\nThe hydraulic management of a biogas plant is a crucial point: viscosity control is the key to an efficient plant and high yield<\/b>.\n<\/p>\n\n

\nPlant operators <\/b> have begun to use by-products and waste derived from agricultural, municipal, and agro-food industry activities for gas production, in order to reduce production costs or to comply with production regimes. Most of these wastes have a high fiber, cellulose, lignin, pectin, concentration which make them hard to be digest by bacteria. These components normally tend to float on the digester surface, creating crusts that compromise the plant hydraulic management. Generally, plant designers and operators tend to dilute the solid concentration in the digesters to compensate the inefficiency. Under this condition, the retention time increases and thus the digestate volume. It results in reduced plant efficiency and gas yield. Therefore, pretreatment systems are needed that enhance the use of these byproducts by improving their mixing in digesters and their production efficiency under standard plant retention times.\n<\/p>\n\n
