Wastewater treatment in the energy industry is essential for the safe and efficient operation of power plants, incineration plants and substations. These facilities generate different wastewater streams containing a wide range of contaminants. Wet flue gas cleaning produces acidic and alkaline wastewater that may contain heavy metals. Mercury (Hg) in particular requires targeted and professional treatment. At the same time, maintenance work or leaks from high-voltage transformers can cause transformer oil to enter secondary containment areas. OKO-tech develops tailored treatment solutions for these wastewater streams, helping to ensure effective treatment and reliable process operation.
Products for this industry
Energy-Efficient Treatment of Transformer Oil-Containing Wastewater
OKO-tech treats transformer oil-containing wastewater from secondary containment areas using OKO-aquaclean Emulsion Breaking Systems, which separate oil and water with low energy requirements. This reduces the amount of waste requiring disposal, while the treated water can be reused where appropriate. Our systems can be integrated into existing production and operating processes, helping to improve resource efficiency and reduce operating costs. This enables companies in the energy industry to achieve economical and resource-conscious wastewater treatment.
Physico-Chemical Treatment of Acidic and Mercury-Containing Wastewater
We neutralise and treat acidic and mercury-containing wastewater from flue gas cleaning processes using Physico-Chemical Treatment Systems. These systems are designed to remove dissolved heavy metals, support stable treatment processes and meet applicable discharge requirements. By combining neutralisation and heavy metal precipitation, our systems provide targeted treatment for wastewater streams generated in the energy industry.
Treatment Processes for Wastewater in the Energy Industry
The energy industry generates wastewater containing a wide range of contaminants, including oil residues, emulsions, fats and inorganic substances. OKO-tech develops industry-specific treatment solutions based on the characteristics of each wastewater stream and designed for integration into existing operating processes.
Depending on the type and concentration of contaminants, treatment may include heavy metal precipitation in batch or continuous-flow operation, targeted flotation for the separation of oils and fats, and specially designed emulsion breaking systems for wastewater containing emulsions. Evaporators can also be used to treat wastewater containing difficult-to-degrade or non-volatile substances.
