The delivery of this new type of high-rate bioreactor is part of the second<br\/>phase of Pohjois-Suomen Biokaasu Oy&#8217;s &#8220;Northern Circular Economy Ecosystem&#8221; project, for which the Ministry<br\/>of the Environment has granted a 65% investment subsidy<\/p>\n\n<p>The fourth-generation hybrid bioreactor incorporates technology further developed by Biometa Finland Oy, as well<br\/>as combined operating principles from previous generation solutions. This is presumably the world&#8217;s first<br\/>commercial CEGSB (Carrier Enhanced Granular Sludge Bed) bioreactor to be delivered in this size class. The<br\/>CEGSB technology is designed to efficiently reduce the chemical oxygen demand (COD) of incoming municipal<br\/>wastewater biologically, while simultaneously producing biogas under constantly changing process conditions. The<br\/>optimal placement for the reactor is therefore before the main wastewater treatment processes. This aims to both<br\/>enhance the efficiency of these processes and significantly increase the wastewater treatment plant&#8217;s own energy<br\/>production. Compared to commonly used biogas reactors worldwide, the physical size of the CEGSB bioreactor in<br\/>this case is estimated to be 250 times smaller for the same wastewater pretreatment capacity and efficiency. The<br\/>bioreactor will be delivered ready for operation during 2025. The goal is to begin piloting at the Ranua wastewater<br\/>treatment plant in early 2026 and to verify the technology&#8217;s functionality through long-term measurements in an<br\/>industrial environment. Mika Impi\u00f6 from Pohjois-Suomen Biokaasu Oy, Juha-Matti S\u00e4\u00e4skilahti from Ranua Infra<br\/>Oy, and Riitta Alin from Biometa Finland Oy state that it is great to jointly promote novel, domestic environmental<br\/>technology. This is seen as an innovation with significant international potential and the ability to improve the state<br\/>of the environment.<\/p>\n\n<p><a href=\"https:\/\/www.biometa.fi\/wp-content\/uploads\/2025\/08\/Press-release-11.8.2025.pdf\" target=\"_blank\" rel=\"noopener\">Press release can be read from here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Biometa Finland Oy will deliver a pilot-scale, fourth-generation hybrid bioreactor to Pohjois-Suomen Biokaasu Oyfor processing municipal wastewater.
