter

ZGF Spring Filter

Disc Filter

Advantage

316 Stainless Steel

  • More durable – virtually zero maintenance
  • 5-year warranty
  • Consistent filtration – doesn’t wear over time

Plastic

  • Not durable
  • Planned and un-planned maintenance
  • Subject to erosion wear resulting in inconsistent filtration
  • Real and perceived drawbacks of plastic

ZGF Spring Filter

Continuous Coil wound with a variable pitch

  • Opens uniformly and shimmers during backwash to ensure complete removal of debris
  • Returns to clean differential pressure after backwash (100% removal of debris with each backwash)

Individual discs

  • The discs operate independently and are subject to systematic fouling / clogging
  • “Clean” differential pressure increases over time / backwash frequency increases
  • Individual discs can get lost or damaged when removed for cleaning resulting in inconsistent filtration

ZGF Spring Filter

Nidge

  • The “nidge” is a precision bump machined on the top surface of the coil creating the filtration gap.
  • Consistent & reliable performance
  • Particles are kept on the outside of the coil.

Valley

  • The filtration gap is created by a “valley”. This valley or impression cause particles to get trapped thereby reducing the effective filtration and increasing cleaning frequency
  • Filter elements foul and require removal of discs for manual cleaning
  • Depth allows particles to get inside, difficult to remove

ZGF Spring Filter

Maintenance Free

  • The stainless-steel Spring Filter requires virtually zero maintenance

Frequent Maintenance

  • The discs must be removed monthly for manual cleaning
