Water for irriga(on
Delhi AIWPS® Facility • Design Flow: 5.7 MLD
• Surface Area: 19 acres; Total Treatment Area: 29 acres (37°24’53”N, 120°45’12”W)
• Average TSS & BOD5 Removal: 90+%
• Average TN & TP Removal: 87% & 65%
• 6-‐log removal of E. coli (MPN/100mL)
• Complete methane fermenta(on in IPDs – NO SLUDGE
• 10x the oxygen transfer efficiency for 1/10th the energy use.
• More treatment for lowest capital, O&M and Life Cycle Costs.
