DESCRIPTION AND SPECIFICATIONS
SAFE AND CORRECT USE
The SD unit realizes the dewatering of the sludge in small/medium sized plants. This machine, fabricated in stainless
steel, takes advantage of a patented thickening principle and of a mechanical dewatering principle. The liquid sludge
(solid concentration 0,8 - 5 %) is gathered until a solid content variable from 15 to 30% is reached (depending from
the kind of sludge, reactants and application field).
The sludge added to the reactant is introduced to the machine. A pre-thickener static mixer provides a first
thickening action. Then the screw transports the sludge in the dewatering zone where the action of mechanical
dewatering is emphasized.
Every other use of the machine will cause the termination of the warranty and will release FLUITECO from every
responsibility.
IMPORTANT:
SD Screw Press gives the performance required if the following conditions are totally satisfied:
1- The sludge to dewater is suitable to be dewatered with the sludge screw press.
2- The sludge is conditioned with polyelectrolyte to obtain the correct flocculation in term of size and consistency of the
flocs.
3- In the case Fluiteco supplied only the SD Screw Press without all others items of the sludge dewatering plant, including
Polyelectrolyte preparation and dosing system and sludge/polyelectrolyte mixing system, Fluiteco will respond only on
eventual mechanical defect of the SD sludge screw press and not about the performance of the SD screw press in term
of flow rate capacity, dryness performance and solids recovery performance,
Before switching off and restarting the machine it is necessary to proceed SISTEMATICALLY with a complete
washing cycle of the screen basket.
COMMANDS
The handling of the plant must take place automatically with the activation of the sludge feed pump.
WORKING PRINCIPLE, NOT PERMISSIBLE WORKING PRINCIPLE
The functioning of the machine is compromised if the solid matters:
•cannot be mechanically separated from the transporting liquid;
•agglomerate with themselves or with other parts of the machine;
•they compact theirselves or if they attach to the machine.
•did not receive an effective chemical-biological pretreatment up stream.
