BioLargo's 3D Printer Hard at Work

Check out BioLargo Water's 3D printer hard at work! This bad boy is making us a bespoke mixing tool for use the mixing tank we use for water to be treated by the AOS in the lab. Our in-house 3D printing expert Carter can fabricate objects you wouldn't believe with this thing!

BioLargo Spotlight: AOS and SAGD Water Grant

Re-posted from Hello again from Edmonton, this is BioLargo Water Senior Research Scientist Dr. Parastoo Pourrezaei. Today I want to bring you some information about what I believe is one of our most important development areas for the Advanced Oxidation System (AOS). As you may know, the AOS is a powerful water treatment technology with great potential to bring cost-efficient and reliable water treatment to diverse market applications, and this includes oil and gas water treatment and reuse.  Within oil and gas water treatment, there exists a very important application: the treatment and reuse of water produced in steam assisted gravity drainage (SAGD) operations, a process commonly used to extract bitumen from oil sands. In this process, steam is injected underground to enable the extraction of bitumen from the formation, and as a consequence of this, a significant amount of contaminated water is produced, which we refer to as SAGD-produced water. Nowadays, ther…

BioLargo Spotlight: Advanced Oxidation System (AOS) Versus Waterborne Viruses

Re-posted from Hello, my name is Dr. Laura Patterson-Fortin, lead for BioLargo Water’s disinfection R&D team in Edmonton. My team has previously reported many exciting results using the AOS for water disinfection. In today’s blot post, I hope to inform our shareholders and followers of some really positive recent results we’ve achieved in virus disinfection, and to share a little bit on how and why we choose to use viral surrogates for our studies, namely Bacteriophages T4 and MS2.  First, the results! You may have read in previous disclosures that our AOS consistently eliminates about 4 logs (or 99.99%) of Bacteriophage MS2 from water, which is more than a sufficient level of virus disinfection for most target water treatment applications. We’re proud to say that because of physical improvements to our AOS, we’ve increased our MS2 disinfection performance rate to 6 logs (or 99.9999%), which is effectively a 100x increase in performance. This is terrific ne…

Video Showing Coagulation and Flocculation!

Today we bring you a neat little demonstration. Senior BioLargo Research Scientist Dr. Parastoo Pourrezaei has been refining a process to reduce the amount of Total Suspended Solids (TSS) in poultry industry water before it gets treated by the AOS - this ensures the AOS performs optimally in its important job of eliminating bacteria and organic compounds from the water, and ensures the AOS requires as little maintenance as possible.

This demonstration in the video below shows the coagulation, flocculation, and sedimentation of TSS particles in test jars. In this way, Dr. Pourrezaei can select the ideal coagulation/flocculation regimen for optimal pre-treatment prior to AOS water treatment.

In this case, she is testing a variety of different metallic coagulants! The sedimentation took place over 18 minutes following the coagulation/flocculation step (the video is sped up).

Processes like this are nothing new to the world of water treatment science, but it's crucial that they are o…

250 Gallons of Pink Water

Want to see what 250 gallons of poultry chill tank water looks like? Just look at the picture below. Your eyes don't deceive you, the water is indeed pink from having poultry bathed in it for hours on end. Poultry chill tanks are commonly used to bring poultry carcasses down to a temperature of 4C for safe processing, and is very important for the prevention of food contamination. If you're interested, you can read more here.

We're about to treat this nasty water with our AOS treatment train to allow it to meet regulatory discharge and water re-use standards. By doing this, we can allow poultry processors to save money on discharge fines, and even reuse the water, saving on fresh water intake.

BioLargo Water Visits CSU Fresno

BioLargo Water's President Dr. Richard Smith and company research scientist Jenny Boutros were invited to present on our disruptive AOS technology at the beautiful California State University Fresno on Wednesday.

By the look on their faces it seems these Canadians aren't used to this much sun!

BioLargo Lab Techs in Action

Meet some of BioLargo Water's intrepid lab technicians!

Cassie (top) can be seen preparing bacterial solutions for testing, and Moustafa (bottom) is using our UV spectrometer to measure the removal of Total Suspended Solids (TSS) from water by the AOS!

COD Test!

This is a test that measures the Chemical Oxygen Demand (COD) in water! COD is a measure of how much oxygen needs to be consumed in order to chemically react with the organic matter in a solution. In other words, COD measures how much organic matter is in a solution by asking "how much oxidation would need to happen to eliminate all these organic compounds?".

It also happens to be a very colorful test.

Our new sand filter pre-treatment device!

Is this what you thought a sand filter would look like? This is our new state-of-the-art sand filter device that we use to pre-treat water that goes into the AOS Prototype, ensuring the water doesn't contain excess levels of solids and other troublesome materials before it enters the AOS.
