Alfa Laval Aftermarket

We are here to help you and identify where your product is in its lifecycle, and we’re ready to provide a replacement recommendation, based on your budget and application needs. And if you haven’t recently replaced your equipment, a lot has changed. We’ll guide you through the latest technologies, and how they might enhance your production process.


  • Alfa Laval has been leading the wastewater decanter market for decades. With a strong focus on operational reliability, separation performance and high customer value, Alfa Laval continues to innovate the business.

Gravity Belt Thickener

  • Using gravity to thicken dilute sludge and slurries, the Alfa Laval AS-H belt thickener is suitable for all municipal or industrial flocculated sludges – particularly those from biological and activated sludge processes. Low energy and polymer consumption and trouble-free operation give important reductions in both cost and hassle for wastewater management.

Belt Press

  • Alfa Laval AS-H belt presses are ideal for efficient dewatering of sludge from municipal and industrial wastewater treatment as well as residuals dewatering from fresh water production facilities. There are several models and multiple configurations of the belt filter press that can be customized for your specific needs.
