Can organic matter also cause ammonia nitrogen levels in water to exceed the permissible limit?

　　Organic compounds are also referred to as organic substances. They constitute the fundamental building blocks of life and are present in all living organisms. Aren’t organic substances essential elements for the human body? Then why do some people claim that organic matter can cause ammonia nitrogen levels in water to exceed regulatory limits?

　　In fact, it’s easy to see that in our daily lives, both food and other beneficial things should be consumed in moderation. Simply put, we should eat until we’re about seventy percent full, rather than overeating to the point of discomfort—because the latter is also harmful to our health.

　　Similarly, organic compounds present in the human body also have a safety threshold; exceeding this threshold can harm the body. So, can organic matter cause ammonia‑nitrogen levels to exceed the permissible limit?

　　Analysis indicates that, upon the influx of substantial carbon sources, denitrification cannot effectively utilize them. When these substrates enter the aeration tank, factors such as abundant carbon availability, heterotrophic oxygen consumption, high oxygen demand, and significant depletion of trace elements contribute to the dominance of nitrifying bacteria—autotrophic organisms with limited metabolic capacity—leading to intense competition for oxygen and the establishment of a dominant microbial community. Consequently, nitrification is constrained, resulting in an increase in ammonia‑nitrogen levels that exceeds regulatory limits.

　　Since organic matter can cause ammonia nitrogen levels in water to exceed regulatory limits, the next step is to address this issue. An online water-quality monitoring manufacturer will walk you through three potential solutions.

　　1. Immediately stop water inflow to prevent an explosion; keep both the interior and exterior continuously open.

　　II. Stop sludge thickening to ensure sludge concentration.

　　3. If organic matter causes bulking of non‑filamentous bacteria, PAC can be added to enhance floc formation, and an antifoaming agent can be used to eliminate foaming caused by shock loads.
