Biogas Plant (Constant Volume base) (SMT-BG-15)

This apparatus is designed to produce biogas through the anaerobic digestion of organic waste, converting materials like food scraps, manure, and vegetable matter into a renewable energy source primarily composed of methane. It serves as a functional system for demonstrating waste-to-energy conversion, yielding both usable biogas for heating or electricity and a nutrient-rich liquid fertilizer as a byproduct. The plant is a portable, integrated system featuring an 8.8 m³ digester tank and a 4.9 m³ gas holder. It includes a feeding unit with a mixer, pumps for material handling, and a comprehensive gas management system with scrubbing and moisture removal. Key components for monitoring and control are a level indicator, temperature gauges, pressure gauges, and flow control valves. The entire unit is thermally insulated to maintain optimal digestion temperatures. Its primary applications are in environmental engineering education and small-scale renewable energy projects, particularly for treating wastewater and agricultural waste. The key benefit is its ability to provide a hands-on, operational model of a circular economy process, allowing students to study anaerobic digestion parameters, manage gas production, and understand the practical aspects of sustainable waste management and biofuel generation.
