Biological treatment - Bioaugmentation - Bacteria addition

Most WWTP problems can be controlled with measures to minimize its origin in the drainage system. Thus, in some local drainage systems require special attention, for example the lift stations.

Bioaugmentation consists in an increase of selected bacteria that will help naturally the process of biological degradation of organic compounds.


This technology increases the capacity of existing microbial population in wastewater treatment systems. When organic compounds are degraded they are converted into H2O, CO2 and energy, which is used by the bacteria in their rapid process of multiplication.


This process has the following advantages:

  • Increases efficiency of the wastewater treatment system;
  • Reduces levels of BOD, COD, TSS and others;
  • Decomposes excess nutrients (ammonia, nitrites, nitrates and phosphates);
  • Liquefies and degrades organic matter with greater speed and efficiency;
  • Degrades fats and unwanted foams (FOGs);
  • Eliminate odors;
  • Reduces populations of pathogens;
  • Produces several types of enzymes;
  • It’s a solution of easy application.


Atlas Seis sells non-pathogenic biological products in liquid form, of natural origin, completely biodegradable.

BIODIGESTOR - Developed for wastewaters with increased organic matter and/or grease

FRAGRANCE - Neutralize odors


The bacteria used are not genetically engineered and are selected based on their ability to degrade certain products that are required to treat.


The reduction of parameters and odors through bioaugmentation is not an instantaneous process in which results immediately arise. The evolution of the results follows the process of implementation and growth of bacteria introduced in the system. As they assume predominance, they take control over the consumption of organic matter and begin to generate less offensive gaseous products. This is an ongoing process, limited by the evolution of bacteria and, therefore, it takes a few weeks to clearly see the results.


The intended effect of this technology is to help Nature to play its role because, in treatment systems, the conditions sometimes are not ideal.


The initial charge in the first applications will always be stronger, to ensure a good efficiency in the implementation of the bacteria in the system. Gradually, the quantities decrease until it reaches the dose of maintenance. The combination of appropriate strains with the appropriate dosage leads to highly cost-effective solutions.


The implementation of our bioaugmentation program is always based on a prior technical and specific analysis for each treatment system, which depends on the parameter being reduced and on the flow/volume being treated. Each system is unique so it is always important to do a global analysis of the treatment system and study possible oscillations.


Bioaugmentation is an economic solution, easy to implement, that rehabilitates the process of wastewater treatment.
