With the price of energy on the rise, the need for biofuel storage is ever increasing. Preload prestressed concrete tanks provide the durability, flexibility, and safety to store liquid biofuels and biogases. Depending on the storage need, a Preload tank can be built to various height-to-diameter ratios with flat or dome roofs or open top. As with all our digester tanks, we can incorporate the necessary conical floors and mixing equipment utilized for the treatment of biofuels.
