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.
As organics are removed from the wastewater during the anaerobic digestion process, methane-rich biogas is produced
Anaerobic digestion produces very little excess sludge & with treatment the agriculturally-beneficial sludge can safely be applied to land as fertilizer

Tap into Renewable Energy from Biogas: As organics are removed from the wastewater during the anaerobic digestion process, methane-rich biogas is produced. This valuable biogas can be captured, treated, and used a source of renewable energy to displace fossil fuels or to generate heat or electricity.
Evoqua has extensive experience supplying complete biogas handling, treatment, and utilization systems for the recovery of renewable energy from wastewater and organic waste. We offer biogas technologies to assist with waste-to-energy initiatives to help treatment plants recover money-saving resources.
Minimize Sludge Production: Compared to aerobic treatment systems, anaerobic systems use substantially less energy, require fewer chemicals, and incur lower sludge handling costs. Anaerobic digestion produces very little excess sludge, and with treatmentbut the agriculturally-beneficial sludge can safely be applied to land as fertilizer.
