The science of wastewater treatment in Sunrise Beach and Camden County, MO is specific and critical to the safety of populations. Enviro-Line Co, Inc. understands the exceptional care that goes into creating an efficient, effective, reliable wastewater process. Our aim is to provide the products, services and general solutions necessary for you to maintain a well-functioning wastewater treatment operation.
Biological Nutrient Removal
Biological Nutrient Removal (BNR) takes place at a wastewater treatment plant in Camden County, MO. It’s the act of removing Nitrogen and Phosphorus from the waste stream prior to discharge or reuse of the water.
Nitrogen and Phosphorus are contributors to the lack of oxygen (hypoxia) in the Mississippi River, from point and non-point water sources. Since we only can control the point sources— wastewater treatment plant discharge—our focus is on ensuring a high quality of discharge water, below standards required by the Environmental Protection Agency (EPA) and local regulatory authorities. For example, water can discharge at the following levels for water quality:
| Level 1 | Level 2 | Level 3 | |
|---|---|---|---|
| BOD | < 10 ppm | < 5 ppm | < 3 ppm |
| TSS | < 10 ppm | < 5 ppm | < 3 ppm |
| Ammonia – N | < 1.5 ppm | < 1 ppm | < 0.5 ppm |
| Nitrate – N | < 6 ppm | < 4 ppm | < 2.5 ppm |
| Total Nitrogen | < 8 ppm | < 5 ppm | < 3 ppm |
| Phosphorus | < 1.5 ppm | < 0.5 ppm | < 0.3 ppm |
Stringent Quality Control
The more stringent the water quality, the more controls and other influences required for the treatment system design. For example, influent organic strength and water temperature will provide the necessary outside influences to performance effectiveness. The cleaner the water, the quicker the biological reactions. The more BOD organic strength (to a respectable level), the easier the denitrification and anaerobic requirements for BNR to occur.
The BNR process requirements include aerobic, anoxic and anaerobic zones, which allow biological ‘bugs’ to do their respective jobs.
| Aerobic Oxic | Anoxic | Anaerobic | |
|---|---|---|---|
| Oxygen | Provided | None Provided | None Provided |
| Mixing | Yes | Yes | Yes |
| BOD | Reduces | Reduces | Reduces |
| Ammonia | Reduces | Increases | Increases |
| Nitrate | Increases | Reduces | Reduces |
| Phosphorus | Adsorbed | Adsorbed | Released |
