INNOVATIVE INTEGRATED CHEMICAL PROCESSING
Tailor-made wastewater processing and optimisation of
the resource efficiency in the production process
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.
Green Ocean’s innovative integrated wastewater processing enables a significant step towards water circularity

ORCAN® – ADVANCED OXIDATION
Environmentally-friendly and highly efficient disposal of toxic and/or non-biodegradable substances in wastewater
The constituent substances of concentrated wastewater can cause considerable problems in biological wastewater treatment plants (inhibiting or toxic effects).
ORCAN® – Oxidation Reactor for Carbon and Nitrogen Compounds – can treat highly concentrated wastewater flows and residues with a chemical oxygen demand (COD) of 3’000 to > 100’000 mg O2/l and also milky, cloudy wastewater containing solids without any problems.
ORCAN® provides a continuous, practically sludge-free disposal of highly toxic, heavily to non-biodegradable compounds in wastewater.
ORCAN® can be used at the point of origin of the concentrated wastewater streams (industrial operation) as well as pre treatment or post treatment in a biological sewage treatment plant (industrial or municipal).
The toxic and heavily to non-biodegradable compounds are largely converted into water and carbon dioxide (COD reduction of 70 – 90%).
The residual load after the oxidative treatment shows a high biocompatibility (BOD5 / COD > 0.6 – 0.9), which can be mineralised without any problems in a central biological sewage treatment plant.
In contrast to physical separation processes, ORCAN® does not require any interim or final storage of non-biodegradable wastewater constituents or sewage sludge.
ORCAN® thus fulfills all the requirements of sustainable resource efficiency and can completely replace conventional incineration processes in the disposal of highly toxic and heavily to non-biodegradable wastewater as an environmentally-friendly process, without causing by-products, such as dioxins, furans, sulfur dioxide, nitrogen oxides or sewage sludge.
ORCAN® – FUNCTIONAL PRINCIPLE
Conversion of organic pollutants in the water phase to CO2 and water
The basic principle of the ORCAN® process consists of a catalytic oxidation of the wastewater constituents with oxygen and hydrogen peroxide.
The toxic and heavily to non-biodegradable wastewater constituents are hydrolysed in the water phase to low molecular weight, biodegradable fragments and, as far as necessary, are oxidised in stages to carbon dioxide and water – sludge-free.
ORCAN® process uses air, hydrogen peroxide and an iron catalyst to convert organic compounds in the aqueous phase into carbon dioxide and water – sludge-free.
The biocompatibility of the residual load (fragments) is strongly related to the degree of oxidation of the wastewater constituents.
As a continuous, autothermal process, ORCAN® enables 24h/7days operation at medium temperatures and low pressure and achieves reaction conversions of 5 to > 10 kg COD / m3 h (space-time yield).
The range of systems extends from small, compact modular systems (space: 30 – 50 m3) for the treatment of 1 m3/h to 12 m3/h and is easily scalable.
ORCAN® can be supplied both pre-manufactured as well as fully integrated into existing company structures.
FRES:H® – ADVANCED FLOTATION
Efficient phase separation of emulsified and disperse hydrocarbons
– e.g. mineral oil, lubricants
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 state-of-the-art 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.
– adapted to operational porocesses
Green Ocean offers its customers an all-round carefree service model accross the entire life cycle of its technologies.
We finance, build and operate the technologies that are tailored to the specific needs of our customers and integrate them into the customer-specific production process.
In practice, our technologies are applied like a defined chemical production process. This also includes process engineering modeling.
Green Ocean creates environmentally-friendly disposal of highly toxic problematic wastewater with high cost efficiency and economy for its customers – with no investment risk.
The range of systems includes units for the treatment of 1 m3/h to 12 m3/h and is easily scalable.
Green Ocean includes its long-lasting experience in the analysis, simulation and optimisation of production processes in wastewater management as well as the combination of its next generation technologies with other wastewater treatment processes, in particular membrane technologies with regard to concentrate disposal and anaerobic techniques.
In many cases, the interaction of central biological wastewater treatment plants with Green Ocean’s technologies is of particular importance.
RESOURCE EFFICIENCY OPTIMISATION
Process improvement – example textile chemical industry
– before optimisation
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.
– after optimisation
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.
