AMMONIA NITRIFICATION OVER A CARBONATE ALKALINITY SOURCE

摘要

The ammonia nitrification over a calcite slurry process and system may be used for treating an ammonia containing fluid. An influent fluid stream (12) may be introduced into an aerobic contact element (10) that may have a microbial population therein. A plurality of calcite particles (30) and oxygen may be introduced into the aerobic contact element (10). The contents of the aerobic contract element (10) may be mixed. The contents may be communicated to a separation element (18) to output a nitrified fluid stream overflow (14) and for recycled a collected calcite particle stream (16).
