Design Procedure

The process design procedure for a typical SAT system is outlined in Table 8.20. If the hydraulic pathway is toward surface water, the limiting design factor will be related to surface water quality requirements, which could range from BOD and TSS to nutrients and trace organics. Groundwater discharges are more often controlled by pathogen and nitrate requirements. If nitrogen removal is a process design consideration, the following six steps should also be followed after the annual hydraulic loading is calculated (step 6); if necessary, steps 5 and 6 may be repeated for different levels of preapplication treatment to achieve the required level of overall treatment:
