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

Keywords: Waste Activated Sludge

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.

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 - wastetoenergy

To encourage diversification of electrical power from the grid towards green energy, many governments offer economic incentives to produce electricity from renewable sources. At many industrial and municipal wastewater treatment plants, waste activated sludge is produced in large quantities and must be disposed of at significant cost.

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.
