DEMON Nitrogen Removal Treatment System

World Water Works’ DEMON treatment system for removal of nitrogen from wastewater provides reliable performance and numerous benefits over traditional nitrification-denitrification systems, making it ideal for municipal and industrial clients that have wastewater streams with high ammonia concentrations.

A DEMON system can play an important role in wastewater treatment energy self-sufficiency, reducing costs, and optimizing any wastewater facility’s footprint. Other major benefits include reductions in ammonia load to the main treatment process, reduced sludge handling volumes, and less greenhouse gas production. More than thirty systems are currently operational using the patented DEMON technology, which was based on extensive academic, lab, field pilot, and full-scale experience.

The DEMON system features ammonia oxidizing bacteria (AOB), which convert half the ammonia to nitrite. A second anaerobic biological process uses Anammox bacteria to convert the combination of nitrite and remaining ammonia directly into nitrogen gas. This system reduces energy requirements by 60 percent, eliminates the need for all chemicals, and produces 90 percent less sludge. The system also features a low carbon footprint – the anaerobic process actually consumes carbon dioxide. The true key to the process success is the patented control strategy and patent pending biomass separation device that enriches the specialized slowly growing biomass. This enhances process robustness and treatment capacity.

    www RESOURCE DAF

    World Water Works, Inc. announces the availability of its new www/RESOURCE DAF, a next generation dissolved air flotation (DAF) system that handles flows from 5,000 to 8,000 gallons per minute (gpm) and is ideal for industries ranging from food processing, to desalination pretreatment, to textiles, to petroleum, and beyond. Pilot treatment plants are available and thorough bench testing and pilot treatability studies are conducted to guarantee results.

    With a high total dissolved solids (TDS) and saltwater tolerance, www/RESOURCE DAF provides the flexibility to outperform traditional DAFs and ensure longevity. Heavy duty durable polypropylene construction allows operation over a wide temperature range and pH range of 2-13, so the system offers tremendous treatment flexibility. The system’s design guarantees low operational and maintenance costs. Consistent and reliable performance ensures compliance with government regulations.

    The www/RESOURCE DAF system uses DAG (Dissolved Air Generator) technology, which allows the removal of fine insoluble materials by generating 5-12 micron bubbles, the finest in the industry. The DAG system achieves saturation efficiencies that approach 100 percent at low energy consumption. This performance has been documented through upgrades of existing systems that show the new DAG technology improves performance while reducing energy costs by more than 50 percent.
