The treatment of liquid organic waste—such as livestock effluent, biogas slurry, or food processing wastewater—has become an essential part of sustainable fertilizer manufacturing. Using an anaerobic fermentation tank or liquid fertilizer fermenter allows producers to convert waste into nutrient-rich liquid biofertilizer. But how can we make the fermentation process faster and more efficient?
1. Ensure Proper Raw Liquid Pre-treatment
Before entering the organic waste fermentation tank, liquid waste should be filtered or separated to remove large particles and sediment. A solid–liquid separator is usually installed before the tank to prevent clogging and create stable fermentation conditions. This step improves heat transfer inside the tank and allows microorganisms to decompose organic matter more effectively.
2. Maintain Stable Temperature and pH Inside the Fermentation System
In an anaerobic liquid fermentation reactor, microbial activity depends strongly on temperature and pH. Most anaerobic bacteria thrive between 35°C and 55°C. Installing a heating jacket or temperature control unit keeps the system within this range, accelerating the biochemical reactions.
Likewise, the pH level should stay neutral (around 7.0). Automatic sensors and pH regulators help maintain stability, avoiding acid inhibition that could slow fermentation.

3. Optimize Mixing and Gas Flow for Uniform Reaction
Continuous stirring ensures that microorganisms stay suspended and in contact with nutrients. Modern liquid fertilizer fermentation tanks are equipped with slow-speed agitators or gas circulation systems. These designs enhance contact between microbes and substrate while preventing sedimentation at the bottom.
Some large-scale systems also recover the biogas generated during the process, using it for heating or power generation.
4. Shorten Fermentation Time Through Automatic Control
The use of automation greatly influences fermentation efficiency. Sensors can track real-time data—temperature, gas production, oxidation-reduction potential—and automatically adjust parameters through PLC control.
Compared with traditional open pits, a sealed anaerobic fermentation vessel can reduce fermentation time by 30–50%, while keeping odors and contamination under control. Learn more!
5. Choose the Right Equipment Size and Material
Selecting a suitable liquid waste fermentation tank depends on the raw material type and production scale. Stainless steel or carbon steel tanks with anti-corrosion coatings are common for handling high-moisture, acidic substrates. For farms or biogas plants, modular tank systems are popular because they are easy to clean and expand when needed.
Conclusion
Accelerating liquid organic waste fermentation is not only about adding microbes—it’s about managing temperature, mixing, and control systems inside the anaerobic fermentation tank. With proper equipment and monitoring, producers can transform waste streams into valuable liquid biofertilizer in a shorter time and with greater environmental safety.
