Utilizing Different Anaerobic Digester System for Industries

Must read

Using an Anaerobic Digester System, we are actively attempting to purify industrial effluent. The amount of organic material in natural water bodies will also decrease by using various wastewater treatment technologies.  Process industrial waste is a tried-and-true, energy-efficient approach. Sewage sludge, wastewater, and industrial effluent are treated using anaerobic digestion, which is expanding very quickly. According to specialists, anaerobic digester systems are among the earliest methods of managing water waste. It produces biogas without consuming oxygen by employing anaerobic bacteria to break down organic contaminants or chemical oxygen demands. This technology offers minimal maintenance and efficient industrial power plants with a wide range of advantages.


During anaerobic digestion, microorganisms break down biodegradable materials without the use of oxygen. The process may involve a variety of microorganisms, including bacteria that produce acetic acid and archaea that produce methane. The necessary anaerobes Clostridium and Pseudomonas can only cause anaerobic digestion if oxygen inadvertently enters the system. As a result, acetogenic, acetobacter, and methanogenic bacteria can all contribute to anaerobic digestion.

An Overview Of Anaerobic Bacteria

Carbon, which is also a part of the carbon cycle, is a component of biodegradable materials. In India, anaerobic digestion is extremely popular. By producing methane through anaerobic digestion rather than using fossil fuels, we can lower greenhouse gas emissions. Anaerobic bacteria are employed to remediate wastewater treatment for industrial processes because they break down organic waste that would otherwise wind up in landfills or the ocean. It can utilise the anaerobic organisms’ digested excrement as a soil conditioner, which will also improve the nutrients in the soil. 


We concentrate on developing and putting into practice inexpensive, less-chemical solutions for industrial waste. By extracting methane from trash, anaerobic digesters help to lower greenhouse gas emissions. Construction and operation vary depending on the type of waste stream. WOG Group’s primary goal is to offer solutions for various water treatment and water management services. We try to use our natural resources responsibly, and one of those resources is water. Industrial wastewater treatment is a significant issue for enterprises.


Digesters Of Various Types

  • Passive Systems: With this technique, biogas is gathered under an impermeable cover with the help of a lagoon’s low maintenance needs. The most typical digester in a passive system is a covered lagoon. In a two-cell lagoon, the first cell is in complete closure, but the second cell is not. The liquid level in the first cell is constant to promote manure breakdown, but the liquid level in the second cell changes to produce storage. The temperatures of artificial lagoons exhibit seasonal trends.
  • Low-Rate Systems: Plug Flow Digesters and Complete Mix Digesters are two subtypes of low-rate systems. Liquids remain in the entire mix digestion for a total of 20 to 30 days in these digesters, maintaining the biogas production. By doing this, the entire batch of manure will store within a tank until it becomes liquid.
  • Systems with High Rates: High-rate systems have methane-producing microorganisms inside the anaerobic digester to boost efficiency. Complete mix digesters recycle the microbe-rich slurry back into the digester after using an external clarifier to separate the solids.

Managing Wastewater: Anaerobic Digestion’s Purpose

  • They frequently consider anaerobic digestion to be a secure method of wastewater treatment.
  • In order to be used as energy, sludge will transform into methane, the biogas made in the anaerobic digester.
  • Sewage from anaerobic digesters contains CH4, a valuable energy source for electricity production.
  • The construction of anaerobic digesters near residential areas increases local employment and tax revenue.
  • The quality of sludge will improve, and the adverse impacts on the nearby agricultural area will also reduce.
  • Treatment of organic waste in a sustainable manner has many positive effects on the environment.
  • Compost and animal manure also contribute to the creation of a less unpleasant fertiliser. It is easier for plants to absorb and contains less disease-causing chemicals.


An Anaerobic Digester’s Bacterial Decomposition Efficiency


The main advantages of this technology are the substantial space reductions, lower liquid effluent emissions, and large liquid resource savings. The anaerobic digester has the following advantages over the aerobic digester:

  • Numerous processes make use of anaerobic microbes. The anaerobic digester will consume almost minimal energy. 
  • The surface area of the reactor will shrink.
  • Industries will gradually use fewer chemicals.
  • After anaerobic treatment, aerobic treatment follows to make sure the water has been thoroughly fixed before being poured into a water channel.
  • The cost of sludge removal will inhibit the breakdown of microorganisms by anaerobic digesters.


Issues with Anaerobic Digestion

  • Using anaerobic digestion to create electricity from waste has the potential to be ecologically friendly and sustainable. It does, however, require careful preparation and effective organisation.
  • Small-scale operations may find it difficult to remain financially viable due to the expensive installation and operation of anaerobic digestion systems.
  • Technical difficulty: The anaerobic digester for process water treatment must be closely watched and managed to ensure that conditions are suitable for bacterial growth and methane production.
  • Anaerobic digestion can produce unpleasant odors and loud noises that can disturb nearby neighbours.
  • It’s possible that there will be conflicts with other land uses if crops or manure serve as fuel for anaerobic digestion. Examples include growing food or protecting the environment.

Countless Applications for Anaerobic Bacteria

WOG is conducting an extension work in order to assist the organization in moving forward with water recycling. In India, anaerobic digestion is in use for a variety of substrates, including sewage. Since they decompose organic waste that would otherwise end up in landfills or the ocean, anaerobic bacteria are used in industrial water treatment to purify the water. Biodegradable materials include carbon, which is also a component of the carbon cycle. We can reduce greenhouse gas emissions by creating methane through anaerobic digestion rather than burning fossil fuels. It can use the digested waste of the anaerobic organisms as a soil conditioner, which will also benefit the soil’s essential nutrients. In India, anaerobic digestion is extremely popular. 


We believe anaerobic digestion is the best option because it produces both methane and electrical energy when burned in a petrol engine. This is true since the use of ventilation during aerobic treatment necessitates the usage of electrical energy. Anaerobic digestion requires temperatures more than 25 °C, which are almost always present in India. A significant wastewater sludge management system will eventually include thickeners, digestion tanks, and sludge drying structures.  Wastewater treatment plants are available in different configurations for the benefit of the organization depending upon the type of waste the industry produces, we are working for environmental benefits. The main drawback of industrial waste is always upon the environmental surroundings.
