The cell membranes of microbes in waste activated sludge (WAS) are extremely resilient, limiting how fast they breakdown to biogas in anaerobic digesters. MicroSludge effectively destroys the membranes of WAS microbes without destroying the enzymatic proteins in the cell's cytoplasm. The scanning electron microscope (SEM) images below show WAS before and after MicroSludge.
The SEM image above shows intact bacterial microbes magnified 20,000 times. The image below shows the same microbes following MicroSludge.
The above SEM shows that the cell membranes of WAS have been ruptured by MicroSludge. The liquid cellular contents (the “cytoplasm”) have been released, ready for digestion. This allows anaerobic digesters to improve performance.
Typically, 20 – 30% of WAS is converted to biogas in anaerobic digesters. With MicroSludge, generally 60% of WAS is converted into biogas. The extent of digester performance improvement with MicroSludge depends on many factors.
