The ADF for the Carmelo Industrial Park facility has also been calculated by Steven Shih, R.E.H.S. of EHD in two of his Liquid Waste Inspection Forms for the subject EnviroServer. On 1212412001, i an ADF of 439 gpd was calculated based on the flow meter readings On 5/6/2002 an ADF flow volume of 342 gpd was calculated. F " C. INFLUENT AND EFFLUENT CHEMISTRY .. { The first sample obtained was effluent that had gone through the EnviroServer processing stages. The sample was taken from the pump chamber before it is pumped under pressure to the existing filter beds. A new, disposable Teflon bailer was lowered down into the chamber to sample the. effluent. This liquid was then transferred to a one-half liter plastic bottle without preservative. The second sample obtained was raw, septic influent satripled from the conventional septic tank near the southwest corner of the subject property. A new, disposable Teflon bailer was also used to sample influent from the second compartment; or pump chamber of this tank, before it is pumped northward to the EnviroServer for processing. . It is generally recognized that Total Nitrogen is the summation of ammonia-nitrogen (NH4) and organic nitrogen (proteins, amino acids, enzymes). Since the conventional septic tank is predominately anaerobic, nitrate normally does not exists"in the effluent. If nitrate existed in septic tank effluent, this would also be added to arrive at Total Nitrogen. Typically, 70-90% of the total ,- nitrogen in septic tank effluent is in the form of ammonium, while 10 to 30% is in the organic form. These percentages are reflected in the results of the effluent chemistry, as illustrated in Tables 1, below. In addition, concentrations of weak, medium and strong strength wastewaters have also been t presented°for comparison purposes from Wastewater Engineering, 3rd Ed., in;the three columns on the right of Table 1.
