Hydro Launches First Defense for economical surface water treatment

Hydro International’s innovative First Defense vortex separator is now available for the first time in the UK, in response to the growing need for economical surface water treatment on new developments, car parks and highways.

The First Defense uses a gentle vortex action to remove coarse particles, litter and oil from surface water runoff – a requirement which will become increasingly important as a result of growing regulation for Sustainable Drainage Systems (SuDS) in future.

The internal components of the First Defense are designed to create a low energy rotational flow within the chamber, allowing sediments to settle to the sump, while oils, floating litter and debris rise to the upper containment area. Harmful pollutants are therefore captured safely within the device, protecting public areas.
