Cities can adopt MBBR technology to effectively treat wastewater and drinking water.
This technology allows for the treatment of wastewater. This equipment can easily be incorporated into a water treatment station. It will remove organic or nitrogenous compounds such as ammonium or nitrate.
Pulp and paper industry
The pulp and paper industry is among those that have the greatest need for water.
We must note that wastewater from these industries contains, among other things:
- suspended solids (SS)
- chemical oxygen demand (COD)
- chemical oxygen demand (COD)
- traces of heavy metals
- several persistent chlorinated organic compounds
Food and beverage industry
The food industry uses a significant amount of water; the 1h2o3 MBBR technology is essential for its management. Whether it’s for producing food or beverages, water is at the heart of the process.
Think about a typical week in such a business: water usage is colossal. And where there is high water consumption, there is also a significant amount of wastewater to be treated. It is therefore essential to have effective solutions for managing these waters.
Before discharge into the natural environment, treat the water with MBBR to purify it. However, the sludge must first be separated from the rest of the process for effective treatment
Containing a significant quantity of organic matter, wastewater from industrial slaughterhouses requires specific and rigorous treatment. The slaughtering and cleaning stages generate these waters in large quantities, posing a significant challenge.
We implement various biological treatment methods, all tailored to the specificities of wastewater from industrial slaughterhouses:
- biological systems in aerobic environment
- biological systems in anaerobic environment
According to the FAO, the world consumes over 10,000 kilograms of meat every second, totaling 323 million tonnes in 2017. This consumption has increased by 2.3% annually over the past 10 years.” On average, each person worldwide consumes approximately 42.9 kg of meat per year.
Chemical effluent treatment from textile mills
The textile industry is also one of the most polluting sectors.
The textile industry is one of the most polluting. The wastewater from these factories contains chemicals and dyes. They discharge significant amounts of highly polluted water, harming aquatic life.
The advantages of using biological treatment for tertiary treatment
The MBBR treats water by removing excess nitrate and CO2, preventing potential pollution and playing a key role. If these concentrations were released without treatment, it would cause an ecological disaster. Releasing water rich in nitrates into a river or lake causes eutrophication, promoting excessive plant growth. This abundance can lead to an oxygen loss, harmful to the ecosystem.
As a result, the species in this habitat will no longer have access to this oxygen and will all eventually die.
It’s easy to see why this process is so important for wastewater treatment.
What are the three wastewater treatment steps?
Primary, secondary, and tertiary treatment essentially constitute the three stages of wastewater treatment.
Each step represents a higher level of purification. It is not required in some applications and depends :
- the intended use of water
- the environment into which it will be discharged.
A large settling basin stores wastewater during primary treatment, allowing for the separation of solids. Heavy solids settle at the bottom, while light solids float on the surface, facilitating their separation.
The liquid remaining after the settling process captures certain elements, requiring special attention for the next steps. Next, the liquid is either discharged or sent to the secondary phase for further treatment of wastewater.
Moreover, these large tanks are often equipped with mechanical scrapers, ensuring the effective removal of deposited sludge. These scrapers continuously gather sludge at the bottom of the tank, facilitating its collection for treatment. A pump receives the collected sludge and sends it to specific facilities, ensuring its proper and secure treatment.
The secondary treatment of wastewater utilizes biological methods to eliminate bacteria. After this treatment, the water is cleaner and can be safely discharged into the environment.
There are several methods that can be used in secondary treatment:
- The use of
- filter beds
- aerated ponds
- Activated mud
- Application of rotating biological contactors
Tertiary treatment ensures that the treated water is clean and safe for consumption, representing a crucial final step in this process. It aims to eliminate bacteria that pose a threat to water potability while adhering to strict safety standards.
The treatment is carried out by two types of methods:
- UV disinfection
- Chemical disinfection
