Rovaniemi overview
The material handling system for sludge incineration plant was part of the first Endev’s test plant for commercial use in Rovaniemi, Finland. Endev’s sludge treatment plant utilizes the sludge from the city wastewater treatment plant, aiming to recycle nutrients into a cost-efficient and safe fertilizer. The heat generated as a by-product is utilized in the city’s district heating network.
Material handling system for sludge
Laitex was responsible for the mechanical conveying system between Endev’s dryer and reactor. Wet sludge handling placed special demands on the tailored conveyor system.
The sludge is dried with hot sand, after which the dry material is fed into Endev’s own PAKU system. The PAKU technology has been developed to treat sewage sludge in order to minimize the amount of material transported from the wastewater treatment plant.
The conveying system Laitex supplied and installed has three phases:
- Sand feeding to the reactor
- Hot sand feeding to dryer and sand recycling
- Sludge-sand mixture feeding to the reactor.
This project emphasized a thorough understanding of the customer’s needs and the material being handled, excellent engineering expertise and co-operation.
