Nordic Water - Drinking Water Biostabilisation

The process we call biostabilisation is mainly used before other types of treatment at water purification plants. This process is completely biological and uses naturally occurring bacteria in the inflowing water to reduce odour, taste and levels of ammonium, iron, manganese or algal toxins.

Nordic Water - Turbid Surface Water Treatment

This process is based on a fundamentally more conventional treatment method – chemical precipitation and flocculation, followed by sedimentation and filtration. The difference is that it combines much more compact lamella sedimentation with continuous sand filters, allowing higher flow rates than conventional filtration.

Nordic Water - Contact Filtration

With its continuous filtration process, the DynaSand filter provides the basis for what we call contact filtration. This involves chemical precipitants being added into a mixer in the pipe system just before it reaches the filters. Hydroxide flocks form and are then coagulated, filtered and separated directly inside the filter bed. This process is particularly suited to treating surface water, especially raw water with a low to moderate level of...

Nordic Water - Extensive Phosphate Removal

If you want to keep phosphorus levels really low – at less than 0.1 mg/l – study after study has demonstrated that our final processing stage, which is based on chemical direct precipitation using a DynaSand filter, is the most cost-effective and reliable method available for municipal waste water treatment plants.

Nordic Water - Pharma

Nordic water has today two different well proven technologies for micropollutant reduction: 1) Based on adsorption or to some extent biological removal with Granular Activated Carbon (GAC). 2) Powdered Activated Carbon (PAC).

Nordic Water - Mill Scale Separation

Mill scale forms during steel production. It is a thin oxide coating that is created when steel is hot-rolled. When the steel is cooled down with water during the rolling process, the mill scale breaks off. The cooling water is re-used over and over again, which means that mill scale and oil residue particles need to be separated off. Mill scale often also contains valuable alloying elements such as tungsten, vanadium and molybdenum, which provides a...

Nordic Water - Side Stream Filtration

Many industries need cold water for their production processes. It is often cost-effective to use water as a heat carrier and to cool it down in cooling towers, for example. Particles can easily form in the cold water and need to be separated out of the recirculation system. To avoid having to process the entire recirculation flow, in most cases only around 2-3% is actually treated. This is known as a side stream. In larger industries, this apparently...

DynaAir - Air Compressor System

In recent years the demand for low energy solutions has encouraged the design of new technology for water and waste water treatment. The newly developed DynaAir unit supplies compressed air to DynaSand plants with much lower operational costs than earlier compressor systems.

Deni - Denitrification Tank Filter

Denitrification is generally performed in activation tanks. However, in many cases it is practical to partially denitrify the fluid in a DynaSand filter, the so-called DynaSand Deni. The denitrifying bacteria do not require oxygen - the filter bed therefore does not have to be aerated. External carbon sources must be added for denitrification, e.g. methanol or ethanol. Comprehensive testing has shown that suspended solids and phosphorus are separated...

Oxy - Filters

The DynaSand Oxy filter works according to the same continuous process principle as the tried and trusted conventional DynaSand filter. The aeration of the filter bed is the major difference in the process. A biologically activated filter is generally equipped with air nozzles in the filter bed. The nozzles are difficult to reach and tend to become blocked. In contrast to this, the DynaSand filter is equipped with a blockage-free air distributor. The...

DynaSand - Filter

Simplicity, reliability and ruggedness are the main features of the DynaSand filter. The function of the DynaSand is very simple: the feed is introduced in the lower end of a media bed and filtration takes place upwards. The lower end of the media bed separates the dirt particles, and is selectively and continuously removed from the bed by an air-lift pump for transportation to a media-washer placed above the media bed. The media particles are given a...

Rotoscreen - Model DS - Self Cleaning Fine Water Screen

Meva Rotoscreen DS is a self-cleaning fine screen for separation of solids from water. The screen has a very low flow resistance which results in a low head loss. This is an advantage at installations in open channels.
