ORGANIC FERTILIZER PRODUCTION PLANT DESIGN AND PROCESS

1.Receiving Dehydrated Cake (sewage sludge)

Dehydrated cake discharged from the sewage plants and business establishments is transported by dump truck to the material tank and stored.

2. Mixing-in

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)

When the second fermentation is completed, the compost can be used as fertilizer or a soil conditioner. Further turning and fermentation in the same manner as for the second fermentation will produce more mature fertilizer and soil conditioner. Therefore, at Pyramid the process is repeated up to the fifth fermentation.
6. Granulation
New Type Organic Fertilizer Granulator is used to granulate the compost fertilizer in granules.
7. SCREENING
rotary drum screen
8. PACKAGING
automatic packaging machine
