Sludge thickening and dewatering equipment rebuilds

Restore and improve decanter centrifuge and belt press performance — for less than the cost of capital equipment

If the reliability and performance of your dewatering and thickening equipment have become less than optimal over the years, it may be time to consider an equipment rebuild. Rebuilding or upgrading equipment can save a wastewater treatment plant significant costs by avoiding expensive engineering or structural expenditures associated with new equipment. With decades of expertise, Alfa Laval can restore your decanter centrifuge, gravity belt thickener or belt filter press to original, or better, performance. New technology may also be able to be retrofit to older equipment, boosting performance or improving efficiency.

Whether you’re looking to increase capacity, improve cake dryness, reduce maintenance costs and more, trust Alfa Laval to deliver the process results you need.
