Recycling & landfill
From landfill to recycling and reuse.
Recycling stations and landfills face a number of challenges when it comes to treating contaminated water. Climate change leads to periods of heavy rainfall, which impacts leachate management in landfills, among other issues. Nordisk Vannteknikk provides advanced solutions for leachate treatment, along with other innovative technologies for purification and resource recycling.
Leachate​
Leachate from landfills contains many different forms of pollution and must be treated before being discharged into public sewers.
Reception and treatment facility
Facilities for receiving and treatment of contaminated fluids from sand traps, wash halls and oil separators.
Leachate
Leachate is rainwater and surface water that flows through cracks in the ground and into the groundwater. The groundwater that is formed is used for various purposes around the world, including drinking water. When this water seeps through landfills or other places with pollution, it will mix and contaminated water will end up in the groundwater. It is therefore incredibly important that we ensure that the pollution is removed before the water is released.
Nordisk Vannteknikk has extensive experience in treating leachate from landfills. In collaboration with our partners, we have developed technologies for effective treatment of leachate, and deliver everything from design and installation, to consumables, service and full operation.
The process
Nordisk Vannteknikk has extensive experience with the challenges associated with leachate. The systems we supply have the potential to significantly reduce pollutants associated with leachate at landfills. These substances include heavy metals, phosphorus, organic substances, and suspended solids.
Our leachate treatment plants are supplied with a number of components that together ensure strong results, both in terms of water purity and sludge production. The process starts with aeration of the water in containers before it flows on for chemical precipitation with polyclay and sodium aluminate in a lamella separator system. The sludge that is removed is transported to a sludge press where the sludge is effectively dewatered to produce dry cakes.
Our methods have proven to be effective, but every project is different. We therefore work closely with each and every customer to find the very best solution for you and your challenges.
Oil treatment
Liquid oily waste, such as from oil separators or grit traps, have traditionally been disposed as dangerous waste at landfills. However, Nordisk Vannteknikk has developed a plant that has the ability to treat these masses and significantly reduce the amount of disposed landfill.
The plant separates both oil and sand before the water is purified. The water is also reused in the plant for flushing, and can also be reused for other purposes or safely discharged to the pyblic sewer system. The sand masses and sludge that are produced can also be reused for various purposes.
SMB facility
The fluid mass reception facility (SBM) in Drammen is the first of its kind in Norway. The facility is a prime example of how modern technology and innovative treatment solutions can help reduce the environmental footprint of the oil industry.
