Industrial stormwater is a consequence of snow and rain that lands on industrial sites. The runoff water can often become polluted due to the handling and storage of materials that contain substances that are hazardous for the environment. 

What to look for in a treatment solution for surfacewater


Choose a solution that endures a variating water flow

We recommend that you choose a technology that is engineered to cope with a large variation in the amount of water that flow through the treatment facility. This is one of the biggest obstacles to tackle when it comes to treating surface water. 

Some of our customers expressed a need for a solution for treating stormwater - we set a goal to design and offer an effective and user-friendly solution.


Choose an automated solution

Our product, the Mivanor StormWater, is a unit that is based on a filter technology. The filter flows on top of the water in large tanks and cleans the water as it runs through the filter. The result is an automated and effective treatment facility.

The solution is developed together with Swedrop, the company who has designed the filter. The filter is a combination of different types of water filtration media. These include an oil absorbent, activated charcoal and combustion slag.

When the filter is "filled up" it is easy to replace it with a new filter.
The Mivanor Stormwater treatment system has a capacity of 10 m3 of water per hour.


How you obtain an optimal residence time?

To reach an fully automated process and an optimal residence time the length of the treatment time is adjusted due to the amount of water that is collected in the bassins.

When there is a lot of rainfall, the treatment time is reduced and at low levels the treatment time is set to a maximum. 

Mivanor Surfacewater Treatment System

What treatment effects can you expect?

Tests and studies of our treatment process has proven a very good degree of treatment, both of organic and inorganic substances. The copper levels of the water after treatment is often an important indicator of how well the treatment works. Mivanor Stormwater has proven to obtain a removal of 95 % of the copper substances in the surface water.

Mivanor StormWater is designed to absorb several kinds of pollution from surface water:

  • The 33 substances EU prioritize due to environmental hazard
  • Polycyclic aromatic hydrocarbon (PAH)
  • Heavy metals, including;
    • Cadmium
    • Copper
    • Zinc
    • Nickel
    • Lead
    • Mercury
