Industrial Waste Water,
Minerals and Oil

Residues containing oil are created wherever oil is extracted or processed. Flottweg decanters, Tricanter®, separators and systems offer an environmentally friendly solution to the following applications in the processing industry:

Flottweg decanters, Tricanter® machines and separators process different residues containing oil.

Our centrifuges are used in:

• Processing of wastewater containing oil
• Processing of oil sludge from ponds and lagoons
• Processing of residues containing oil from the cleaning of crude oil tanks

The Flottweg decanter guarantees optimum treatment of the gravel wash water and sand washing water. For example, a treatment system with a Z92 from Flottweg can process up to 2200 tonnes of sludge daily.

Flottweg decanters are used worldwide in the steel industry and are an important constituent in cleaning of various exhaust gases and wastewater in steelworks:

• Furnace gas cleaning
• Converter gas dedusting
• Scale slurry processing
• Pickling slurry processing
• Sewage slurry processing
• Water circuit cleaning

During processing of tar in coking plants, decanters separate the solid impurities out of the raw tar. The cleaned tar contains less than 0.3% quinolin. The separated solid has a total dry solids of approx. 33 - 40% and its consistency is between clumpy and almost solid.

In the processing of drilling slurry, drilling emulsion and drilling muds, all substances that have entered the emulsion during the drilling process are separated out. While the riddle screens and hydrocyclones separate coarse-grained particles, the decanter deals with the small particles.

In mining, decanters can be used in numerous applications involving processing minerals and ores.
