The CTU is a water treatment unit, which means it can treat polluted liquids with characteristics similar to seawater. The unit can efficiently treat water at a rate up to 20 m³/h with pollutants as low as 2.5 ppm (lowest measurable value on Infracal). The OIW capacity and PPM efficiency depend on the installation setup.
The unit generates approximately 5-10% (of the inlet OW) foamy sludge that will be discharged into a mobile tank/skip for disposal onshore. The foamy sludge is still fluid and contains a lot of water (>95%), so it may be pumped to a sludge tank at the installation and further dewatered with the STU.
