The average total nitrogen concentration <br /> of domestic waste water is normally considered to by 20-85 mg/L-N (Crites and Tchobanoglous, <br /> 1998). For the purposes of the nitrate loading estimate, the long-term average concentration for <br /> total nitrogen in residential waste water is estimated to be approximately 45 mg/L-N and the <br /> long-term average concentration for total nitrogen in employee and customer waste water is 65 <br /> mg/L-N.
