Introduction

When we flush our toilets or run the dishwasher, we often don’t think about what happens to the wastewater afterward. Yet, within this seemingly mundane process lies a critical environmental challenge: the removal of nitrogen. Nitrogen, a natural component of human waste, can wreak havoc on both the environment and public health if not properly managed. In this journey through the world of septic systems and nitrogen removal, we’ll explore the why, the how, and the significant impact it has on our lives. This article will explore – “Septic System Nitrogen Removal“.

The Nitrogen Conundrum

Nitrogen is an essential nutrient for plant life, but when it finds its way into wastewater, it becomes a formidable pollutant. This journey begins innocently enough – through inadequate treatment systems that discharge nitrogen compounds into the environment. From there, these compounds infiltrate groundwater and nearby watercourses, setting the stage for lasting environmental damage.

Groundwater contaminated with nitrate, a nitrogen compound, poses a serious threat to public health. Elevated nitrate concentrations in drinking water impede the blood’s ability to transport oxygen, a condition known as methemoglobinemia, or blue baby syndrome, particularly harmful to infants.

In lakes and rivers, an excess of nitrogen transforms these bodies of water into breeding grounds for rampant algae growth. These algae blooms obstruct sunlight, preventing it from reaching the submerged plants. As native species perish, bacteria that thrive on decomposing plant matter multiply, consuming oxygen until the water can no longer sustain life.

Septic System Nitrogen Removal: The High Cost of Nitrogen Contamination

The consequences of nitrogen contamination extend far beyond the initial environmental impact. From human health to economic repercussions, the toll is significant:

  1. Human Illnesses and Death: Nitrate-contaminated water poses health risks, especially to infants, potentially leading to severe conditions like blue baby syndrome.
  2. Livestock Poisoning: Agricultural runoff containing excess nitrogen can harm livestock, affecting both animal health and the food supply chain.
  3. Invasions of Non-Native Species: Nitrogen-rich environments facilitate the spread of non-native species, disrupting ecosystems and biodiversity.
  4. Reduced Biodiversity: Algae blooms, fueled by nitrogen, contribute to the decline of native species, upsetting the delicate balance of ecosystems.
  5. Toxins and Deformities in Fish: Nitrogen-induced algal blooms can produce toxins harmful to fish, affecting the seafood industry and the health of aquatic ecosystems.
  6. Reduced Waterfront Property Values: Nitrogen contamination can decrease the value of waterfront properties, impacting local economies.
  7. Limited Enjoyment of Lakes and Rivers: Excessive algae growth interferes with recreational activities such as swimming, boating, and fishing, diminishing the enjoyment of natural water bodies.
  8. Lost Revenues for Commercial Fisheries: The economic impact of nitrogen contamination extends to commercial fisheries, leading to lost revenues and livelihoods.

The Role of Septic Systems in Nitrogen Removal

In addressing the nitrogen challenge, it’s essential to understand that conventional anaerobic septic systems fall short. These systems, while effective in treating various pollutants, only remove a modest 30% of nitrogen from wastewater, leaving a substantial amount to infiltrate the environment.

Enter aerobic septic systems and In-Ground Nitrogen Removing Biofilters (INRB), often referred to as modified drain fields . These systems represent a leap forward in efficiency when it comes to nitrogen removal from wastewater. Unlike their anaerobic counterparts, these aerobic systems and biofilters tackle nitrogen head-on, offering a more comprehensive solution to this environmental dilemma.

Aerobic Septic Systems

Aerobic systems play a crucial role in effectively removing nitrogen from septic systems, offering several advantages over traditional anaerobic systems. Nitrogen, primarily in the form of ammonia, poses environmental concerns when released into water bodies, leading to issues like nutrient pollution and harm to aquatic ecosystems. Aerobic systems, which rely on oxygen-dependent microbial activity, excel in addressing these concerns.

One key advantage of aerobic systems is their enhanced nitrogen removal efficiency. The aerobic environment promotes the growth and activity of aerobic bacteria, which are more effective in converting ammonia into nitrate through the nitrification process. This is a two-step biological conversion that significantly reduces the nitrogen content in wastewater. Additionally, aerobic systems support denitrification, a process where specialized bacteria convert nitrate into nitrogen gas, which is released harmlessly into the atmosphere.

Furthermore, aerobic systems tend to have a higher treatment capacity compared to anaerobic systems. This increased capacity allows for better handling of larger volumes of wastewater and higher concentrations of nitrogen, making aerobic systems suitable for areas with higher population density or increased nitrogen loading.

The aerobic treatment process also produces less sludge and odors compared to anaerobic systems. This is advantageous in terms of maintenance and community acceptance. The reduced production of foul-smelling byproducts contributes to a more environmentally friendly and socially acceptable wastewater treatment solution.

In summary, the aerobic systems’ pros in removing nitrogen from septic systems include enhanced nitrogen removal efficiency, higher treatment capacity, and reduced sludge and odors, making them a more sustainable and effective choice for addressing nitrogen-related environmental concerns.

The INRB Advantage

In-Ground Nitrogen Removing Biofilters leverage aerobic processes, creating an environment where bacteria thrive in the presence of oxygen. This bacterial activity results in the breakdown of nitrogen compounds, converting them into harmless forms before the water is reintroduced into the environment.

Compared to conventional systems, INRBs boast a significantly higher nitrogen removal rate. These biofilters can effectively eliminate a more substantial percentage of nitrogen from wastewater, contributing to cleaner and safer water bodies.

Real-Life Impact

To grasp the significance of INRBs, consider the story of a community that made the switch. A lakeside town plagued by algae blooms and dwindling property values sought a sustainable solution. By adopting In-Ground Nitrogen Removing Biofilters, the community witnessed a remarkable transformation. Algae blooms diminished, the waterfront regained its natural beauty, and property values rebounded. Residents once again enjoyed the pristine lakeside environment without the looming threat of nitrogen-induced challenges.

Septic System Nitrogen Removal: FAQs

Nitrogen removal from sewage involves two crucial processes: nitrification and denitrification. In the first step, nitrification transforms ammonia in sewage into nitrite and then into nitrate through the activity of bacteria. Subsequently, denitrification occurs, where specialized bacteria convert nitrate into nitrogen gas, eliminating it from the wastewater. These dual processes, nitrification and denitrification, play a vital role in wastewater treatment, ensuring a more sustainable and environmentally friendly discharge.

Sewage contains nitrogen primarily due to human waste and the decomposition of organic matter. When we flush toilets or use drains, nitrogen from bodily excretions, detergents, and other organic materials enters the wastewater stream. Nitrogen compounds, particularly ammonia, result from the breakdown of proteins and urea in human waste. While nitrogen is a natural component of our bodies, managing its presence in sewage is crucial to prevent environmental and health hazards. Effective sewage treatment processes, including nitrification and denitrification, help mitigate the impact of nitrogen before discharge into the environment.
