Abstract: The present disclosure provides for methods and systems for separating ultrafine particulate pollutants from aqueous suspensions. The present disclosure provide for methods and systems that can reduce the amount of ultrafine particulate pollutants from aqueous solutions, for example storm water runoff, which are not readily or easily removed using current state of the art techniques. In general, methods of the present disclosure provide for removing a portion of target ultrafine particulate pollutants using magnetic nanoparticles, which form aggregates with the ultrafine particulate pollutants. After a time period a magnetic field is applied and the aggregate can be separated from the aqueous suspension. Subsequently, the aggregates can be broken down and the magnetic nanoparticles recycled or reused while the ultrafine particulate contaminants are further processed, recycled, or disposed of.
