![]() ![]() ![]() ![]() Hi, Don't give up. Many of us have faced the same problem before: http://forum.hksaltfish.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=3;t=001739 I did not say a open system never work, it only takes more time and is not as efficient as a closed system. "It can be seen that nitrate reduction is more efficient in anaerobic batch systems than that in aerobic batch systems.......One possible reason is dissolved oxygen in anaerobic batch systems is much lower than that in aerobic batch systems so that the autotrophic denitrification process is well protected." Quote from page 12 of the attached report. ![]() |
