Deferred Capital Expenditures through Increased Anaerobic Digester Capacity
MicroSludge speeds up the rate of anaerobic digestion to significantly lower the retention time needed for stable and effective anaerobic digestion. In addition, MicroSludge reduces the viscosity of thickened WAS, enabling TWAS with higher solids concentration to be fed to digesters, and to be pumped and mixed using a WWTP’s equipment that is already in place.
Together, faster digestion and thicker sludge fed to the digester provide the potential for large increases in digester throughput. Getting more digester capacity without building new digesters can save WWTPs large capital costs, on-going operating costs, and land requirements for plant expansion.
Reduced Disposal Fees by Less WAS for Disposal
MicroSludge liquefies WAS and this increases the rate and the extent that the biodegradable portion of WAS is anaerobically digested to biogas. The remaining solids that were not degraded are dewatered and sent for disposal. It is important to note that after MicroSludge processing, a portion of WAS solids will remain in solution and are processed with the liquid stream of the plant. Consequently, the overall reduction of residual sludge for disposal is due to both anaerobic digestion and WAS solubilization of the non-degradable portion of WAS. While the biodegradability and solubilization of WAS vary from plant to plant, MicroSludge helps to maximize the reduction of particulate solids of WAS to minimize residual sludge for disposal.

Increased Revenue from Renewable Energy Sales by Increased Biogas Production
MicroSludge increases the bioavailability of WAS for its anaerobic digestion to biogas. Although the anaerobic biodegradability of WAS varies from plant to plant, MicroSludge helps to increase both the rate and the amount of biogas that is produced from WAS.
Reduced Costs from a Reduced Load on Heat Exchangers for Digester Heating
Disrupting TWAS at 12,000 psi increases its temperature by 36 to 45F° (20 to 25C°). This MicroSludge process heat greatly reduces the external heat load needed to maintain anaerobic digester temperature.
Reduced Electrical Costs for Mixing and Pumping
MicroSludge greatly reduces the viscosity of TWAS. This lowers the electrical energy needed to pump sludge and mix digesters.
Lower Costs
Capital Costs: For wastewater treatment plants that need more anaerobic digestion capacity, MicroSludge provides an immediate payback by enabling digestion of thicker WAS and shorter digestion time. MicroSludge costs far less than building additional digesters.

Operating Costs: MicroSludge results in more biogas and less residual sludge for disposal. On-going savings are due to: reduced sludge disposal costs, more revenue or lower natural gas costs from increased biogas, and lower digester heating and mixing costs. Learn more...
