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.

BioLargo Spotlight: Introducing the Spiral AOS

Image
Originally posted on December 14, 2018 In our previous blog posts that detailed the science behind BioLargo Water’s Advanced Oxidation System (AOS), we explained that the AOS treats water by generating reactive iodine molecules at its electrodes. The iodine molecules generated inside the AOS decontaminate and disinfect water in two fundamental ways: 1) by the oxidation of proteins inside bacteria, viruses, or protozoa and 2) by altering the structure of chemical pollutants, often breaking them down entirely. Explaining the mechanism of how the AOS works, we showcased just how effective the AOS is at reducing electrical and consumable costs while treating water. In this blog, we will elaborate upon recent radical design changes BioLargo Water has made to the AOS as part of our effort to continuously improve our technology, and we will illuminate how and why these decisions will result in a more effective and economical product for end-users.

BioLargo Spotlight: NSERC Grant Awarded to Evaluate AOS Water Chemistry

Originally posted Tuesday, October 9, 2018 If you follow BioLargo Water and its Advanced Oxidation System, you may sometimes wonder how exactly it functions – ie how does it actually treat water? You have probably seen our short descriptions of its function: that it generates highly reactive iodine molecules at its electrodes, resulting in disinfection and decontamination, but the truth is A) this is an oversimplification and B) you may not be entirely clear on what this means! To expand on this simplified explanation: in the AOS there are two modes of actions by which it treats water. One is the oxidation – the chemical action of removing electrons - of proteins inside bacteria passing through the AOS, resulting in inactivation or killing of those bacteria. The second mode of action is the breaking down of pollutants by oxidation, that is to say the structural or chemical alteration of chemical pollutants by the process of oxidation. A peak at an AOS Spiral Reactor...

BioLargo Spotlight: Pharmaceuticals in Water

Image
Originally posted on September 20, 2018 Diseases are treated and cured with man-made chemicals every day – it’s a fact of life. However, scientists and public officials have long be concerned with the question: what happens when those chemicals (pharmaceuticals) come in contact with a healthy person? As is often the case in science, the answer is: well …. It depends! When a human or animal consumes pharmaceutical products (PPs), what happens to them? These substances are excreted, disposed from the households through sewers and released into the aquatic environment. PP s  are an important group of potential  endocrine-disrupting compounds (EDCs) which have recently attracted much attention of the international scientific community. PP s  such as analgesics, antibiotics, antiseptics, hormones and antidepressants were detected in influents of wastewaters treatment plants, in surface water, in ground water and even in drinking water resources across the world. Their...
