In-house technologies for treatment of sludge
Uni-Recycling carries out turnkey projects including design, installation, operation and consulting with a record of over 1,000,000 m3 sludge in accordance with international standards. We are prepared for fast & efficient intervention in any location, using fully mobile equipment, on standard and non-standard pits & lagoons, carrying out the whole chain of operations for treatment of sludge from:
- Pits, lagoons, impoundments
- API separators
- Oily water discharges
- Tank cleaning sludges

Dewatering
We use three-phase centrifuges to simultaneously thicken and dewater solids while recovering oil and water. The process of centrifugation is an acceleration of the process of gravitational separation by the application of centrifugal forces. Three-phase centrifugation results in highest oil recovery. Centrifuges have several advantages over other dewatering options. They occupy a small space for a large throughput, and unlike filters, they do not require a building if adequate cold weather protection is provided. Centrifuges are continuous devices, which can minimize the buffer capacity required and the system can be almost entirely closed reducing emissions. Also, the scroll centrifuge can produce a truly solid product, although the solids will typically contain more moisture than that those from a gravity belt filter press.
Incineration
Incineration is a controlled combustion process for burning solid, liquid, or gaseous combustible wastes to an inert ash. In some cases, incineration is used for disposal of oily sludges and spent caustic in refineries and chemical plants.
Uni-Recycling provides many incinerators solutions which can be used for solid and semisolid wastes.
Stabilization
The addition of stabilizing agents will dewater sludge while destroying biological growth and odors. Since the reaction is exothermic, the water is both chemically combined and physically evaporated from the sludge. This method can be used for a variety of sludges.
