Introduction

Aerobic septic systems are an effective and environmentally friendly way to treat wastewater. They rely on the presence of aerobic bacteria, which are bigger and more efficient at digesting organic matter compared to anaerobic bacteria. One common question that arises when it comes to aerobic septic systems is whether or not they require chlorine for proper functioning. In this article, we will explore the role of chlorine in aerobic septic systems and provide insights into its necessity.

How Do Aerobic Septic Systems Work?

Before diving into the topic of chlorine in aerobic septic systems, let’s briefly understand how these systems operate. Unlike traditional anaerobic septic systems, aerobic systems introduce oxygen into the treatment process. This oxygen promotes the growth of aerobic bacteria, which decompose the waste more effectively, resulting in cleaner effluent.

The process begins with the wastewater entering the aeration chamber, where air is continuously pumped to provide the necessary oxygen. In this chamber, aerobic bacteria digest the organic matter, converting it into less harmful substances. Once partially treated, the effluent flows into the clarifier, also known as the chlorinator.

Understanding The Clarifier Stage

In the clarifier stage of a septic system aeration, the partially treated effluent from the aeration chamber undergoes further treatment. This stage is crucial in removing any remaining pathogens, bacteria, or viruses that might still be present in the effluent. The clarifier, also known as the chlorinator, is where chlorine or UV light is employed to achieve this disinfection.

Disinfection With Chlorine

Chlorine is commonly used in aerobic septic systems as a disinfectant due to its effectiveness in killing microorganisms. It acts as a powerful oxidant, attacking and destroying bacteria, viruses, and other harmful pathogens. By using chlorine in the clarifier stage, the effluent is treated to ensure that it meets the necessary health and safety standards before being discharged.

Ultraviolet Light As An Alternative

In some aerobic septic systems, ultraviolet (UV) light is utilized as an alternative to chlorine for disinfection purposes. UV light works by damaging the genetic material of microorganisms, rendering them unable to reproduce and causing their destruction. UV disinfection can be a viable option for those who prefer to avoid the use of chemicals like chlorine in their septic systems.

Pump Chamber And Sprinkler System

Once the effluent is adequately disinfected in the clarifier, it flows into the pump chamber. From there, it is pumped to an above-ground sprinkler system, where it can be utilized for irrigation purposes. This process not only provides an environmentally friendly solution for wastewater disposal but also allows the effluent to be put to good use.

The Drain Field: Final Effluent Dispersal

In addition to the sprinkler system, the effluent can also be dispersed to the drain field, where it seeps into the ground. This serves as the final step in the treatment process, ensuring that any remaining contaminants are further filtered through the soil before reaching the groundwater.

Choosing The Right Chlorine Tablets

When it comes to selecting chlorine tablets for an aerobic septic system, it is essential to choose those approved by the Environmental Protection Agency (EPA). Calcium hypochlorite tablets are the recommended choice, as they are specifically formulated for wastewater treatment. These tablets dissolve more efficiently compared to swimming pool chlorine, ensuring proper disinfection of the effluent.

Chlorine vs. Swimming Pool Chlorine

It’s important to note that swimming pool chlorine is not suitable for wastewater treatment. Swimming pool chlorine products often contain trichloroisocyanuric acid, which dissolves slowly and is not an effective disinfectant for wastewater. Additionally, swimming pool chlorine tablets can release a gas called nitrogen chloride, which poses a high risk of explosion. Therefore, it is crucial to use specifically approved calcium hypochlorite tablets for aerobic septic systems.

Do Aerobic Septic Systems Need Chlorine: Proper Usage of Chlorine Tablets

To maintain optimal treatment performance, it is crucial to follow the recommended guidelines for chlorine tablet usage. On average, one to two chlorine tablets per week are typically sufficient, but the actual amount may vary depending on the septic system usage and load.

The Importance of Regular Maintenance

Maintaining an aerobic septic system is crucial to its long-term efficiency and effectiveness. Regular maintenance tasks, such as inspecting and cleaning system components, monitoring chlorine tablet levels, and addressing any issues promptly, help ensure that the system operates optimally. Engaging a professional septic system service provider for regular inspections and maintenance can provide peace of mind and extend the lifespan of the system.

Do Aerobic Septic Systems Need Chlorine: FAQs

In aerobic septic systems, specifically approved calcium hypochlorite tablets are commonly used as the source of chlorine. These tablets are formulated to dissolve efficiently and effectively disinfect the partially treated effluent in the clarifier or chlorinator stage of the system. Calcium hypochlorite tablets approved by the Environmental Protection Agency (EPA) are preferred over swimming pool chlorine due to their superior performance in wastewater treatment. By using the appropriate type of chlorine, aerobic septic systems can ensure the safe and efficient removal of pathogens and bacteria from the effluent.

In an aerobic septic system, chlorine is typically added through the access port to the chlorinator. The chlorinator, also known as the clarifier, is a crucial component where disinfection takes place. By accessing the chlorinator through the designated port, homeowners or professionals can add the approved calcium hypochlorite tablets directly into the system. This allows the chlorine to mix with the partially treated effluent, effectively killing any remaining pathogens and bacteria. Properly adding chlorine through the access port ensures that the aerobic septic system maintains its efficiency and provides safe wastewater treatment.

Using pool chlorine in a septic system is not recommended. Pool chlorine, which often contains trichloroisocyanuric acid, is not designed for wastewater treatment purposes. It dissolves slowly and may not effectively disinfect the effluent in a septic system. Moreover, pool chlorine tablets can release nitrogen chloride gas, posing a safety risk and potentially damaging septic system components. To ensure proper disinfection and safe operation of a septic system, it is important to use specifically approved calcium hypochlorite tablets, which are designed for wastewater treatment and dissolve efficiently, effectively killing pathogens and bacteria in the effluent.

Converting an anaerobic septic system to aerobic involves installing an aerobic treatment unit (ATU) or adding aeration components to the existing system. This modification introduces oxygen into the system, promoting the growth of beneficial aerobic bacteria that break down waste more efficiently.

Septic tank distribution box issues can disrupt your system. Problems include clogs from solid buildup, leading to uneven wastewater distribution among drain fields. Inadequate maintenance causes blockages and unpleasant odors. Damaged distribution pipes can also occur due to root intrusion or shifting soil. These problems hinder proper wastewater flow, potentially causing backups and groundwater contamination. Regular inspections, professional maintenance, and prompt repairs are vital to prevent distribution box problems, ensuring the septic system’s efficient operation and environmental safety.

Do Aerobic Septic Systems Need Chlorine: Conclusion

In conclusion, chlorine plays a crucial role in the final disinfection stage of aerobic septic systems. When using chlorine, it is important to opt for chlorine tablets that contain calcium hypochlorite, as they are approved by the Environmental Protection Agency for wastewater disinfection. Swimming pool chlorine, on the other hand, is not recommended for this purpose due to its slow dissolution and potential risks associated with the release of nitrogen chloride gas.

Proper usage of chlorine in aerobic septic systems is essential. It is recommended to follow the guidelines provided by professionals and manufacturers to ensure the correct dosage and frequency of chlorine tablet usage based on the septic system’s usage and requirements.

By maintaining the right balance between effective disinfection and environmental impact, aerobic septic systems can efficiently treat wastewater and contribute to a healthier and cleaner environment.
