Choosing the right sewage treatment products is a crucial decision for homeowners and businesses alike. A properly selected and maintained system ensures effective wastewater management, protects the environment, and complies with local regulations[5]. This article will guide you through the various factors to consider when selecting sewage treatment products, comparing different systems, and offering practical advice for making the best choice for your specific needs.
Before diving into the selection process, it's essential to understand the basics of wastewater treatment. Wastewater, also known as sewage, contains various contaminants, including organic matter, pathogens, and nutrients[3]. The goal of sewage treatment is to remove these contaminants and produce effluent that can be safely discharged back into the environment[2].
A typical sewage treatment process involves several stages[3]:
1. Preliminary Treatment: This stage removes large debris and solids through screening and grit removal[3].
2. Primary Treatment: Primary treatment involves sedimentation, where solid particles settle to the bottom, forming sludge[3].
3. Secondary Treatment: This stage uses biological processes to remove dissolved organic matter. Common methods include activated sludge and trickling filters[3][7].
4. Advanced Treatment: This optional stage removes specific pollutants like nitrogen and phosphorus. Media filters and aerobic treatment units fall into this category[10].
5. Disinfection: The final stage disinfects the treated effluent to kill any remaining pathogens before discharge[3].
There are several types of sewage treatment systems available, each with its own advantages and disadvantages[5]. The choice of system depends on factors such as the size of the property, soil conditions, discharge requirements, and budget[5].
Septic tanks are one of the most common types of on-site wastewater treatment systems[5]. They consist of a buried, watertight container, typically made of concrete or plastic[10]. Wastewater flows into the tank, where solids settle to the bottom and scum floats to the top. The partially treated liquid effluent is then discharged to a drain field, where it filters through the soil[10].
Advantages:
- Simple and reliable[5].
- Relatively low cost[2].
- Minimal maintenance requirements.
Disadvantages:
- Requires a suitable drain field area[2].
- Can be ineffective in areas with poor soil conditions or high water tables[5].
- May not meet stringent discharge requirements[9].
Compact biofilters, such as the Ecoflo system, are advanced treatment systems that use a filter media to remove contaminants from wastewater[1]. These systems are designed to provide a higher level of treatment than septic tanks, making them suitable for properties with challenging site conditions or strict discharge limits[1].
Advantages:
- High treatment performance[1].
- Small footprint[2].
- Suitable for sensitive environments.
Disadvantages:
- Higher initial cost[2].
- Requires periodic media replacement.
Aerobic Treatment Units (ATUs) use air compressors or blowers to aerate wastewater, promoting the growth of aerobic bacteria that digest organic matter[10]. ATUs can achieve a high level of treatment and are often used in areas where septic tanks are not suitable[10].
Advantages:
- Excellent treatment efficiency[2].
- Can be used in areas with poor soil conditions[5].
- Reduces leach field footprint[2].
Disadvantages:
- Requires electricity to operate[2].
- More complex and costly than septic tanks[2].
- Needs regular maintenance.
Bionest systems are another type of advanced wastewater treatment technology that utilizes a fixed-film bioreactor to treat wastewater[1]. These systems are known for their compact design and effective treatment performance[1].
Advantages:
- Compact and easy to install[1].
- High treatment capacity.
Disadvantages:
- Can be expensive.
- May require professional maintenance.
Norweco Bio-Kinetic Systems are self-contained systems that use a robust aerator and bio-kinetic filter to provide consistent flow equalization, ensuring that all wastewater is fully treated[2]. These systems are designed to operate efficiently and automatically[2].
Advantages:
- Consistent flow equalization[2].
- Efficient and automatic operation[2].
- Minimal maintenance.
Disadvantages:
- Can be costly.
- Requires professional installation[2].
Selecting the right sewage treatment product requires careful consideration of several factors.
The characteristics of your property play a significant role in determining the most suitable system[5]. Consider the following:
- Soil Type: Soil composition affects the ability of the drain field to filter effluent[5].
- Lot Size: The available space will dictate the size and type of system you can install[2].
- Water Table: A high water table can interfere with the functioning of a septic system[5].
- Proximity to Water Bodies: If your property is near a lake or stream, you may need a more advanced treatment system to protect water quality[9].
The amount of wastewater your household or business generates is another critical factor. Systems are typically rated by their treatment capacity, measured in gallons per day (GPD)[3]. Make sure to choose a system that can handle your daily wastewater volume[3].
Local regulations and environmental standards dictate the level of treatment required for wastewater discharge[9]. Some areas may require advanced treatment systems to remove specific pollutants[6]. Check with your local health department or environmental agency to understand the specific requirements in your area[5].
The cost of a sewage treatment system includes the initial purchase price, installation fees, and ongoing maintenance expenses[2]. Septic tanks are generally the least expensive option, while advanced treatment systems can be more costly[2]. Consider the long-term costs and benefits of each system when making your decision[1].
All sewage treatment systems require regular maintenance to ensure proper functioning[2]. Septic tanks need to be pumped every few years to remove accumulated sludge[10]. Advanced treatment systems may require more frequent maintenance, such as filter cleaning or media replacement[1]. Factor in these maintenance requirements when comparing different systems[2].
Proper installation is crucial for the performance and longevity of a sewage treatment system[2]. It is best to have the system installed by a certified professional who is familiar with local regulations and best practices[2].
Before installing a sewage treatment system, you will likely need to obtain permits from your local health department or environmental agency[9]. The permitting process ensures that the system meets all applicable regulations and is properly designed for your site[5].

Choosing the right sewage treatment product is a significant investment that requires careful consideration of various factors. By understanding the different types of systems available, assessing your site conditions, and considering your treatment needs and budget, you can make an informed decision that will ensure effective wastewater management and protect the environment. Consulting with a qualified professional is always recommended to ensure the system is properly designed, installed, and maintained.
A septic tank is a simple system that provides primary treatment of wastewater, while a sewage treatment plant offers more advanced treatment through multiple stages, including secondary and sometimes tertiary treatment[10]. Sewage treatment plants generally produce a higher quality effluent and are suitable for areas with stricter discharge requirements[9].
A septic tank should typically be pumped every 3 to 5 years, depending on the size of the tank and the number of people in the household[10]. Regular pumping prevents the accumulation of solids, which can lead to system failure and environmental contamination[10].
Signs of a failing septic system include slow-draining toilets and sinks, foul odors in the yard, standing water or soggy areas near the drain field, and the presence of sewage backups in the home[5]. If you notice any of these signs, it is essential to have your system inspected and repaired as soon as possible[5].
While it may be tempting to install a sewage treatment system yourself to save money, it is generally not recommended[2]. Proper installation requires specialized knowledge and equipment, and improper installation can lead to system failure and environmental problems[2]. It is best to hire a certified professional who is familiar with local regulations and best practices[2].
To prolong the life of your sewage treatment system, follow these tips:
- Have your septic tank pumped regularly[10].
- Avoid flushing non-biodegradable items down the toilet[3].
- Conserve water to reduce the volume of wastewater entering the system[3].
- Keep the drain field free of trees and other vegetation[5].
- Avoid pouring grease, oil, and chemicals down the drain[3].
