Anaerobic treatments

The Anaerobic Treatment or Anaerobic Digestion is the process in which microorganisms decompose organic material, easily biodegradable in the absence of oxygen. This process generates different gases, among which the main ones are methane and CO2. This treatment occurs in controlled spaces or Biodigesters, where several factors have influence on their performance, among the temperature and pH of the biodegraded material stand out. The gases emitted are used as fuel.


This treatment can be summarized in four stages:

1.- Hydrolysis: Substances of long molecular chains (proteins, fats and carbohydrates), often undissolved, are transformed into dissolved compounds (amino acids, organic acids and sugars).

2.- Acidogenesis: Microorganisms that transform hydrolyzed substances into fatty acids of short chain.

3.- Acetogenesis: Process in which bacteria transform fatty acids into acetic acid.

4.- Methanogenesis: Final stage of digestion, the bacteria producing methane, use the intermediate products of the previous stages to convert them into methane, carbon dioxide and water. Methanogenesis is very sensitive to pH (s), high or low.

Aplicaciones Especiales del Vallés S.L. it is a company specialized in Anaerobic Treatments, has a staff with great knowledge in facilities, start-up, maintenance and advice, as well as knowledge of the different industries consuming  these systems. All of the above, allows us to better understand the needs of each client.

Due to its specialization, APLICACIONES has invested in the needs of our clients and we currently have agreements with various companies and an own accumulator of Granular Anaerobic Biomass (GAB) of approx. 600 m³.

This allows us to offer immediately a large amount of sludge, even if there is not availability in the market, like other types of services, supported by our experience and our daily attention to the needs of our clients.
