Waste stabilisation and solidification

Stabilisation and solidification units

A stabilisation/solidification unit is an industrial treatment centre whose aim is to obtain at its output a stabilized product admissible to a Hazardous Wastes Storage Landfill Facility.
It comprises mainly the following components:

• Storage silos and tanks: Wastes and reagents.
• Conveyor system (Archimedean screw, belt conveyor),
• Component weighing and dosing chain,
• Mixing module,
• Installation automatic controller and supervisory system.

The industrial implementation of the stabilization/solidification processes calls for special engineering including notably the following steps:

• Studies needed to prepare the regulatory files,
• Chemical engineering studies to determine the treatment formulation,
• Outline Design, Detailed Design studies,
• Industrial unit construction,
• Unit mechanical acceptance and commissioning,
• Technical and chemical assistance to operation throughout life.

Our proposal can be set out in the form of turnkey contracts, prime contracting or customer technical assistance.
