Model EU 200 - Biological Digestion of Animal Wastes


EU200 contains a specially formulated range of adapted, high performance aerobic and facultative anaerobic micro-organisms developed for use in the biological digestion of animal wastes. EU200 is a very concentrated product. As the bacteria are reactivated from their dry state and applied to manure, they mass produce at an enormous rate, thriving on the particles of manure.

  • Application to either aerobic or anaerobic storage systems.
  • Treatment of waste from dairy, beef, pig and poultry operations.
  • Production of a uniform slurry with no separation of solids and liquids. Straw and fibres remain in suspension.
  • Fixing of nitrogen as nitrites and nitrates for later release into the soil.
  • Control of odour through the degradation of contributing compounds including indole, skatole, ammonia and hydrogen Sulphide.

The microbes present in EU200 supersede those originally in the manure, because they are better adapted, and take control of the whole decomposition process. They change the nature of the odour causing compounds by process of hydrolysis and bio oxidation. As a result of these reactions the BOD and COD of the manure are considerably lowered and the odours reduced not only during storage but also when the manure is spread.

Manure is an important by-product on livestock farms and it’s decomposition is an important operation. In recent times many farmers, recognising the economic value of manure and it’s qualities as a soil conditioner and fertiliser, have changed from conventional handling methods to liquid or semi-liquid storage systems which provide better efficiency in handling and application. Whilst liquid and semi-liquid storage is efficient and functional, many farmers have encountered certain problems. These problems differ from system to system and can be listed as follows.

In a liquid or semi-liquid manure storage area, an anaerobic (lacking oxygen) situation prevails. Odours, however, are generally only a localised problem. The odour often becomes very severe when manure is stirred and transported on to areas to be cropped. Sometimes after spreading the smells longer on for days causing public discomfort and nuisance. In pig and poultry operations the levels of smell are significant not only close to the manure store but also around a large area. In confinement buildings, even with forced ventilation, odours emanating are strong enough to cause respiratory problems among the livestock. In addition to this many farmers are facing legal restraints due to pollution laws which are being more strictly enforced.

Solid Build-Up Problems
In liquid or semi-liquid storage the rate of decomposition of the organic material is lowered because the bacteria originally present in the manure die. The few anaerobic strains, which survive, are not normally adapted to decompose many organic compounds (such as antibiotics, etc) which are difficult to biodegrade. As a result solids build-up occurs, the heaviest components settling to the bottom and sides while the lighter materials rise to the top, making a crust of varying thickness. The solids get separated from the liquid in the storage facility and the material differs in consistency at different depths or layers. The crust can be broken down by agitation but the solids build up at the bottom or the sides pose a problem. Farmers spend many tractor hours, and a great deal of fuel to break the solids loose and get uniform pumpable slurry. This problem becomes more serious when bedding material such as straw is agitated, stirred or back-flushed to break up the solids build-up - the smells also increase. The problem is especially severe in the manure pits located in confinement buildings.

Loss of Nitrogen
During storage, as the decomposition process continues, a fairly high percentage of nitrogen is lost due to ammonia conversation and formation of gases, such as indole and skotole the nitrogen heterocycles, which are very rich in nitrogen. These gases constantly escape from the manure lowering the fertiliser value of the manure. Also a very high percentage of this important and valuable nutrient is lost during agitation and spreading on the fields. Since most of the nitrogen is in an unstable form the losses continue even if manure is injected or disked in after spreading,

In order to solve these problems, Bio-Systems Europe has developed a combination product - Bio-Systems EU200 that is designed to be effective in all the areas under discussion above.

EU200 is a highly concentrated biological product containing selected and adapted strains of bacteria and ancillary enzymes capable of initiating rapid biological action for positive control of odours and inorganic compounds. The bacteria in EU200 are dried by a special process and are easily reactivated by mixing with water and allowing a little time for rehydration. As these bacteria are added to the manure system they begin to multiply and act on the odour causing compounds of which many are produced during the decomposition process. They have been identified and grouped as alcohol’s, acids, amines, carbonyls, esters; gases such as carbon dioxide, methane, ammonia and hydrogen sulphide and those mentioned earlier i.e. indole and skatole. Of all these the most penetrating and offensive gases are ammonia and hydrogen sulphide. They are present not only in the fresh manure but are released during storage in both liquid and semi-liquid condition. The level of odour varies with the type of storage, length of storage and seasonal conditions.

The bacterial strains in EU200 supersede those originally in the manure, being better adapted, and take control of the whole decomposition process. They change the nature of the odour causing compounds by process of hydrolysis and bio-oxidation. As a result of these reactions the biochemical oxygen demand (BOD) and chemical oxygen demand (COD) of the manure are lowered drastically and the odours reduced not only during storage but also when the manure is spread. There is no need to inject the manure or to disk it immediately for odour control.

How it Liquefies Manure and Prevents Solid Build-Up
As the highly concentrated bacteria in EU200 are reactivated and applied to the manure, they multiply at a very high rate thriving on the manure. The particles of fibre, straw, grain, etc remain in suspension. This results in a uniform slurry with little separation of solids from liquids. The uniform consistency of the slurry minimises the need to agitate or to stir it at the time of transport from the storage tank, pit or the lagoon. This saves time and money spent on fuel to run ancillary equipment such as cutter pumps etc. It also reduces the loss of nitrogen during agitation, stirring and aeration and makes possible uniform application of well decomposed manure slurry to the fields.

Dosage and Applications

New operations
For dairy operations use 1kg of EU200 per month for 25 to 30 dairy beasts (usually producing around 600kg manure) if 100% of the manure they produce goes into the storage system. This product quantity is most effectively added weekly. Applications can take place after making slurry in the reception pit, in the gutters, through the floor slats, via the pumps or over the manure in the alleyways.

For beef, swine or poultry operations, the dose is 1kg EU200 for every 30m3 of manure produced per month. Here, too, regular weekly additions are most effective.

Existing operations
For severe solids build up or a heavy sludge deposit in the storage system, an initial or purge dose of 2kg EU200 for every 30m3 of solids is recommended. This should be a once only operation and applications continued by way of the regular dosing given above. This “shock” dose can be adjusted to the severity of the build up problem.
