Gryphon Environmental’s Advanced Drying Technology dries residuals and biosolids waste streams so that the solid
residuals may be used as fuel or renewable materials. The economic and environmental impacts are both very attractive for Gryphon clients. Landfill of sludge with high water content is eliminated and renewable fuels, fertilizer, or fabrication components are produced. The result is the elimination of an Operating Costs and the liability of landfill, as well as the reduction in fossil fuels being utilized to generate power.
Gryphon technology is an industry-changer for both the waste water treatment and industrial biomass producers. With lower capital and operating costs, our technology is the first to expand the simple equation to a point that generates solids Return on Investment:
The Gryphon Dryer uses compressed, heated air injection into a vacuum that acts to simultaneously evaporate and physically remove interstitial and chemically-bound water from dewatered sludge. Units are designed as a closed-loop air system, meaning the air used during the process is dried and re-circulated to take advantage of existing heat and to reduce energy consumption. The Gryphon Dryer 10/40 (400 ft of drying surface area) is able to remove 40-50 tons of water daily. Yields range from 60% to 90% solids, depending on the operators selection on the touch screen interface and the speed of the dryer belt (cycle time of drying).
We have enabled a closed-loop air system that promotes the reuse of wasted energy and thus enhances efficiency. Within that closed-loop design, we have made the “bottleneck”, or point of highest resistance, the injection plate directly above the sludge being dried. This breakthrough enables us to use a continuous process to dry the sludge.
To put the first innovative aspect in more simplified terms, the cycle of air promotes pressurized air above the effluent, and a negative vacuum pressure below the sludge. What occurs within the sludge is BOTH a rapid heat transfer resulting in vaporization and increased air flow rates which result in the removal of air by force (mass transfer).
