  • Patent number: 7820054
    Abstract: A method of removing solids from the slurry at a construction site located on or near a stream in order to improve the quality of water discharged into the stream by forming treatment zones for receiving slurry, said zones comprising walls of filter bags and floors of filter skirts, said bags and skirts comprising geotextile material and the bags being filled with a shredded rubber and woodchip combination.
    Type: Grant
    Filed: January 12, 2009
    Date of Patent: October 26, 2010
    Assignee: Denny Hastings FLP 14

  • Publication number: 20090047076
    Abstract: An erosion control system and method wherein a fabric filter bag is embedded with and/or filled with a flocculating polymer and is positioned on a sloping soil surface to dam and pond water flowing thereacross for settling of the particles in the water, and as the ponding water seeps into the bag the colloidal particles will be filtered or agglomerated for settling. The water then passes through and out of the bag and is further subjected to agglomeration and filtering by a skirt of filter material also impregnated with flocculating polymer, said skirt being anchored to the bag or stacked to maintain the position adjacent and downslope from the bag.
