Filter Backwashing Blowers

— Excellence in Manufacturing —

High-Flow Air for Water Filter Regeneration

Backwashing is essential for maintaining the permeability of sand and media filters in water treatment. These blowers provide the rapid, high-volume air burst required to "scrub" the filter media and dislodge trapped solids. The design focuses on quick-start reliability and the ability to deliver high flow at low to medium pressures.

Water Utility Engineering Heritage

With a thirty-year history, Nantong Rongheng is a trusted name in the water utility sector. Our backwash blowers are engineered with the sincerity and performance required to ensure filter regeneration cycles are efficient and thorough.

Flow Volume High Peak Capacity
Startup Time Short-Duration Ready
Oil Quality 100% Oil-Free Discharge
Valve Interface Compatible with Auto-Cycles

Filtration Process Usage

  • Rapid sand filter backwashing
  • Tertiary media filter cleaning
  • Desalination pre-treatment filters
  • Drinking water plant maintenance

Standard and Protective Materials

We utilize high-grade ductile iron for components subject to the mechanical shock of rapid startups. Internal surfaces are protected against moisture and condensation common in filter galleries.

Backwash Efficiency Factors

  • High volumetric efficiency ensures rapid air delivery during short wash cycles.
  • Oil-free air prevents the fouling of filter media with lubricants.
  • Robust construction handles the thermal stress of intermittent high-flow duty.

Utility-Grade Customization

We provide specialized control panels for automated backwash sequencing and high-capacity silencers to manage noise during high-flow air bursts.

FAQ

  • Q: Is oil-free air required for backwashing?
  • A: Yes, any oil carryover would contaminate the filter media and require expensive chemical cleaning. Our blowers are 100% oil-free.
  • Q: Can the blower be shared between multiple filter cells?
  • A: Yes, the constant-volume nature of our PD blowers allows them to be manifolded to serve several filter units.
