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

If your belt filter press or gravity belt thickener is showing signs of reduced performance due to wear and tear or changing process conditions, it may be time to consider a rebuild. Refurbishing or upgrading your equipment 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. 

The rebuilds process can also be up to 30% less expensive than purchasing new equipment. 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.
