Abstract
The control of nutrients, principally nitrogen (N) and phosphorus, in liquid piggery wastes is becoming a significant issue for the Australian pig industry. A study by Payne (1990) found that the common waste treatment practice of ponding was highly effective at removing phosphorus from the liquid phase (averaging 92% removal), however, N was less effectively removed (46%). With this finding in mind, a technique has been developed to enhance nitrogen removal from ponding systems.
