Selection parameters
The choice of biological treatment depends on many criteria.
To ensure high-quality wastewater treatment, it is essential to install a number of specialised wastewater treatment facilities. In particular, before using a biological filter, mechanical filtration is often required. Without this initial step, the efficiency of the biological filter decreases, making it unusable over time.
Combination with other installations
The MBBR system will not be viable if only a biological filter is used. Without mechanical filtration to remove particles, they accumulate on the media (bacterial supports). Heterotrophic (carbon consuming) bacteria will grow much faster than autotrophic (nitrogen purifying) bacteria.
With saturated cheaps, the action of the filtering bacteria will be much less effective. This failure will impact the development on their substrates.
AThus, the MBBR system will lose efficiency, eventually becoming inoperative. Hence, the importance of combining a drum filter with MBBR for optimal water circulation.
Activated process sludge
Activated sludge technology is a process for treating wastewater and industrial wastewater. Discovered at the beginning of the last century, this technology remains effective today.
Its design differs from other biological treatments, but the basic structure is similar:
- An aeration tank acts as a biological reactor.
- A settling tank separates solids, activated sludge, and treated water.
- A device returns activated sludge to the aeration tank, ensuring a continuous treatment cycle.
Oxygen requirement
To activate the bacteria and enable them to eliminate pollutants, certain conditions are essential. Oxygen is necessary for this process. Thus, aeration, whether through traditional air supply or a pure oxygen concentrate, is necessary.
The autotrophic bacteria will be able to carry out their metabolic function ensuring a quality filtration.
Depending on the amount of water to be purified, oxygen requirements can vary. Initial analysis is necessary to determine the oxygen needs of the system, ensuring optimal purification.
Bio-media
For optimal filtration, the media must be able to host a large number of bacteria. This requires certain characteristics, such as good porosity.
The porosity ensures smooth circulation, nourishing all bacteria for effective filtration.
Furthermore, the chosen material must promote anaerobic bacteria, which, without oxygen, convert nitrate into diazote. These bacteria play a key role in water purification.
Maintenance
The alert system monitors electrical components, water levels, and analyses. If a dysfunction happens, the audible and visual alarms provide localized notification. SCADA system will transmit alarms through Internet, generating email and/or text message notifications.
The routine maintenance of the entire system and the surrounding area includes:
- Daily cleaning
- Cleaning of the access uprisers, inlet grilles, and outlet filters.
The plastic material of the system makes maintenance easy. Furthermore, weeds must be controlled, and vegetation around the treatment system should be mowed.. Maintain the slope 3 inches below the top of the columns to ensure optimal performance.
Energy efficiency
Choosing an energy-efficient MBBR system is necessary. By saving on water and energy, you reduce your ecological footprint and achieve financial savings. It’s a beneficial choice for the planet and your budget.
To enhance energy efficiency, opt for a gravity-based system. This way, you will reduce excessive consumption related to the pumping of your water.
Used space
Optimizing energy efficiency and saving water reduces the space required. Less water means drier sludge, taking up less space. Thus, a smaller tank is sufficient to store these sludges. This compactness is one of the major advantages of MBBR technology.
The porosity of the media promotes the growth of more bacteria, providing a larger surface area of action.
Pressure loss
The head loss can affect the efficiency of your biological treatment, often due to temperature or climatic variations.
To remedy this, it is essential to use media resistant to these changes. Our activated carbon-based media is ideal for this. With its high porosity, it hosts a multitude of microorganisms.
Thus, it adapts to hydraulic and organic variations, meeting evolving standards and ensuring consistent performance.
