Azienda agricola CAZZOLA<\/p>\n\n

Customer\u2019s successful application case that with BioBANG has succeeded in significantly\nreducing of product\u2019s viscosity in the digesters. This reduction allowed the customer to\nimplement a gradual change of daily feeding, reducing the cost and projecting a future\nplant\u2019s repowering towards biomethane production.<\/p>\n\n\"azienda\n

Description<\/h3>\n\n

\nThe \u201cAzienda agricola Cazzola\u201d<\/i> farm in recent years has given much importance to renewable energies, in particular in the AD sector. In total, 2 biogas plants were built in succession (the oldest in 2010, while the most recent in 2012), both producing 1MW\/h of electricity and 500 Nm³ \/h of biogas.\n<\/p>\n

\nThe plant on which BioBANG was installed is the most recently built, consisting of a hydrolysis tank, a primary digester and a secondary digester. During construction, the plant was designed to be fed mainly with corn silage and cattle slurry with 30 days of retention time on primary digester.\n<\/p>\n

Before BioBANG installation, the daily feeding was composed by 42 t\/d of corn silage and 10 t\/d of cattle manure.<\/p>\n\n

Customer decided to install BioBANG on the plant to achieved two important goals:\n

    \n
  1. Improve the product viscosity inside the hydrolysis tank in way to load a greater quantity of difficult biomass (more manure, triticale or ryegrass) without having troubles related to floating layers formation on digester\u2019s surface.<\/li>\n
  2. After the viscosity improvement, reduce corn silage quantities, gradually replacing it with cheaper biomass (cow manure with litter, triticale, wheat or ryegrass silage) in way to save the total daily feeding cost.\n<\/li>\n<\/ol>\n<\/p>\n

    BioBANG<\/span> was installed in transferring from the primary fermenter to the hydrolysis tank in October 2018. BioBANG<\/span> currently works 2 m³ \/h of product with an Energy Rate of 7.5 kW\/m³.<\/p>\n\n
