  • Patent number: 6802978
    Abstract: A process of environmental including a micro application of floating/coagulating material in the watercourse, followed by micro flocculation to aggregate particles in suspension downstream, defining flakes of greater dimensions; submit the aggregated particles, dissolution and air injection, causing a micro floatation of aggregated particles; allowing a micro aggregation of the floating material downstream; next, the flow water is thrown into a streamlet/secondary effluent, submitted to air injection or aeration; a medium application of flocculating/coagulation material in this secondary watercourse to aggregate particles downstream, evidencing flakes of greater dimensions; submit aggregated particles downstream to dissolution and injection of air, submitting the urban watercourse to air injection or aeration intercalating, causing a macro floatation of aggregated particles and a macro aggregation of the floating material downstream; removing such material along an urban section before the effluent reaches th

  • Publication number: 20030085176
    Abstract: A process of environmental recovery in urban regions that acts along the entire watercourse mesh of an urban region, from the canalized domestic course of sewerage systems to the urban sections of riverbed, including the following stages: from the domestic section, such as a sewerage gallery, to promote a micro application of floating or coagulating material in the watercourse to be treated, whether rainwater or sewer matter; followed by micro flocculation, so as to promote an aggregation of particles in suspension downstream, defining flakes of greater dimensions; submit those larger aggregated particles in suspension downstream in this domestic watercourse to, at least one step of dissolution and air injection, causing a micro floatation of such aggregated particles; allowing a micro aggregation of the floating material to occur downstream, which will be removed from this domestic course before it reaches a streamlet or even a river effluent; next, after the flow of water submitted to a micro treatment is t
