Product Description
1.1 Technology introduction
The main function of the biogas slurry temporary storage system is to store the anaerobic digested biogas slurry. Can balance the fluctuation of the discharge volume of the front-end anaerobic fermentation tank and the processing volume of the back-end dehydration equipment. At the same time, it can serve as a secondary anaerobic digestion tank, which can continue to produce biogas and improve the overall economic benefits of the project.The temporary storage system for biogas slurry generally adopts the form of a tank, equipped with a central stirring device. The stirring force can fully mix the substances deposited at the bottom, floating at the top, and suspended substances. So that a relatively homogenous sludge is produced for the dewatering process.
Install a liquid level gauge on the temporary storage tank of biogas slurry to monitor the parameters inside the tank in real-time, ensuring safe operation.
- 1.2 Product Outstanding
- Secondary anaerobic digestion tank without heating equipment, relying on waste heat to continue digestion, can generate 5-15% more biogas
- Further degrade organic matter and reduce the pressure on subsequent sewage treatment facilities
- Adopting a tank form to avoid the risk of leakage in the tank form and reduce operational safety hazards
- Connect biogas to subsequent biogas treatment units to increase the total biogas production of the project
- Install high and low pressure protection devices to effectively prevent the danger caused by high or low pressure and protect the safety of the tank.

- Storage of anaerobic digested biogas slurry; It can also serve as a post anaerobic digestion tank.
- Like fermentation tanks, the materials and structural forms of biogas slurry tanks/post fermentation tanks currently mainly include Schumann tanks, Lipp tanks, enamel assembled tanks, and carbon steel welded anti-corrosion tanks.
