Sadia swine manure lagoon treatment case study

The Problem
SADIA, a major integrated hog producer located in the Santa Catarina province of Brazil requested permission to conduct a test to determine the effectiveness of Nordevco Associates’ technology to improve conditions in their manure storage lagoon at a facility located in Concordia. Nordevco’s solution was applied by the producer and all testing and analyses were carried out jointly by EMBRAPA, the arm of the Brazilian Federal Government responsible for the research and development of new technologies and practices in the hog and poultry industries, and CNPSA, the National Center for Hog and Poultry Research.

Our Approach
BactiDomus Technology Bio4Swine was applied at a rate of .06 kgs/square meter of lagoon surface area (total surface area 144 m2) through the lagoon inflow pipe by farm staff on November 20, 1996. No changes were made to normal farm operations and the barn pits were cleaned and emptied into the lagoon on a regular basis during the treatment.

The Technology
Nordevco’s BactiDomus Technology was developed by a diversified group of research scientists working together at Universities in Belgium and France. Their goal was to create a mechanism with the flexibility to delivery biological solutions to a range of environmental issues more effectively and efficiently.

The foundation for the success of the BACTIDOMUS Technology was the development team’s clear understands that for any carrier material to be successful it had to meet specific underlying needs of the organisms:

  • Regardless of the organisms used, they would be cultured in a sterile laboratory and would require time to acclimate to the environment they were activated in.
  • Microorganisms, like humans, do not exist or thrive in isolation of each other but rather rely on others for stimulation and competition;
  • Organisms prefer to grow and live in colonies or flocs and prefer to attach to something to anchor these colonies;
  • Individual species of microorganisms do not work in isolation to break down organic compounds. To successfully break down any organic completely to CO2 and H20, a variety of different organisms are required;

The result of that work is the BactiDomus Technology which is based on the use of an inorganic limestone-like porous carrier material. The porosity of the material allows it to be bathed in a nutrient broth, absorbing key micro-nutrients that act as an initial food source when the product is activated. It is then impregnated with a range of different naturally occurring and non-pathogenic organisms, selected for their ability to breakdown specific organic contaminants.
