Proprietary Sludge Treatment Process
SludgePower™ is ClearCove’s proprietary sludge treatment (cleaning and enhancement) process, and a critical component in the delivery of ClearCove’s energy production and reduction leadership.
Why is Sludge Treatment Important?
Trash and grit can cause operational and maintenance problems for anaerobic digesters; the cleaning of which can represent a large expense to plant operators. Many conventional technologies do not incorporate this important functionality.
Fortunately for our customers, SludgePower™ does.
What Does SludgePower™ Do?
Removes trash, grit, plastics and other inorganics from the sludge prior to anaerobic digestion. This in turn reduces anaerobic digester operational and maintenance costs.
Releases encased organics to increase sludge organic concentration by 80-90% and enable increased biogas generation
Dewaters trash and grit solids cake to approximately 30-40% for disposal, reducing solids disposal costs and storage
Replaces other processes, such as DAF
How Does It Work?
The sludge enters through the center of a perforated circular screen, flowing horizontally. The solids greater than the size of the screen openings remain inside the screen. An auger rotates to clear the openings of the screen and form a solids cake of 30-40% of solids for disposal.
The conditioned liquid sludge flows through the screen and moves on to the anaerobic digester for renewable energy generation.
