Improving a wastewater treatment plant with MBBR technology
The two-stage reed bed wastewater treatment plant was experiencing difficulties in ensuring effective nitrification. This situation posed a problem, as the facility was unable to achieve the required treatment levels for wastewater. To solve this issue, an MBBR nitrification module was added between the two existing stages. This module allowed for the capture of water filtered by the first stage, optimizing aeration and carbon treatment. Although nitrification efficiency significantly improved during summer, the drop in winter temperatures continued to pose challenges, despite overall compliance with current standards.

How to Improve Nitrification in a Reed Bed Wastewater Treatment Plant?
With strict treatment standards, the two-stage reed bed wastewater treatment plant needed to improve its nitrification. Our team installed an MBBR nitrification module between the two stages to address this issue. This system allowed for the capture of pre-filtered water, which improved aeration and carbon treatment. As a result, nitrification functioned better, especially in summer.
This installation requires the following elements:
- The flow rate varies between 400 and 800 PE.
- The module is installed between the two stages of the plant.
- The water temperature must remain above 12 degrees.
- Aeration is optimized to facilitate carbon treatment.
- Nitrogen treatment is improved, especially in summer.
- The plant complies with phosphorus discharge standards.
What is the Purpose of the MBBR Nitrification Module in a Reed Bed Wastewater Treatment Plant?
First, we install the MBBR module to improve nitrification in the treatment plant. Then, this module captures the filtered water from the first stage, which optimizes aeration and carbon treatment. By improving these processes, we promote nitrification, especially during summer months. Additionally, this system meets treatment standards by reducing phosphorus levels in discharges. Finally, it effectively manages flow and temperature variations, ensuring optimal wastewater treatment.
The MBBR Module: An Effective Solution for Improving Nitrification
To address this challenge, the solution incorporates an MBBR nitrification module between the two stages of the treatment plant. This system captures water already filtered by the first stage, thus optimizing aeration and carbon treatment. Moreover, the compact and efficient MBBR module promotes nitrification in summer when temperatures are adequate. By improving particle sedimentation, it allows for better contaminant removal. Coupled with an upstream treatment process, this system ensures optimal compliance with discharge standards, particularly for phosphorus and nitrogen.

Higher Nitrification Removal Rates Than Before
First, tests conducted after the installation of the MBBR module showed a significant improvement in nitrification, reaching over 90%. Next, these results confirm that the system meets the defined treatment objectives. Furthermore, this configuration effectively improves the degradation of organic matter, even with flow variations. It also ensures stable performance, adapted to the specific conditions of the plant. Finally, a major advantage is the low operating cost, which remains lower than that of other nitrification technologies.
To Successfully Improve Nitrification, 1h2o3 Carried Out:
- The installation of the MBBR module between the two stages of the treatment plant.
- The design of a solution adapted to the specific characteristics of the plant.
- The integration of necessary equipment to optimize aeration and carbon treatment.
- The commissioning of the system to ensure its optimal operation.
This integrated approach ensured an effective and coherent solution, meeting treatment objectives and environmental standards.
