Water clarification plants

Clarification and dehydration systems created by Tecnoimpianti Engineering S.r.I. have been specifically studied for waters and mud resulting from the processing of marble, granite, ceramic and similar materials. The “closed circuit” clarification system have now become essential to an efficient and cost-effective production as they solve the problems rising from the water supply and the mud disposal as well.
These systems are produced with first quality materials and groundbreaking techniques.
They assure a non-stop clarification of the refluent waters and their reuse as well as a perfect dehydration of the mud making it dry and easily transportable.
Such systems – fully automated – limit operator’s interventions to simple inspections.


  1. Mud collection well
  2. Submerged pump
  3. Clarifier
  4. Station for polyelectrolyte preparation and dosage
  5. Pneumatic valve for mud discharge
  6. Mud stocking tank
  7. Press pump
  8. Filterpress
  9. Control panel
  10. Clarified water stocking tank

Waste water coming from the work process (1), are conveyed to the collecting well (2), then sent to the clarifier (3) through a submerged pump (2); the presence of the polyelectrolyte into the clarifier makes the suspended substances to precipitate. The polyelectrolyte coming from the preparation and dosing station (4) is injected into the waste water-lifting pipe. After the clarification processing, the water comes out to the stocking tank (10) to be recycled inside the plant while the solid substances (mud) settle into the clarifier cone are automatically discharghed through the pneumatic valve (5) into the mud collecting tank (6). A special pump (7) sends the mud to the filter-press (8) where solids and liquids now finally split. The pressed panels of mud are automatically discharged by the filterpress (8) while the liquids are recycled. The whole system is automatically controlled from the control panel (9), which is managed by a self-diagnostic PLC.
