Storage Post Fermentation Schumann Lipp Enamel Assembled Tanks

1.1 Technology introduction

• 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.
•                                    
• 1.3 Process parameters (kitchen waste)

• No.	Indicator	Unit	Value
  1	Inputs	t/d	100~1000t/d
  2	Slurry pH	--	7~9
  3	Content of solids	%	2~5
  4	Eta_VS	%	40~50
  5	Retention time	d	1~2
  6	Operating conditions		continuos
  7	Operating time	_	365d,24h/d

• 1.4 Fermentation liquid storage/secondary fermentation 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.
