    [Abstract]
     
    While wastewater treatment has focused on removing water pollutants, many of the pollutants are valuable resources if recovered in a useful form.  This presentation focuses on novel means to capture the energy value in “used waters,” including domestic wastewater.  New developments in anaerobic membrane biofilm reactors (to generate methane) and microbial electrochemical cells (to generate electrical power or hydrogen gas) now make it feasible to achieve energy-positive treatment of the BOD.  After recovery of the energy from used water, most of the N and P are released as inorganic forms that can be recovered for recycle to agriculture.  This talk will focus on P recovery, although many of the principle also apply for N.  An important take-home lesson is that traditional techniques for “P removal” will not work for P recovery.   P-recovery techniques that produce a product useful in agriculture include precipitation as struvite or hydroxyapatite and selective sorption to Fe-based sorbents.   This talk will introduce the new technologies and offer insights into their pros and cons.
