WHAT WOULD YOU SAY IF SUSTAINABLE WASTEWATER DISPOSAL AT THE SAME TIME REDUCES YOUR COSTS?

Green Ocean can treat wastewater and sewage sludge containing highly toxic, heavily or non-biodegradable chemical compounds with COD from 3.000 to >100.000 mg O2/l and also milky, cloudy, coloured and solids-containing wastewater smoothly and with a high potential for savings…

INDICATIONS FOR PROBLEMATIC WASTEWATER

Green Ocean’s technologies can dispose problematic wastewater environmentally-friendly in practically all industrial sectors …

Indications for problematic wastewater:
  • Operations during summer and winter show different problems
    – i.e. de-icing at airports

  • Nitrification inhibition – transformation of ammonia to nitrate  =>  toxic to fish

  • Corrosion inhibitors, cooling lubricants, oily residues caused by industrial processes related to drilling, cutting or milling

  • Spent caustic (consumed lye)

Oxidative treatable classes of compounds – indicative:
  • Persistent, biologically not degradable, toxic organic compounds, heavy metal salts
  • Persistent pollutants, i.e. tensids, fatty hydrocarbons, particulate organics, i.e. synthetic polymers etc.
  • Persistent, toxic organics, natural and mineral greases and oils, polar and non-polar emulsifiers and dispersants, synthetic polymers, synthetic resins,  heavy metal salts
  • Persistent, biologically not degradable, toxic and carcinogenic organic compounds, synthetic polymers, tensids, dispersants, dyes, heavy metal salts, etc.
  • Dyes, plasticizer polymers, tensids, natural and synthetic polymers, synthetic resins, silicone oils etc.

 

METAL PROCESSING

The disposal of cooling lubricants need to separate the major part of mineral oil components.

The residual aqueous phase, subsequent to the removal of oil hydrocarbons by flotation, contains high concentrations of heavily or non-biodegradable chemical compounds.

These chemical compounds need to be pre-treated prior to the treatment in a central wastewater treatment plant.

Green Ocean offers to all of these chemical compounds reliable, environmentally-friendly and cost-efficient wastewater processing.

ELECTROPLATING AND CIRCUIT BOARD PRODUCTION

Electroplating processes and those to produce printing circuit boards are associated with the generation of exhausted process liquids and wastewater streams which contain toxic and/or heavily or non-biodegradable chemical compounds.

These chemical compounds need to be segregated and pre-treated prior to the treatment in a central wastewater treatment plant.

Green Ocean offers to all of these chemical compounds reliable, environmentally-friendly and cost-efficient wastewater processing.

REVERSE OSMOSIS

Wastewater from industrial installations is increasingly recycled. For this purpose, reverse osmosis plants are used subsequent to other treatment steps.

In many cases, the resulting concentrates contain high concentrations of toxic and/or heavily or non-biodegradable chemical compounds which need to be pre-treated prior to the treatment in a central wastewater treatment plant.

Green Ocean offers to all of these chemical compounds reliable, environmentally-friendly and cost-efficient wastewater processing.

WASTE SLUDGE

The disposal of sewage sludge from biological sewage treatment plants (municipal or industrial) creates major problems.
Main reasons are:

  • Bans on sewage sludge utilization in agriculture
  • Disturbance of the anaerobic and aerobic stages as well as poisoning of the microorganisms by poorly biodegradable or non-biodegradable substances
  • High environmental and climate impacts from sewage sludge drying and incineration

Wet oxidation of waste sludge is a highly efficient and cost-effective solution for the sludge and the metabolit problems and can reduce the volume of sludge to a minimum – directly and at the place, where it occurs.

CHEMICAL INDUSTRY

Many syntheses of chemical compounds are associated with the generation of so-called mother liquors, filtrates, washing waters, cleaner waters, scrubber liquids etc. which contain toxic and/or heavily or non-biodegradable compounds.

These compounds need to be pre-treated prior to the treatment in a central wastewater treatment plant.

Green Ocean offers to all of these chemical compounds reliable, environmentally-friendly and cost-efficient wastewater processing.

OIL - & GAS INDUSTRY

In the oil and gas industry, certain individual wastewater streams are generated, such as spent caustic from ethylene production plants.

These wastewater streams contain sulfidic constituents and heavily or non-biodegradable compounds.

These chemical compounds need to be treated prior to the treatment in a central wastewater treatment plant.

Green Ocean offers to all of these chemical compounds reliable, environmentally-friendly and cost-efficient wastewater processing.

LANDFILL LEACHATE

Leachate from landfills contain a large variety of organic compounds which are toxic and/or heavily or non-biodegradable.

Wet oxidation of the organic compounds of leachates is a highly efficient and cost-effective solution.

Green Ocean offers to all of these chemical compounds reliable, environmentally-friendly and cost-efficient wastewater processing.

TEXTILE FINISHING INDUSTRY

In textile wet processing industries, a number of individual waste streams contain heavily or non-biodegradable chemical compounds, which cannot be adequately treated in central wastewater treatment plants, such as:

  • Wastewater from the pre-treatment of fabrics made of synthetic fibres,
  • Desizing liquors containing synthetic sizing agents,
  • Residual padding liquor for dyeing,
  • Residual padding liquor for finishing,
  • Certain washing waters etc.

Green Ocean offers the ultimate solution, i.e. the complete oxidation of these chemical compounds or their conversion into biodegradable compounds.

PAPER INDUSTRY

The coating of paper with chemical specialities can be associated with residues and individual wastewater streams which contain toxic and/or heavily or non-biodegradable chemical compounds, such as bisphenol-A or bisphenol-S.

These chemical compounds need to be pre-treated prior to treatment in a central wastewater treatment plant.

Green Ocean offers to all of these chemical compounds reliable, environmentally-friendly and cost-efficient wastewater processing.

TANNERIES

From the discontinuous tanning and finishing processes for leather manufacture, certain baths contain toxic and/or heavily or non-biodegradable chemical compounds.

These chemical compounds need to be segregated and pre-treated prior to the treatment in a central wastewater treatment plant.

Green Ocean offers to all of these chemical compounds reliable, environmentally-friendly and cost-efficient wastewater processing.
