Organic Fertilizer Production Plant-Design and Process
ORGANIC FERTILIZER PRODUCTION PLANT DESIGN AND PROCESS
1.Receiving Dehydrated Cake (sewage sludge)
Dehydrated cake and a large volume of compost that serves as an inoculum and a moisture adjusting medium are mixed in using a wheel loader. Thus, the optimum fermentation condition for microbial activity is prepared.
3. First Fermentation
Adjusted sewage mixture is evenly deposited using a wheel loader in the fermenter. Then, an appropriate amount of air for fermentation is supplied through the air duct from the blower located below the fermenter. In 4 to 5 days of fermentation, microorganisms decompose the organic matter, and allow for moisture evaporation and sterilization.
4. Second Fermentation (Curing Fermentation)
Using a wheel loader, the material that underwent the first fermentation and the recycled compost are mixed and the mixture is turned. When the optimum fermentation condition for microbial activity is ready, the mixture is evenly deposited in the fermenter and an appropriate amount of air is supplied through the air duct from the blower located below the fermenter. Fermentation continues for another 4 to 5 days for further organic matter decomposition, moisture evaporation and sterilization.
5. Third to Fifth Fermentation (Curing Fermentation)
