Description:
This study was conducted to evaluate the rapid infiltration (R.I.) method of land treatment as a partial solution to wastewater treatment and reuse for the 0.45 billion m3/yr (15.75 billion ft 3/yr) of safe irrigation water needed by the year 2000. hinese environmental scientists and water supply managers are considering the use of this technology for diluting high concentrations of itrate in the ground water while simultaneously recharging severely over-drafted aquifers. he wastewater used in this study contained synthetic organic compounds found on EPA's list of priority pollutants. uring the development of EPA's Land Treatment Design Manuals, research was terminated before a thorough evaluation of the treatability of these compounds could be completed. herefore, during this study, an evaluation of R.I. systems ability to treat selected priority pollutants.as well as fecal coliform bacteria was carried out in the interest of RSKERL's research objectives. ven though this research was focused on operations to optimize the removal of various nitrogen species from primary effluent, the normal wastewater parameters of BOD, COD, SS, Total - P, and TOC were also studied. he volatile organic compounds most prominent in the wastewater, dichloroethene, dichloroethane, chloroform and carbon tetrachloride were also evaluated for treatability in the cooperative study.
