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.

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.
