1. Operando Studies Of Iodine Species In An Advanced Oxidative Water Treatment Reactor 12/14/2021

   We present an electrochemical advanced oxidation process (eAOP) reactor employing expanded graphite, potassium iodide (KI), and electrical current, which demonstrates an exceptionally high rate of inactivation of E. coli (106 or 6log10 reduction in viable cells) at low current density (0.12mA/cm2), with low contact time (5 minutes) and low concentration of KI (10 ppm; 0.06mM)). Operando X-ray fluorescence mapping is used to show the distribution of iodine species in the reactor, and operando X-ray absorption spectroscopy in the anodic chamber reveals iodine species with higher effective oxidation state than IO4 – . Operando electrochemical measurements confirm the conditions in the anodic chambers are favourable for the creation of highly oxidized iodine products. The killing efficiency of this new eAOP reactor far exceeds that expected from either traditional iodine-based electrochemical water treatment or advanced oxidation systems alone, a phenomenon that may be associated with the production of highly oxidized iodine species reported here.

2. How To Improve Water Conservation In Food And Beverage Processing 12/2/2021

   The production of food and beverage products in the U.S. accounts for around one-third of the total freshwater use of the country. While it is unimaginable to consume so much water just for yourself, industrial and agricultural applications are on a scale of their own. At the rate we are going, water demand is not going to slow down anytime soon. Water supply, on the other hand, is going in the other direction.

   This is the third article in a series of articles and case studies examining the adoption of innovative solutions in water treatment and the market drivers of change influencing how companies in various industries manage their wastewater.

4. Wastewater Treatment Professionals In The Poultry Industry Are Using SDOX® Technology To Overcome Operational Challenges 11/30/2021

   This is the second in a series of articles and case studies examining the emergence of sustainably-driven innovation within the wastewater treatment functions of the food and beverage industry as sustainability and production issues intersect and influence how companies manage their wastewater.

5. AOS Water Treatment Technology Quebec Pilot 11/29/2021

   BioLargo’s Advanced Oxidation System (AOS) water treatment platform was deployed on-site at a municipal wastewater treatment plant in the town of Vaudreuil-Dorion, near Montreal, Quebec. The AOS is BioLargo’s tertiary wastewater treatment technology that empowers operators with greater energy efficiency, tolerance to fluctuations in input water quality, and – best of all – elimination of hard-to-treat micropollutants like pharmaceuticals, without sacrificing disinfection efficacy. The AOS is designed to safeguard wastewater treatment in the face of emerging water contaminants while providing triple-bottom-line benefits thanks to its extreme energy efficiency.

6. How To Mix CMC (Carboxymethyl Cellulose) 11/19/2021

   Like many other hydrocolloids the dispersion of CMC using conventional agitators can be difficult. In this video see how Silverson High Shear mixers provide one of the quickest and easiest means of dispersing and hydrating CMC, ensuring a consistent, agglomerate-free mixture and help improve processing times and costs.

7. A Guide To Preparation Of Carboxymethyl Cellulose (CMC) Solutions 11/18/2021

   Carboxymethyl cellulose (CMC), also known as cellulose or cellulose gum, is water-soluble and used to bind free water. Since it has a tendency to form lumps or fish-eyes when in contact with water dispersion of CMC using conventional agitators can give rise to several problems. Read how a high shear mixer can overcome those challenges.

8. Opportunity Meets Preparation 11/10/2021

   The Water Online editorial staff sat down with Dennis Calvert, CEO of BioLargo, at WEFTEC 2021 to discuss BioLargo’s PFAS solutions, the state of the water industry, and their AOS water treatment technology.

9. Contaminant Detection In Yogurt 11/2/2021

   Rapid progress being made and both yogurt production plants means manufacturers must modernized and upgraded to meet the demands of the consumer in the Greek and international markets. Read how one yogurt manufacturer ensures product safety and brand protection by detecting contaminants of various size and materials.

10. Compressed Air For A Cleaner Future 11/1/2021

    For almost 200 years, the wastewater management sector in Portugal has had to face ever-increasing challenges, brought about in large part by the rapid population growth since the beginning of the industrialization process of the mid-19th century. This growth was compounded by rapid development of the textile industry in the north of the country, where many of the manufacturers are located in the region around the Ave River. See how Kaeser's turbo blowers helped support sewage plants in achieving their environmental goals.
