S.K Euromarket - Anaerobic Digestion Systems In Bolted Tanks
Our anaerobic digestion plants are tailor made to the specific characteristics of the application. Their design is determined by:
- The type of incoming stream (solidwaste, feedstock manure, slaughterhouse residues)
- The capacity and feed rate of the of the incoming stream:
- The available space for installation
- Concrete tanks or bolted stainless steel circular reactors
- Feeding and discharge systems
- Internal mechanical mixers
- Heating system and thermal insulation for the reactor
- Biogas membrane holders
- Dehumidification system
- Desulphurization systems for biogas
- CHP unit cogeneration of heat and electric power
All components and pieces of equipment such as feeding and discharge units, controls, biogas membrane holders are sourced by reputable international manufacturers with whom we have long term partnerships.
Anaerobic digestion is a biological process that occurs naturally when bacteria break down organic matter in environments with little or no oxygen. In wastewater treatment processes, the breakdown of organic waste through anaerobic digestion is performed under controlled conditions in enclosed digesters. Almost any organic material can be processed with Anaerobic Digestion, including sewage, food waste, animal manure and other waste, industrial effluents, food leftovers etc
Advantages - Benefits of the Technology
Anaerobic digestion technology allows the conversion of waste into valuable energy and beneficial digestate in an all around environmentally friendly way.
There are two ways of seeing anaerobic digestion. The first is that of waste treatment and the second that of renewable energy production. Therefore, there are applications geared towards facilities that seek a treatment process for their waste and applications geared towards facilities focused on renewable energy production. Regardless of the original need, both application categories benefit from both waste reduction/consumption and energy - digestate production.Just to name a few, facilities that produce manure (from pigs, cattle or poultry), processing residues (from milk, dairy, brewery, oil or fish), municipal waste or food waste could successfully employ Anaerobic Digestion.
The digestion process takes place in a warmed, sealed airless container (the digester) which creates the ideal conditions for the bacteria to ferment the organic material in oxygen-free conditions. This digestion tank needs to be warmed and mixed thoroughly to create the ideal conditions for the bacteria to convert organic matter into biogas.
- acidogenesis - further broken down by acidogenic bacteria by into simpler molecules, volatile fatty acids (VFAs) occurs, producing ammonia, CO2 and hydrogen sulfide as byproducts.
- acetogenesis - the simple molecules from acidogenesis are further digested by bacteria called acetogens to produce CO2, hydrogen and mainly acetic acid.
- methanogenesis - methane, CO2 and water are produced by bacteria called methanogens.
