Abstract: A modular porous swale. The modular porous swale may comprise a porous concrete block and filtration joint. The porous concrete block may snugly fit within a trench having a lower portion filled with an absorption media. The absorption media may include gravel, activated alumina, bone char, or an activated alumina and bone char mixture. The porous concrete block may have a top surface inwardly-sloped to a nadir. The filtration joint may be disposed within the porous concrete block and along the nadir. The liner may cover one or more sides of the porous concrete block. The perforated pipe may be located within the absorption media. The filtration joint may substantially align above a portion of the perforated pipe when the modular porous swale is installed within the trench.

Abstract: A modular porous swale filtration system. The modular porous swale filtration system may comprise one or more modular porous swales, absorption media, liner, and perforated pipe. Each modular porous swale may have a porous concrete block and filtration joint. The porous concrete block may snugly fit within a trench having a lower portion filled with the absorption media. The absorption media may include gravel, activated alumina, bone char, or an activated alumina and bone char mixture. The porous concrete block may have a top surface inwardly-sloped to a nadir. The filtration joint may be disposed within the porous concrete block and along the nadir. The liner may cover one or more surfaces of the trench. The perforated pipe may be located within the absorption media. The filtration joint may substantially align above a portion of the perforated pipe when the modular porous swales are installed within the trench.

Abstract: A treatment facility for removing toxic metals from storm water runoff to provide clean water. The treatment facility includes a pretreatment chamber for removing large toxic particles from the storm water runoff and absorbent chamber for removing fine particles of toxic metals from the storm water runoff. The absorption chamber has an absorption bed of three absorptive materials for removing the fine particles of toxic metals from the storm water runoff.
