Both overland flow and media filtration systems have the potential for partial treatment of high strength wastewater without contributing to odor concerns. The overland flow system is a low-intensity system requiring relatively little technical lknowledge or equipment to remove large amounts of N per unit area (up to 4 kg N/ha/day) through nitrification and partial denitrification. The media filtration system is a medium-intensity system which can nitrify up to 57% of the incoming NH3-N at a TN loading rate of 249 g/m**3/day. However, it requires additional equipment and operational oversight. The incorporation of these unit processes into an overall waste treatment system and their long-term performance must still be evaluated. |
