• SlurryCarb™

The SlurryCarb™ technology is a biosolids recycling solution as well as an opportunity to protect our environment by replacing fossil fuel consumption with a renewable energy source. Biosolids at up to 30% solids content are brought to a central manufacturing facility where they are processed as a pumpable slurry, creating savings in capital and operating costs. The biosolids slurry is continuously pumped and pressurized above its saturated steam pressure to maintain a liquid state throughout processing. By avoiding evaporation, thermal energy inputs for the evaporation of water are minimized. As a result, the SlurryCarb™ process requires approximately two-thirds less energy than traditional drying methods.

Upon reaching the desired reaction pressure and temperature, the biosolids undergo a molecular reconfiguration. The cellular structure of the biosolids ruptures and carbon dioxide gas splits off, a step called "carbonization." This reaction significantly reduces the size and improves the uniformity of the biosolids molecules. The reacted product becomes hydrophobic and can be mechanically dewatered to greater than 50% solids. This dewatered, reacted product is concentrated in carbon, and over 80% of the original water present in the biosolids is removed without evaporation.

The reacted, dewatered product is dried to form a fuel that has a heating value of approximately 7,000 Btu/lb. This fuel, called E-Fuel, is exported to a customer and utilized as a renewable fuel.

The need for environmentally and economically sound alternatives to traditional biosolids recycling methods is becoming increasingly evident. EnerTech's technology offers a low-cost, sustainable, and environmentally-friendly solution that has already gained the company widespread interest and support for its SlurryCarb™ process.
