The Upflow Anaerobic Sludge Blanket (UASB) process, often referred to as Biopaq, is a highly efficient and cost-effective technology for treating high-strength organic wastewaters. Developed by Paques B.V., Biopaq utilizes a unique combination of anaerobic digestion and granular sludge to break down organic matter into methane and carbon dioxide, generating renewable energy and reducing pollution. This article explores the key aspects of Biopaq technology, its applications, and its key licensees, CBI Walker, Inc. (U.S.) and Biwater (U.K.).
Biopaq: How it Works
At the heart of the Biopaq process lies a reactor filled with a special type of granular sludge. This sludge, composed of tightly packed microorganisms, forms a dense, stable blanket at the bottom of the reactor. Wastewater is introduced from the bottom, flowing upwards through the sludge bed. As the wastewater ascends, the anaerobic bacteria within the granules break down the organic matter through a series of complex biochemical reactions, producing biogas (primarily methane) and reducing the organic load.
