The HydroPure Sludge Treatment System ("STS") is a combination of the HydroPure Tri-Phase Centrifuge system, HydroPure PetroChem chemical treatments, and application know-how which was developed from several years of processing the most difficult oily sludge projects known. The HydroPure STS has been used successfully to treat millions of barrels of oily sludge from lagoons, tanks, and other waste sources. Prior to every STS installation have been failed attempts by waste site owners and/or centrifuge service companies. HydroPure has achieved a 100% project success rate in all of its applications.

The HydroPure STS separates oily sludges into pipeline grade oil (greater than 99% purity), clear water, and dry solids. In many STS applications, the sludge is treated for the value of the recovered oil which is sold to crude oil marketers and placed into pipelines. In all STS applications, waste producers dramatically reduced their waste liability while recovering valuable hydrocarbons from their sludge.

HydroPure offers its STS systems in two size configurations. The STS-200 will process up to 200 cubic meters (approximately 1,300 barrels) of sludge per 24-hour day. For higher processing volumes, the STS-475 can process up to 475 cubic meters (approximately 3,000 barrels) per day. The STS systems can process sludges varying from 0% to 99% hydrocarbon contents, 0% to 99% water contents, and up to 40% solid contents. If the solid content in a particular application is above 40%, the sludge can be diluted with water to enable the STS to effectively process the material. Regardless of the oil/water/solid composition of the sludge, the STS will recover 100% of the liquid hydrocarbons from the material.

The HydroPure STS can be mounted on a skid, into a shipping container or installed permanently into the customer's facilities. If the customer requires mobile processing capabilities, HydroPure can configure a self-contained unit in a trailer or shipping container engineered to minimize project mobilization and demobilization times.

The STS systems can be engineered with control systems varying from full to low automation depending on the customers needs. Even the most basic control package has the necessary safety shutdowns to ensure operator safety and prevent equipment damage.
