The demand for sustainable and efficient wastewater treatment solutions is increasing globally. Traditional methods often struggle to effectively remove nutrients like nitrogen and phosphorus, leading to environmental damage. Enter Sequox, a revolutionary technology developed by Waterlink/Aero-Mod Systems, which utilizes a unique biological process to achieve comprehensive nutrient removal.
Sequox is a sequencing batch reactor (SBR) system that leverages a series of distinct phases to optimize biological activity. This approach allows for enhanced nutrient removal and efficient wastewater treatment. Here's a breakdown of the process:
1. Fill Phase: Wastewater is introduced into the reactor tank, initiating the first phase. During this phase, the wastewater is mixed with previously activated biomass, providing a suitable environment for microorganisms to thrive.
2. React Phase: This crucial stage focuses on biological nutrient removal. The reactor is aerated, allowing aerobic bacteria to consume organic matter and convert ammonia into nitrite and then nitrate. Subsequently, denitrifying bacteria utilize the nitrate as an electron acceptor, converting it into nitrogen gas, effectively removing it from the wastewater.
3. Settle Phase: Once the biological reactions have reached completion, the reactor is allowed to settle. This allows the biomass to settle at the bottom, separating it from the treated water.
4. Decant Phase: The clarified treated water is then discharged from the reactor, leaving behind the concentrated biomass.
5. Waste Phase: A portion of the concentrated biomass is removed to prevent overgrowth and maintain optimal system performance.
