Swedrop demonstrate a prototype filter for extingushing water in storm water drains, to the Swedish Civil Contingencies Agency (MSB).

As an response to enquiries from graffiti removals, facade works, road works etc. about a storm water filter for intermittent use, rather then a year, Swedrop AB have looked in to the feasability of producing a cost efficient filter for shorter deployments.
ZWIFF by Swedrop is designed on the same concept and with the same absorbents as the Swedrop XL but uses a textile envelope. ZWIFF is lowered into the storm water drain where it absorbs heavy meatals, PAH, oils, organic pollutants etc. After use, the whole filter is sent to incineration.
MSB are evaluating methods and products for cleaning extinguishing water. Our Fire Departments have a mission to protect life and property in case of fire. But also to minimize the environmental impact of any emergency response. ”People, Property and Place” as they say in the business.
