Overview
Anaerobic digesters are an essential component of wastewater treatment in municipal facilities. They break down organic matter in sludge, producing biogas and reducing the volume of waste. Maintaining consistent temperatures in anaerobic digesters is critical for supporting the digestion process’s microbial activity.
Direct Steam Injection (DSI) heaters offer numerous benefits in sludge heating in anaerobic digesters:
- Optimized digestion speed and biogas production without the need for pre-heating
- Near 100% thermal efficiency reduces energy use and operational costs
- Consistent temperature control boosts microbial activity, increasing biogas output and enhancing renewable energy generation
- Minimal fouling and scaling reduce downtime and maintenance
- Space-saving design integrates easily into systems and adapts to variable feedstocks, ensuring consistent performance
Solaris®
Solaris® heater offers a straight through design with low-shear flow, perfect for heavy slurries with medium consistency or higher solid contents. The diffuser injects steam across the entire cross-section to ensure thorough mixing and a uniform temperature even at a high volume and flow rate.
- Volume capability: 5 up to 25,000 gpm [1 up to 5,678 m³/hr]
NOH™ (Non-Obstructing Heater)
Non-Obstructing Heater™ (NOH) is rugged enough to handle even the toughest abrasive materials, like sand and grit, to fibrous materials and large particulates. Its flow-through design protects against plugging, fouling, and pressure drops with its unrestricted flow.
- Volume capability: 30 up to 3,035 gpm [6.8 up to 689 m³/hr]
