Application Period

A range of application periods has been used successfully, with 6 to 12 hr/d being most common. A typical application period is 8 hr/d. With an 8-hr/d application period, the total field area is divided into three sections. The application period can then be increased to 12 hr/d for grass harvest or system maintenance. The application period can be increased to 24 hr/d for a short time (3 to 5 d) without adverse impacts on BOD or TSS performance; however, ammonia and trace metals may be released.
