Drying technologies for sewage sludge

cement works. The dry granulate is pro-duced from the dewatered sewage sludge, which serves as carbon neutral auxiliary fuel in the cement kiln to generate heat for cement production. The sewage sludge ash is used as an additive in cement pro-duction and thus reduces the amount of minerals used. The advantages of the sewage sludge heating
