Gravity belt thickener and belt filter press  rebuilds and upgrades

Restore and improve gravity belt thickener or belt filter press performance for sludge dewatering and thickening


Refurbishing or upgrading your gravity belt thickener or belt filter press can restore, or even improve, sludge thickening or dewatering performance – improvements of 2-3% solids increase are typical. With decades of expertise in the industry, Alfa Laval can restore equipment to factory OEM specifications – no matter the brand. All rebuilds are backed by a warranty. 

By avoiding expensive engineering or structural expenditures associated with new equipment, you can significantly save time and money while ensuring that you continue to get the process results you need.

Upgrade options for belt filter presses and gravity belt thickeners

Rooted in the Ashbrook Simon-Hartley history, and growing into the newly developed AS-H KPZ belt presses, the deep knowledge and technology portfolio at Alfa Laval allows for many older machines to receive modern upgrades that can dramatically improve performance and efficiency.

While each machine will have different options available depending on its design, some examples of the possibilities include:

  • Increase pressure section rollers to improve sludge cake dryness
  • Extending the gravity deck to create more drainage prior to the pressure rollers
  • Enhanced control systems to allow better control and automation of the equipment
  • Full control panel rebuilds, bringing them up to modern day standards and capabilities
  • Upgrading chicanes (plows) to modern design to increase turbulence and water removal on the gravity section
  • Modify bearing enclosures to reduce contamination possibility
  • Upgrade hydraulic unit to allow for easier maintenance and smaller oil reservoirs
  • Improve wash boxes to allow for greater accessibility and maintenance access
  • Reduce maintenance by upgrading to shaft mount drives
