Wastewater treatment plants often face significant challenges during colder months. Low temperatures can drastically reduce the efficiency of biological processes, particularly denitrification, leading to non-compliance with discharge standards. However, advancements in microbial solutions offer a robust answer. This article delves into how specialized aerobic denitrifying bacteria, when coupled with innovative reactor designs, can maintain high nitrogen removal rates even in challenging low-temperature environments.

Traditionally, denitrification relies on anaerobic bacteria converting nitrates into nitrogen gas. This process is sensitive to temperature, with performance dropping significantly below optimal ranges. The breakthrough lies in the development and application of domesticated aerobic denitrifying bacteria. These unique microorganisms possess the capability to perform denitrification under aerobic conditions, offering a distinct advantage in mixed or fluctuating oxygen environments commonly found in wastewater treatment reactors. As a leading supplier of such advanced biological agents, we understand the critical need for reliable performance year-round.

The effectiveness of these aerobic denitrifying bacteria is often amplified through synergistic action with traditional anaerobic denitrifiers. This symbiotic relationship is facilitated by the bacteria's ability to create favorable microenvironments within the treatment system. Through the secretion of extracellular polymeric substances (EPS), these microbes form larger, more stable sludge flocs. These flocs create internal anaerobic zones, allowing anaerobic denitrification to occur concurrently with aerobic processes. This internal synergy significantly boosts overall nitrogen removal efficiency, a key aspect we aim to deliver to our clients.

Research has shown that employing these advanced bacteria, particularly strains like Flavobacterium, alongside a well-designed reactor system, can lead to remarkable results. Systems integrating air-lift micro-pressure internal circulation can create the necessary alternating aerobic and anaerobic conditions, enriching and stimulating these beneficial bacteria. This leads to high removal rates for Chemical Oxygen Demand (COD), ammonia nitrogen (NH4+-N), total nitrogen (TN), and total phosphorus (TP), often exceeding 75% for TN even in cold conditions.
