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.
