Galli Engineering is a leader in Dry Digestion technology to treat organic wastes with varying composition such as the organic fraction of municipal solids waste. In addition, further attention on the relation between feedstock composition, organic loading rate, and mixing regimes is required for continuous dry anaerobic digestion systems. Dry Digestion technology is attractive for treatment of the organic fraction of municipal solid waste (OFMSW) and agricultural wastes (AW). Anaerobic Digestion (AD) is a series of biological processes in which micro organisms break down biodegradable waste in the absence of oxygen to produce renewable energy. Large amounts of waste, including livestock manure, municipal wastewater solids, food waste, industrial wastewater and residuals, fats, oils, grease, and various other organic waste streams avoid getting dumped into landfills. Once processed, this waste is converted into biogas which can be used as a fuel to generate electricity, or further processed into renewable natural gas and transportation fuel.
Anaerobic treatment is typically utilized to treat warm, high-strength industrial wastewater containing high concentrations of biodegradable organic matter. This energy-efficient process reliably removes biochemical oxygen demand (BOD), chemical oxygen demand (COD), and total suspended solids (TSS) from wastewater.
Anaerobic processes use substantially less energy, require less chemicals, and incur lower sludge handling costs compared to aerobic treatment options. In addition, the biogas produced in the anaerobic process is a source of renewable energy that can be used to displace fossil fuels such as oil or natural gas, or to generate electricity.
Doing so can also improve financial sustainability and competitiveness by increasing efficiency.
