Green Ocean stands for leading-edge technology and defined chemical process engineering
– integrated into the specific production process of the customer.


Specialised know how and long-lasting experience in various industrial sectors

Our experts have specialised know how and long-lasting experience with the profound analysis of production processes with respect to pollution prevention and control as well as with the successful implementation of sustainable solutions in various industrial sectors.

Besides the highly effective and cost-efficient wet oxidation technology, Green Ocean also offers flotation techniques for wastewater containing hydrocarbons.

The knowhow does include both the optimisation of production processes and the combination of different wastewater treatment, especially the wet oxidation of concentrates from membrane separation plants and anaerobic treatment plants.

In many cases, the interaction of central biological treatment plants with the wet oxidation of problematic wastewater streams is of particular importance.


Environmentally-friendly and efficient disposal of toxic and/or non-biodegradable substances in wastewater

Green Ocean’s wet oxidation technologies meet all requirements of a modern, next generation disposition strategy and provide:

  • Reduction of toxic and/or non-biodegradable chemical compounds by 70-90%

  • Minimised operations costs

  • Sludge-free disposal

  • Biocompatibility of the residue

  • Continuous, fully automated process

  • Low maintenance

  • Low space requirement

The constituent substances of concentrated wastewater can cause considerable problems in biological wastewater treatment plants (inhibiting or toxic effects).

Green Ocean’s oxidation technologies convert those substances and/or heavily or non-biodegradable chemical compounds to a great extent into water and carbon dioxide. The residual load, after the oxidative pre-treatment, has a high degree of biocompatibility and therefore can be mineralised in a central biological treatment plant (communal or industrial) without disturbances.

We can supply our oxidation technologies both pre-manufactured as well as fully integrated into existing production structures.

Our range of systems comprises treatment units of 1 m3/h  to 12 m3/h.

Green Ocean’s disposal concept focuses on targeted treatment of individual segregated wastewater streams containing toxic and/or heavily or non-biodegradable chemical compounds. Therefore our technologies can be used in virtually all industrial sectors.

Our oxidation technologies are particularly suitable for the pre-treatment of heavily polluted effluent, such as
  • Landfill leachate and process wastewater

  • Wash-water flow from exhaust-air cleaning


Efficient separation of emulsified and disperse hydrocarbons (mineral oil)

Green Ocean’s dissolved-air-flotation removes specifically – with or without use of chemicals – emulsified and disperse mineral oil hydrocarbons, i.e. of cooling lubricants, by more than 90% with subsequent thermal disposal of the flotate.

The aqueous phase can still contain high concentrations of heavily or non-biodegradable organic additive, which can be treated highly effective by Green Ocean’s oxidation technologies.


Tailor-made wastewater processing and optimisation of the resource efficiency in the production process

Green Ocean combines the specialised know how of its experts in chemical process engineering and their long-lasting track record in the implementation of water management systems with the know how of its customer’s production experts for tailor-made solutions of the treatment of problematic wastewater and the careful integration into the production process.

Processing – following Green Ocean’s understanding – includes the chemical-analytical examination of the production process, which may also include the optimisation of alternative scenaria using mathematical simulations.

Continuous washing process after optimisation

The resource efficiency in the pre-treatment of cotton and man-made fabrics have been 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“ with 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 as targeted defined chemical processing are the statistical planning and examination of laboratory trials as well as the reaction modeling.


Measured and modelled values

The reaction modelling is a prerequisite for the rapid adaption of the process to varying wastewater compositions, which in practical applications frequently occurs.

Green Ocean’s oxidation technologies on the one hand mineralises the organic compounds to carbon dioxide and water and on the other hand converts non-biodegradable chemical compounds into biocompatible substances.


Customised solutions, directly integrated into customer’s production lines

The increasing chemicalisation of the aquatic ecosystems by heavily or non-biodegradable chemical compounds needs effective solutions.

Green Ocean’s wet oxidation technologies make an excellent solution to this pressing problem available.

They provide highly efficient, well-developed and reliable methods for the oxidation of chemical substances or the conversion into biodegradable  compounds and therefore render these toxic compounds harmless. This, highly cost efficient and environmentally-friendly.

The illustration above shows a simplified schematic of an ORCAN wet oxidation facility. In practical applications, it is applied similar to a defined chemical production process. This includes also process-related modeling.
