Berlie - Low Temperature Belt Dryer- Brochure

The Bristol Waste Water Treatment Works in Avonmouth, UK, operates since 2008 a belt dryer evaporating approximately 3 tons of water per hour heated with steam that is heated by exhaust gases from generators. The sludge to be dried comes from an advanced anaerobic digestion and its biogas is used in the generators to make electricity. The final dried product is broken down to desired sizes to be used as a Class A fertilizer.
