New observations of non-indigenous species (NIS) in coastal waters, such as the Gulf Cadiz (Spain) have increased since 1980 and more or less exponentially last five years. Ballast water has become most significant pathway for unintentional introductions NIS into marine ecosystems. For example, larvae crustacean decapods that inhabit column could be transported ballast water. Although elevated ...

The removal of turbidity, particles, phytoplankton and zooplankton in water by crumb rubber filtration was investigated. A substantial reduction was achieved. Of the three variables, filter depth, media size and filtration rate, media size had the most significant influence. Smaller media size favored higher removal efficiency of all targeted matter. There was no apparent relationship between r...
