Mesh and Disc water filters

Industrial Disc filter and mesh water filters are designed to retain suspended solids in water, such as sedimentation, with great savings in water consumption and space, in commercial and industrial applications. If you need to filter water at high flow rates, a ring or mesh filter is the best choice.

One of the types of industrial water filters is the disc filter, which is an equipment whose objective is to retain suspended solids. It was born as a proposal to filter irrigation water, and gradually found applications in all areas that use water.

It can be said that it started from the basket type filters, in which the filtering media is a metallic mesh. In the process of innovation, this medium evolved into independent plastic rings (discs) that are applied one on top of the other.

Water mesh filter. What is it?

An automatic self-cleaning screen filter is a high efficiency water filter that removes suspended solids from contaminated water sources. Screen filter technology was born in the early 20th century when it was invented by an Irish engineer named Thomas A. O’Brien. The first automatic screen filter was called the “O’Brien Screen” and was patented on November 9, 1913. This technology has been improved to become what we know today as an automatic self-cleaning screen filter for flow rates from 10 to 1500 microns for full contact.

Applications of ring and screen filters:

Ring and screen filters are used in a wide variety of applications:

  1. Wastewater treatment plants.
  2. Clarification and removal of grit or sand.
  3. The use of such a filter is also beneficial for the removal of suspended solids from contaminated water sources.
  4. Cooling tower water.
  5. High flow municipal water.
  6. Food and beverage processes.
  7. Chemical industry.
  8. Pharmaceutical industry.
  9. Industrial waste filtration.

Main benefits of disc water filters:

  • Fewer moving parts: resulting in less need for maintenance.
  • Fast backwashing: Disc filters can be backwashed in much less time than sand filters.
  • Low water waste: The advantage of durability translates into saving hundreds of gallons of water.
  • Space savings: The disc filter system requires approximately 1/3 of the space of a sand filter system.
  • Less maintenance: The sand must be replaced periodically, and if the sand filter is abused and not backwashed regularly, the sand will require replacement quickly. Disc filters last many years without requiring replacement because the plastic discs are highly resistant to deposits.
  • Less pressure required: Disc filters require less pressure for backwashing than sand filters. This may allow the use of a smaller supply pump.
  • Efficient backwashing: The lack of backwashing a disc filter will lead to low water flow, but when disc packs are backwashed they are immediately cleaned and easily restored to service.
  • Rapid capacity increase: Filtration capacities can be changed quickly by simply changing the disc pack to the size at which filtration is desired.
