Throughout the entire world, Alfa Laval is recognised as a very competent supplier of decanters for sludge dewatering at purification plants. Alfa Laval’s competency within this area is unrivalled and that is why Stjernholm has decided to cooperate with Alfa Laval with regards to marketing decanters within the Danish market.
The Aldec series consists of 3 different machine series: Aldec, Aldec G2 and Aldec G3. They are all based on the same, thoroughly tested technology. Only the local conditions determine the optimal type of decanter to use: capacity needs, control requirements, space, requirements related to dewatering degree, requirements with regards to expansion options etc.
Separation takes place in a horizontal, cylindrical ball which is equipped with a conveyor. The medium is led into the ball through a stationary inlet pipe and it is smoothly accelerated by means of an inlet rotor. The centrifugal force leads to dry matter depositing on the ball wall. The conveyor rotates in the same direction as the ball, but at a different speed, making the dry matter move towards the conical end of the ball by the sludge outlet.
No matter which model you select, you will get a very compact decanter with a high degree of cost-effectiveness and operational reliability, and easy handling. The Aldec series has fully enclosed process sections, thereby offering a high level of hygiene.
