Recycling plants & landfills

Water in landfills

Recycling facilities and landfills face a number of challenges when it comes to treating contaminated water. Climate change leads to periods of large amounts of rainfall, which has consequences for, among other things, the leachate in landfills. Nordisk Vannteknikk supplies solutions for treating leachate, as well as other innovative solutions for cleaning and recycling resources.

Leachate

Leachate from landfills contains many different forms of pollution and must be cleaned before it is released into public sewers.

Reception of masses

Facilities for receiving contaminated masses from sand traps, wash halls and oil separators. 

Leachate

Nordisk Vannteknikk has good experience in cleaning leachate from landfills. In collaboration with our partners, we have developed technologies for efficient treatment of leachate, and deliver everything from planning and assembly, to consumables, service and full operation.

What is 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 bring contaminated water into the groundwater. It is therefore incredibly important that we ensure that the pollutants are separated before the water is released.

Process

Nordisk Vannteknikk has good experience with the challenges associated with leachate. The technology we deliver have the ability to significantly reduce pollutants linked to leachate at landfills. These substances include heavy metals, phosphorus, organic substances, and suspended matter.

Our leachate systems are supplied with a number of components which together ensure very good 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 press where the sludge is effectively dewatered for dry sludge.

Our methods have proven to be effective, but all projects are different. We therefore work closely with each and every customer to be able to find the very best solution for you and your challenges.

Oil separation

Liquid masses from sand traps, wash halls and oil separators have traditionally been sent to landfill.

Nordisk Vannteknikk has developed Norway's first facility for receiving liquid masses where oil, sand and gravel are separated before the water is purified and the sludge is removed.

The facility has a strong focus on reuse and is a major contribution to efficient resource recovery.
