191 Picture 52.: Susteren sludge drying facility The drier gives a water evaporation rate of approximately 8.300 kg/h <strong>and</strong> a sludge output of 11.000 kg/hr.. The plant operates 7 days a week <strong>and</strong> 24 hours a day <strong>and</strong> the total material is (> 92 % DS). The drying plant at Susteren works by conveying (7 m 3 /h max). The next step is the heating of the sludge in a boiler before agitating the mixture to breakdown large agglomerations <strong>and</strong> the removal of any metal contaminants. Sludge is then transferred for drying with the help of an oil heat exchanger (max 225 o C). Air is induced by two 85,000 m 3 /h fans through the vat’s bottom lining plates, mixing air through the sludge which has an average depth of 4-5m. This process continues while dust <strong>and</strong> moisture is driven off through the cyclone system which has an air stream performance of 59,000 m 3 /h. The dust <strong>and</strong> air is sent back to the (FD) This gives a 60% secondary mix in the vat. Sludge cooling is aided by the exhaust gas taken from the oil boiler to bring sludge temperature down to below 40 o C.
192 The end product is made into a pellet 0.5-2mm wide with a low moisture content consisting of around 92% suspended solids for ENCI’s needs. Picture 53.: The Susteren vat The Storage capacity of the facility is 280m 3 . There are about one or two deliveries by tanker of the dried sewage sludge to the Maastricht cement factory every week. 10.4.3. The Zeeasterweg Lelystad plant in Netherl<strong>and</strong>s The Zeeasterweg plant at Lelystad of Netherl<strong>and</strong>s is an aerobic tunnel composting plant <strong>and</strong> is the most up-to-date of its kind. The plant has been designed <strong>and</strong> constructed by the Dutch company Orgaworld. It processes a variety of waste including industrial waste, green waste, residual waste <strong>and</strong> sludge from the food-processing industry <strong>and</strong> has an annual capacity of 75,000 tones. It receives organic waste from the Municipality of Lelystad which has
