Dune
Dry smarter, store smaller, spend less – Dune is a game changer in biosolids drying
Dune is a smarter way to dry wastewater sludge. This innovative patented technology uses 90% less energy than traditional drying methods and reduces biosolids volume and mass by more than half.
Dune transforms biosolids cake into a dense, soil-like material that’s easier to handle and cheaper to manage through thermal treatment or land application. The benefits include lower transport and disposal costs, reduced emissions and a smaller storage footprint – all while using less power.
As biosolids management faces growing pressures, such as increased disposal costs and land application limitations, Dune provides wastewater utilities with a more effective way to manage wastewater sludge. It benefits all end uses including land application, thermal treatment, landfill and land restoration.
Key Dune benefits
60 kWh per ton of water removed – about 90% less energy than traditional drying methods.
Cuts biosolids cake by more than 50% (based on 30% dry solids input).
Compatible with a wide range of biosolids reuse and disposal options.
Minimal installation and maintenance expenses.
Dune by the numbers
water removed from dewatered sludge cake
dry solid output
less energy used than conventional drying
storage capacity because of reduced volume and improved stackability
