Eagleridge's  Mission

Eagleridge's mission is to help solve the world's waste water treatment issues with simpler and more cost effective technologies.   

MicroPoP Technology

Our flagship MicroPoP technology is for the elimination of WAS (Waste Activated Sludge) - excess waste bacteria for disposal from microbial waste water treatment methods from:

  • Municipal Waste Water Treatment,

  • Pulp and Paper,

  • Oil Refining,

  • Food and Beverage Industry,

  • and Meat Processing.  


The MicroPoP key is that bacteria readily metabolize liquids, not solids.  MicroPoP breaks apart (lyses) all of the bacteria in the WAS using high pressure homogenization methods making a readily available liquified food source for the bacteria back in the process, whether aerobic or anaerobic.   The bacteria can quickly metabolize this liquefied WAS.  This simple and sustainable technology has large cost savings, reduces GHGs, and increases biogas production for RNG or CHP projects, amongst other positives.  As the WAS is eliminated, no polymers are required for WAS dewatering, nor are there any further WAS handling and disposal costs.   MicroPoP eliminates the difficult WAS waste stream while lessening environmental impacts, with up to 2X biogas from WAS digestion.  Nutrient recovery technology modules for phosphorus and nitrogen (released from inside the cells) can be added to produce useable fertilizer.

MicroPoP Brief History

MicroSludge is the cell lysing technology innovation that had been validated and de-risked over 14 years with approx $28 Million invested up to 2014.   Over that time 3 full scale demonstration projects were conducted at municipal waste water treatment plants.  Also, a $6 Million 3 year pilot plant project at a pulp and paper mill where a major innovation improvement (MicroPoP) was discovered, and USA patent applied for.   Then the predecessor company to Eagleridge entered receivership unexpectedly in 2014 just before a full scale project for Metro Vancouver was to start.   Eagleridge acquired the assets out of receivership in 2015 and continued the journey to commercialization.  The applicable MicroPoP patents were issued in the USA (2015 and 2017) and EU (2022), along with additional trade secrets.

In 2020, the phosphporus and nitrogen (ammonia) recovery technology modules were were added in a licensing arrangement with Muddy River Technologies, for applications where the 3 technologies work synergistically together.  By lysing microbes, MicroPoP releases the cytoplasm of microbes where the nutrients were concentrated and locked in, and can now be recovered as fertilizer.

Today, the MicroPoP offering is much improved with better and more widely applicable technology for the most cost effective solution for a specific facility, improved ancillary equipment systems, and enhanced with the synergistic nutrient recovery technologies for phosphorus and nitrogen (ammonia).  Together, these technologies are getting set to transform the waste water treatment industry worldwide.   We are seeking the first few full scale demonstration sites for operation of the these 3 synergistic technologies together, that will mark the launch of commercialization.

Helping the World to Zero Waste

MicroPoP eliminates waste activated sludge where it is produced.  This allows for resource recovery of phosphorus and nitrogen as useable fertilizer for value creation, thereby saving operating, processing and disposal costs and at the same time lessening the impact to the environment.   Benefits are from reducing GHGs, increasing biogas production on RNG or cogeneration CHP projects, and from other factors reducing the environmental footprint of a facility.  

Pulp and Paper

For the Pulp and Paper industry nutrients locked inside the bacteria of WAS are usually disposed of or incinerated.  MicroPoP breaks apart the bacteria in WAS, so that nutrients are released and can be re-introduced to feed the bacteria in the process, thereby reducing nutrient purchase costs, and at the same time lessening WAS handling, dewatering and disposal costs.  This also lessens GHGs in a sustainable manner.










Municipal Waste Water Treatment

MicroPoP fiits into existing  installed systems by processing the WAS that comes from secondary clarifiers.  The WAS from secondary clarifiers is generated 24/7.  MicroPoP uses cell lysis and re-circulation modifications to eliminate the WAS beneficially onsite.  Whether anaerobically with up to 2X biogas generated from WAS digestion for RNG and cogeneration CHP projects, or aerobically, WAS is eliminated.   Solids handling, dewatering and disposal costs are minimized, with corresponding GHG reductions.  Nutrient resource recovery of phosphorus and nitrogen (ammonia) is done with Muddy River's simple and cost effective add-on technology modules.  MagPi for phosphorus recovery and Misty for nitrogen (ammonia) recovery.

How MicroPop Works

cell disrupter image.png

This is what a full scale cell disrupter machine looks like.  It is about the size of a pool table and weighs 6 tonnes.  It can process the waste activated sludge produced from approx 200,000 population.  They can be lined up like lego pieces for larger populations serviced, as required.  These machines are sourced from large corporate machinery manufacturers, and have been customized and adapted for processing this particular aggressive WAS waste feed for 24/7 operations.

Other ancillary equipment is also part of the MicroPoP technology, including hydrocylcones, self cleaning screens, pumps and mixers.

The WAS feed is ideally at 8 -10% solids, so typically some WAS thickening equipment such as a centrifuge will also be required.

The cell disrupter machine pressurizes the WAS feed through positive piston pump action and a series of check valves.  The opposing valve stem located in a massive steel block at the front of the machine is adjusted until the WAS feed pressure reaches 12,000psi for a feed rate of 4 m3/hr.

This results in a small gap between the valve stem and valve seat, creating a high shear zone for the WAS feed, as it flows out radially.  The WAS feed is accelerated to approximately the speed of sound before it hits the impact ring where all of the microbes are popped, much like bugs going splat on your car windshield, before exiting past the valve stem.  The WAS feed is heated by approx 15 deg C during this cell lysing process, and the WAS feed is converted from a porridge like consistency to that like chocolate milk.
