MicroSludge unlocks the renewable energy potential of wastewater sludge, allowing anaerobic digesters to generate more biomethane faster and more efficiently.

At many industrial and municipal wastewater treatment plants, waste activated sludge is produced in large quantities and must be disposed of at significant cost. Sludge pre-treatment with MicroSludge enables the conversion of this waste stream into biogas as an economically viable alternative source of energy.

Generating renewable energy from waste meets many social, environmental and government objectives including: energy security, the reduction of greenhouse gas emissions and reducing the cost of wastewater treatment for both industrial and municipal plants.

Waste activated sludge (WAS) is a largely untapped source of renewable energy with a minimal carbon footprint. MicroSludge increases the production of green biogas from WAS that can displace energy produced from fossil sources.

Green biogas energy produced can be used on-site to reduce operating costs or can be sold to electric or gas utilities to provide a sustainable revenue stream.

Without sludge pre-treatment, the full potential of biogas energy cannot be achieved.

Incentives for Green Electricity and Green Biomethane

To encourage diversification of electrical power from the grid towards green energy, many governments offer economic incentives to produce electricity from renewable sources.  This includes co-generation of electricity from biogas.

Green energy incentives vary, but are typically offered on a per kWh basis and may do not require that the generated electricity be fed back to the grid. Consequently, WWTPs that employ anaerobic digestion of sludge to fuel co-generation engines can purchase electricity at the lower grid price and receive substantial green energy credits or feed-in tariffs. 

In certain jurisdictions, including British Columbia, “green” biomethane can be sold to natural gas companies or to corporations willing to pay a premium for green biomethane. This displaces non-renewable of natural gas and reduces the carbon footprint.

Paradigm Environmental | MicroSludge Wastewater Treatment Plant Management Municipal Industrial Pulp & Paper Vancouver BC Canada - modular scalable

Delivered as skid-mounted modules, a MicroSludge System occupies a small footprint and may be integrated into the existing buildings, or delivered within a self-contained engineered building. The core of MicroSludge is the cell disrupter that processes sludge at a rate of 4m3 per hour or 1,057 gallons per hour, for a total solids concentration of up to 10%.

Paradigm Environmental | MicroSludge Wastewater Treatment Plant Management Municipal Industrial Pulp & Paper Vancouver BC Canada - howitworks

WAS is subjected to enormous shear by passing through the cell disruption valve at high pressure, the combination high shear and high velocity of impact ruptures the cells of the thickened waste activated sludge, releasing the cells’ cytoplasm. The heart of the MicroSludge process is a cell disrupter, consisting of a high pressure positive displacement pump and a special cell disruption valve.

Paradigm Environmental | MicroSludge Wastewater Treatment Plant Management Municipal Industrial Pulp & Paper Vancouver BC Canada - cell lysis

The cell membranes of microbes in waste activated sludge 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 extent of digester performance improvement with MicroSludge depends on many factors.

Paradigm Environmental | MicroSludge Wastewater Treatment Plant Management Municipal Industrial Pulp & Paper Vancouver BC Canada - benefits

MicroSludge is a simple add on that can be installed and operational within 6 to 12 months, and immediately provide ongoing operating savings. MicroSludge substantially reduces the amount of waste sludge for dewatering and disposal, thus saving costs for polymer and sewage disposal. For plants that require increased digester capacity the payback is immediate and many times the cost of MicroSludge.

Paradigm Environmental | MicroSludge Wastewater Treatment Plant Management Municipal Industrial Pulp & Paper Vancouver BC Canada - environmental

Since MicroSludge is internal to the wastewater treatment plants, no special or additional environmental permits are generally required, reducing the possibility of regulatory delays. By allowing anaerobic digesters to operate more efficiently, MicroSludge is an enabling technology that converts waste to energy and reduces greenhouse gas emissions.
