BioLargo Spotlight: Pharmaceuticals in Water


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. PPs are an important group of potential endocrine-disrupting compounds (EDCs) which have recently attracted much attention of the international scientific community. PPs 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 occurrence and persistence in the aquatic ecosystems can lead to an adverse impact on human life and aquatic systems. Research has shown that PPs may mimic or alter endocrine system pathways, potentially leading to forms of gene alteration (Boberg et al., 2010; Verlicchi et al., 2012). Once in the environment, pharmaceutically active PPs can produce a wide variety of subtle effects on aquatic and terrestrial organisms. Thus, it is crucial to develop efficient and cost-effective treatment technologies for removal of such compounds from water.

Pharmaceutical products (PPs) are a large and diverse group of compounds designed to prevent, cure and treat disease and to improve health. The prevalence of their usage is increasing constantly due to numerous factors such as the discovery of new diseases, the expanding population, the inverting age structure in the general population, and expiration of patents and the consequent availability of less expensive generics. The annual production volume of drugs has been estimated to be several hundreds of tons. (Martinez et al., 2011; Halling Sorensen et al., 2011).

Examples of pathways for pharmaceuticals to enter the environment





Trace concentrations of human and veterinary pharmaceutical compounds and metabolites have been detected in surface water, groundwater, and drinking water even after going through water treatment including conventional physical and biological treatment processes. Wastewater treatment plants are not yet efficient in removing these micropollutants (PPs) from wastewaters so they are released to the environment. Several pharmaceutical products cannot be oxidized even during conventional biological treatments. Other treatment technologies such as membrane processes are being increasingly implemented in water treatment because these technologies combine process stability with an excellent effluent quality. However, factors such as the cost of treatment, the tendency for membranes to foul, and for pollutants to accumulate in the reject stream are major issues for this technology.

Currently, efforts are directed toward environmentally friendly, less expensive, relatively simple and efficient technologies that can oxidize persistent organic pollutants. BioLargo’s Advanced Oxidation System (AOS) has been successfully demonstrated for oxidation of emergent organic contaminants such as PPs. The preliminary investigation conducted by the research team of Centre Des Technologies De L’Eau (CTE) using the AOS was very promising. The AOS has proved to be an efficient treatment tool for municipal wastewater (MWW) loaded with pharmaceutical pollutants such as Carbamazepine (CBZ), Ibuprofen (Ibu) and Amoxicillin (Amox). The contribution of the AOS to remove PPs from MWW exceeded 95%. Funded by the Canadian ARD NSERC grant, BioLargo and CTE researchers are optimizing the AOS technology for an efficient treatment of MWW loaded with PPs. This project aims to establish the economic and environmental interest of the AOS process for the treatment of persistent organic compounds such as PPs.

BioLargo Spotlight Blog Post: BioLargo Water’s Science and Engineering Team


Some time ago, we introduced readers of our blog to Kenneth Code, the inventor of BioLargo’s Advanced Oxidation System (AOS) technology as well as BioLargo’s other iodine-based technologies, and gave readers some insight into his vision and his methods. Today we want to introduce the other senior science and engineering team members who are hard at work to drive the development of the AOS towards commercialization. The AOS is a highly innovative and powerful novel technology for cost-efficient water treatment. Understandably, it’s also incredibly complex. It takes a very talented, bold, and tireless group of people to push an technology such as the AOS from the invention phase all the way to piloting and commercialization, and we’re proud to say our crew can easily be described as such.

There are many different aspects to the AOS development project that require diverse skill sets. The AOS is a powerful water disinfection device, and therefore experts in microbiology and disinfection are needed. It also has capabilities in breaking down hard-to-treat organic contaminants, and therefore chemical engineering specialists are needed. It is also a complex electrochemical device, and therefore expertise in cutting-edge electrochemistry is needed. And obviously, the AOS is a dynamic feat of physical design and engineering, and therefore design engineering and fluid dynamics expertise is required. All these facets of the AOS necessitate a very diverse team – and that’s what we have.

BioLargo a Title Sponsor at Sustain OC’s Water Solutions 3 ConferenceBioLargo a Title Sponsor at Sustain OC’s Water Solutions 3 Conference


Today, BioLargo had the pleasure of sponsoring Sustain OC’s Water Solutions 3 Conference at University of California at Irvine (UCI). This was the third annual Water Solutions conference hosted by Sustain OC, Orange County’s innovative sustainability accelerator, and it focused on new strategies and innovative technologies for managing, treating, and delivering water in the Orange County area. The conference’s other Title Sponsor was the Metropolitan Water District (MWD) of Southern California, a leader in innovation in the water industry. 

As a reminder the MWD’s Innovative Conservation Program (ICP) has sponsored important studies on BioLargo’s AOS water treatment device in the last year, and will soon be sponsoring another!

BioLargo’s Odor-No-More also exhibited at the conference, giving demonstrations of the company’s disruptive industrial odor and VOC control product, CupriDyne® Clean. CupriDyne Clean is currently enjoying early adoption in the wastewater treatment industry, where its ability to eliminate odor-causing chemicals rather than masking them, its eco-friendly formula, and its dramatically lower prices appeal to municipalities. 

A big thanks from BioLargo goes out to the Sustain OC crew who put on an amazing conference. You can learn more about Sustain OC at their website and twitter account!

BioLargo Spotlight: Oil and Gas Industry in Alberta and the AOS



Albertan Oil Sands deposits in Canada cover a surface area of over 140 000 km2 and represent major value for Canada as quantified in Figure 1. These deposits are a mixture of bitumen, clay, moisture, and sand. Bitumen extraction requires on average of 3.1 barrels of freshwater for every barrel of oil produced. Water is drawn from the nearby Athabasca River and the processed water is then stored in large tailings ponds shown in Figure 2. The environmental risks and the high costs associated with wastewater storage and onsite maintenance onsite represent major challenges to industry, regulators, and stakeholders. The oil sands process waters are different from other conventional Oil & Gas process water. It is still extremely toxic, however, not all OSPWs are similar in complexity and toxicity. 

Different organic compounds contribute to toxicity of OSPW. Naphthenic Acids (NAs)and polyaromatic hydrocarbons have been identified as toxic components in OSPW. Toxic effects of NAs are due to composition more than concentration. These compounds can damage nearby aquatic ecosystems upon their introduction, and it is therefore imperative to identify suitable protocols for the treatment of OSPW.

Figure 1. Value of energy to Canada up to 2009    













The AOS has the potential to introduce cost-efficient treatment of oil sands process-affected water as compared to conventional methods. It has a proven efficacy in eliminating naphthenic acids and polyaromatic hydrocarbons from synthetic water at significantly low energy consumption than competitors. BioLargo Water recently submitted a full project proposal for the Clean Growth Program in collaboration with two of the biggest oil sands companies in Alberta. This project will validate the AOS’ ability to remove these contaminants from real industrial OSPW in laboratory and field-simulated settings and will establish proof-of-claim evidence of the AOS’ ability to remediate OSPW. This will present a huge market opportunity the AOS as containment of OSPW in tailings ponds in Alberta is anticipated to reach more than 1 billion m3 of water by 2025. By 2040, these tailings are expected to occupy 310 Km3, an area nearly the size of Vancouver. Given the large volume of water in these ponds and possible leaching of toxicants to nearby environment, the importance of OSPW treatment is extremely high.
