In addition to our expertise, the benefits of our services include the prompt launch of services and our ability to customise water treatment methods to meet the customer's needs. We use the infrastructure of existing plants, supplementing them if necessary with units required for pre-treatment.
We provide water treatment services for the different phases of industrial manufacturing processes - including:
We plan and implement the treatment of process waters on site. We improve the recycling rate of the plant by recycling water back into the process. This helps to reduce the volume of water going down the drain, which both protects the environment and saves costs.
We identify solutions for the further treatment and reutilisation of the waste generated by water treatment.
Many hazardous, soil-contaminating substances are water-soluble and may have settled in the groundwater from soil contaminated earlier. Pumping and cleaning can prevent hazardous substances from spreading into a larger area.
The most efficient way to treat groundwater is to remove the source of the discharge. In the remediation of a contaminated site, we take account of the need to clean both the groundwater and the soil. We will identify a method or the combination of methods that is most appropriate for the particular site.
When contaminated soil is remedied through soil disposal, the ditch may become filled with water contaminated with the same substances as the soil.
We treat ditch water in two different ways. If the volumes are large, on-site treatment is the simplest solution. If the volumes are small, we will collect the water to be treated by one of our Nordic plants.
The amount of waste may be reduced by drying the sludge, which helps to minimise the costs of treatment and the need to transport waste. In many cases, the extracted water may be returned to circulation on site.
At the time of drying, the sludge may be treated to recover raw materials suitable for further use from the waste, minimise the hazardousness of the waste and improve the opportunities for final disposal. This helps return raw materials to circulation, saves costs and reduces the environmental impact.
We remedy restorable municipal and industrial dumping grounds, build landfill treatment systems and maintain landfills.
In leachates from landfills as well as water generated in waste treatment sites, the concentrations of contaminants may still exceed target values, even if the waste is pre-treated and the landfill body is already restored. In this case, the water must be treated before it goes to a municipal or other public treatment plant.
Sometimes it is reasonable to treat the leachate before it leaves the landfill. This way, it is possible that the water may not have to be drained at all, and it may be possible to apply for a permit to release it directly into the water system.
Fortum receives and treats liquid waste generated in sewage maintenance, such as sand, oil and grease trap waste. Our equipment separates the fractions suitable for material reutilisation from the treated waste, which are then used to replace virgin materials in applications such as environmental construction.
We also actively seek new reutilisation applications for the fractions separated from sewage waste. Fractions that are not suitable for material reutilisation go to licensed energy recovery or disposal.
