Main raw and auxiliary materials

The main raw and auxiliary materials consumption of this 6t/h organic fertilizer processing plant in Tunisia project is shown in the table below.

Physical and chemical properties of raw and auxiliary materials:

Fermentation agent

The fermentation agent used in this project is a highly efficient composite microbial agent that can quickly decompose livestock and poultry manure, crop straw, sludge and organic waste from agricultural and sideline products.

It is a microbial preparation made of two or more non-antagonistic microbial strains. It can quickly decompose organic solid piles and is suitable for a variety of different compost substrates and different organic fertilizer turning equipment.

Domestic sludge

The domestic sludge purchased by this project mainly comes from public sewage treatment plants locally and surrounding cities that are used solely for treating urban domestic sewage. The sludge produced by these sewage treatment plants usually does not have hazardous characteristics and can be managed as general solid waste. Domestic sludge, about 50%-80%.

The moisture in the sludge and filter mud will evaporate during the fermentation process, and finally meet the product moisture index (moisture content ≤30%) requirements. Due to the evaporation loss of moisture in the mud, the total amount of sludge and other raw materials will be more than the product output to meet the production capacity requirements.

List of organic fertilizer processing equipment

The list of main equipment used in this 6t/h organic fertilizer processing plant in Tunisia project is shown in the table below.

Public works

Electrical engineering

The electricity for the project is provided by the municipal power supply network. The project does not have a boiler or standby generator.

Water supply

The water for the 6t/h organic fertilizer processing plant in Tunisia project comes from the municipal tap water network, mainly including water for the spray tower, laboratory and domestic water.

Drainage

The organic fertilizer pellet plant project implements rainwater and sewage diversion. Rainwater is collected and discharged into the municipal rainwater pipeline.

• Domestic sewage: The oily wastewater from the canteen is treated in the grease trap and then treated together with domestic sewage in the three-level septic tank. It is then treated by an integrated facility and reused for flushing the project site. It is not discharged.
• Laboratory wastewater: Instrument cleaning wastewater and pre-testing wastewater are hazardous wastes and are entrusted to relevant hazardous waste disposal units for treatment. The pure water machine prepares concentrated water for flushing the project site and is not discharged.
• Spray tower wastewater: It is recycled and only needs to be replenished with fresh water regularly. It is not discharged.

Process design of organic fertilizer processing plant in Tunisia

Brief description of organic fertilizer pellet process flow:

1. Feeding:
   The raw and auxiliary materials such as manure and sludge purchased by the 6t/h organic fertilizer processing plant in Tunisia project are relatively dry, with a water content of about 50%. After the raw materials are transported to the factory area by transport vehicles, they do not need to be stored and are immediately fed into the silo.
2. Mixing:
   After feeding, they are transported to the double-shaft mixer for mixing and mixing evenly.
3. Transport:
   The materials are transported to the distributor via a belt conveyor, and the distributor transports the materials to the fermentation tank.
4. Fermentation:
   The materials are transported to the fermentation tank via a belt conveyor for fermentation, and a fermentation agent (special strain) is added at the same time. No water is added during the fermentation and maturation process. The principle of aerobic microbial aerobic fermentation is adopted, so that the microorganisms use the organic matter, residual protein, etc. in the manure of poultry and livestock, and reproduce rapidly under a certain temperature, humidity and sufficient oxygen environment.
   During the reproduction process, they consume organic matter, protein and oxygen in the manure. The fermentation agent also has the function of rapidly degrading organic matter, while reducing the generation of odorous gases such as hydrogen sulfide and ammonia. Fermentation and maturation are all carried out in the fermentation tank, piled for fermentation, and the entire fermentation and maturation time is about 12-15 days.
   When white mycelium is produced in the pile, the material is loose and there is no original odor, it is a symbol of complete fermentation and maturation, and the fermented organic fertilizer material is obtained.
5. Turning:
   Turn and stir the raw materials during the fermentation process to make the raw materials evenly mixed. Generally, turn and stir once every two days to make them fully fermented.
6. Crushing:
   The fermented organic fertilizer material will have some lumps. After the organic waste material is conveyed to the entrance of the secondary aging area by the belt conveyor, the material (with some lumps) must be crushed first to make it loose.
7. Granulation:
   Process the crushed material into organic fertilizer pellets.
8. Screening:
   The prepared organic fertilizer granules are screened, and the sieved materials are returned for crushing, and the sieved materials meet the size requirements.
9. Packaging:
   Part of the sieved materials are transported to the packaging machine for packaging.
10. Finished products for sale:
    The packaged organic fertilizer is transported to the finished product area for sale.

Brief description of laboratory testing process:

1. Sample registration:
   The samples are sent from the production workshop to the laboratory, and the samples are registered according to the sample information and entered into the system.
2. Sample preparation:
   The samples mainly include powder samples, granular samples and liquid samples. The samples are processed to meet the test requirements.
3. Sample storage:
   The prepared samples are stored at room temperature or low temperature according to different storage conditions.
4. Sample pretreatment:
   The samples are first pretreated. The pretreatment process mainly includes weighing, dissolving, digesting, diluting and volume determination.
5. Sample detection experiment:
   The final injection vial is selected with a suitable detector for on-machine analysis. This process will produce laboratory gas, glassware washing wastewater, laboratory waste liquid, waste reagent bottles, and disposable laboratory consumables.
6. Data processing and result reporting:
   The data automatically generated by the instrument and equipment are processed and counted, and the final test results are archived.

What is the prospect of building organic fertilizer processing plant in Tunisia?

The prospects of building an organic fertilizer production line and processing organic fertilizer granules in Tunisia are relatively optimistic, but many factors need to be considered.

• First, the scale of Tunisia's fertilizer market is at an upper-middle level in Africa, and fertilizer consumption is mainly concentrated in phosphate and nitrogen fertilizers, which is closely related to the demand for the country's main crops such as wheat, barley and olives.
  With the improvement of global awareness of sustainable development and environmental protection, organic agriculture has gradually received attention, which provides development space for the organic fertilizer market.
• Secondly, in order to ensure national food security and promote sustainable agricultural development, the Tunisian government has continuously adjusted agricultural policies, including the supervision of fertilizer use. This has created favorable conditions for the market promotion and use of organic fertilizers.
  In addition, the application of precision agricultural technology has made the use of fertilizers more efficient and reduced the waste of resources, which has also provided a new growth point for the market demand for organic fertilizers.
• However, the Tunisian fertilizer market also faces some challenges. The demand for traditional fertilizers may be affected by the increase in environmental awareness, and economic factors such as fluctuations in agricultural product prices will also affect farmers' purchasing power for fertilizers.
  Therefore, companies processing organic fertilizer granules need to keep up with market trends and continuously innovate products and services to adapt to changing market demands.
