Green Ocean’s approach of the innovative integrated wastewater processing includes besides the development of innovative processes for problematic wastewater, the sustainable optimisation of resource efficiency (water, energy, chemicals) and the environmentally-friendly disposal of highly toxic and heavily to non biodegradable substances in wastewater and exhaust air.

When it comes to optimising resource efficiency, we offer special expertise in process optimisation and the development of water management systems.

Green Ocean’s focused criteria for wastewater processing and disposal of problematic wastewater are

• Degree of mineralization of the organic load,
• Degree of elimination of organic load,
• Space requirements and integrability into the operational infrastructure and
• Plant operation (continuous vs. batch) of the wastewater process and
• Investment and operating costs of the disposal process. 

With the implementation of a two-stage disposal concept consisting of special chemical processing and a biological disposal stage, Green Ocean creates environmentally-friendly disposal for highly toxic problematic wastewater with high cost efficiency and economy compared to – more common on the market – expensive end-of-pipe solutions that are harmful to the environment.

We finance, build and operate the systems, which are tailored to the specific needs of our customers, and integrate them into the customer-specific production process.

Thus, Green Ocean offers its customers a next generation all-round carefree service model across the entire life cycle of its innovative integrated wastewater processing.

Wastewater with oily ingredients (e.g. mineral oils, organic oils, lubricants, non-polar dispersants and emulsifiers) as a liquid or solid phase, require efficient separation in order to enable adequate disposal.

The quality of the oil separation as the first process stage has a decisive influence on the disposal result.

Green Ocean’s FRES:H® – Flotation Reactor for Efficient Separation of Hydrocarbons – in comparison to existing technologies offers very high extraction efficiencies of > 90% as well as a high flexibility in relation to changed wastewater pollutants but in addition low space requirements.

An additional advantage is the possible integration with the ORCAN® process for the oxidative treatment of the wastewater pollution that is still present in the aqueous phase.

Depending on the origin of the wastewater, the floated ingredients can then be recycled or oxidatively converted into biodegradable substances.

With its innovative flotation technology, Green Ocean can convert the most complex, biologically non-disposable wastewater into biocompatibility.

The resulting fields of application are primarily in process wastewater from the chemical and cosmetic industries, mineral oil, mechanical engineering and textile industries and, in particular, in wastewater from industrial landfills. 

Green Ocean’s objective in process optimisation is significant increase in productivity and optimisation of resource efficiency for our customers as well as the reduction environmentally relevant problematic substances.

We have long-lasting experience in the precise analysis of technical chemical production processes, mathematical simulation and the risk-minimized implementation of optimised process designs.

The resource efficiency in the pre-treatment of cotton and man-made fabrics were significantly optimised:

• >70% reduction of water and energy consumption
• c.25% reduction of chemical input
• Washing efficiency and productivity significantly improved

The minimised quantities of wastewater from the washing process contain heavily or non-biodegradable chemical compounds, which are “introduced“ to the textile fabric.

Green Ocean’s wet oxidation technologies eliminate this problem – tailor-made to the specific customer application.

The core elements of a successful integration of wastewater treatment targeted as defined chemical processing in practice are the statistical planning and examination of laboratory trials as well as the reaction modelling.
