Municipalities can use MBBR technology to achieve biological treatment of wastewater and drinking water.

Thanks to this technology, it is possible to treat wastewater. This equipment can therefore be easily incorporated into a water treatment plant. It will remove organic or nitrogenous compounds such as ammonium or nitrate.

Targeted sectors

Pulp and paper industry

The pulp and paper industry is one of the most water-intensive industries. It is important to note that the wastewater from these industries contains, among others:
  • suspended solids (SS)
  • chemical oxygen demand (COD)
  • chemical oxygen demand (COD)
  • traces of heavy metals
  • several persistent chlorinated organic compounds
  • bacteria

Food and beverage industry

This sector is not excluded from the range in which 1h2o3’s MBBR technology can be used. Whether it is for the manufacture of food or drink, water is essential.

If you look at a typical week in a food and beverage company, you can clearly see the use of massive amounts of water. This large amount of water also results in large amounts of wastewater!

When sending this water to a natural water source (lake, river), it must first be treated by an MBBR system. However, before it can be treated by this technology, the sludge must be separated from the rest of the process.


Wastewater from industrial slaughterhouses is characterized by its high emission of organic matter.

In addition, slaughterhouses produce large amounts of wastewater due to the slaughter process and the cleaning of the facilities.

Biological treatment of slaughterhouse wastewater is carried out with different methods including:

  • biological systems in aerobic environment
  • biological systems in anaerobic environment

According to the FAO, more than 10,000 kilos of meat are consumed every second in the world, or 323 million tons for the year 2017. This consumption has increased by 2.3% per year over the last 10 years. Average meat consumption per capita in the world is estimated at 42.9 kg/inhabitant.

Chemical effluent treatment from textile mills

The textile industry is also one of the most polluting sectors.

Indeed, the wastewater from these industries contains coloring particles and various man-made chemicals. They release huge amounts of highly polluted water into the environment. As a result, the photosynthetic activity of aquatic plants and animals is disrupted.

What are the MBBR facilities for wastewater treatment?

The advantages of using biological treatment for tertiary treatment

The MBBR will have its full role to play in wastewater purification. Actually, this biological filtration will remove any form of nitrate or CO2 in excess, which could pollute the water. If such concentrations were released directly into the water, without even being treated, it could lead to a real ecological disaster. Certainly, releasing highly nitrified water into a river or lake would lead to an eutrophication of the environment which would be conducive to the proliferation of plant species that would quickly become too important and would inevitably lead to an anoxia of the environment (because the plants will absorb all the O2 during their development, but especially during their decomposition)

As a result, the species in this habitat will no longer have access to this oxygen and will all eventually die.

Therefore, it is easy to understand the need for this process in the treatment of wastewater

What are the three wastewater treatment steps?

The three stages of wastewater treatment are essentially composed of the treatment :

  • primary
  • secondary
  • tertiary

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.

Primary treatment

During primary treatment, wastewater is temporarily held in a large settling tank where heavy solids settle to the bottom while lighter solids float to the surface.

After settling, the remaining liquid will hold these elements and will be discharged or conveyed to the more advanced secondary phase of wastewater treatment.

In addition, these large tanks often have built-in mechanical scrapers that continuously draw the sludge collected at the base of the tank to a pump that delivers it to a sludge treatment facility.

Secondary treatment

Compared to primary treatment, secondary wastewater treatment is intended to break down bacteria through aerobic biological processes.

Secondary wastewater treatment is completed, resulting in a safer discharge into the local environment by reducing common biodegradable contaminants to safe levels.

There are several methods that can be used in secondary treatment:

  • The use of
      • bioreactors
      • filter beds
      • aerated ponds
  • Activated mud
  • Application of rotating biological contactors

Tertiary treatment

Tertiary treatment is the final phase of wastewater treatment. It consists of disinfecting water from bacteria that could contaminate drinking water by respecting strict standards already established. This is a very important step to obtain drinking water used in homes or in industry. The treatment is carried out by two types of methods:
  • UV disinfection
  • Chemical disinfection
