Nitrogen Removing Biofilters for Onsite Wastewater Treatment on Long Island: Current and Future Prospects
Recent research has demonstrated that the approximately 360,000 septic tank/leaching systems and cesspools that serve 74% of homes across Suffolk County have caused the concentrations of nitrogen in groundwater to rise by 50% since 1985. This nitrogen-enriched groundwater is flowing into sensitive coastal environments where it has contributed to toxic algal blooms, oxygen-deprived waters, the l...
متن کاملOn-site Wastewater Treatment – Polonite and Other Filter Materials for Removal of Metals, Nitrogen and Phosphorus
Bed filters using reactive materials are an emerging technology for on-site wastewater treatment. Chemical reactions transfer contaminants from the aqueous to the solid phase. Phosphorus is removed from domestic wastewater by sorption to filter materials, which can then be recycled to agriculture as fertilisers and soil amendments. This thesis presents long-term column and fieldscale studies of...
متن کاملModeling Nitrogen in On-site Wastewater Treatment Systems
State regulatory agencies set standards for minimum lot size for homes on onsite wastewater treatment systems (OWTS) based on the expected nitrogen (N) load to groundwater. However, the data to support these standards are sparse. In a recent field study on a clay soil, we developed a two-dimensional model for N treatment. Our objective was to use this model to predict the N treatment for 12 soi...
متن کاملFuzzy predictive control for nitrogen removal in biological wastewater treatment.
Whenever the carbon/nitrogen ratio of a domestic wastewater is too low, full denitrification is difficult to obtain and an additional source of organic carbon has to be provided. Since loading conditions may vary appreciably over the diurnal cycle, depending on the weather and sewage conditions, dosing should be controlled by an adaptive regulator to keep into account the time-varying process d...
