  • The Valorisation of Sargassum from Beach Inundations
    Journal of Marine Science and Engineering Review Golden Tides: Problem or Golden Opportunity? The Valorisation of Sargassum from Beach Inundations John J. Milledge * and Patricia J. Harvey Algae Biotechnology Research Group, School of Science, University of Greenwich, Central Avenue, Chatham Maritime, Kent ME4 4TB, UK; [email protected] * Correspondence: [email protected]; Tel.: +44-0208-331-8871 Academic Editor: Magnus Wahlberg Received: 12 August 2016; Accepted: 7 September 2016; Published: 13 September 2016 Abstract: In recent years there have been massive inundations of pelagic Sargassum, known as golden tides, on the beaches of the Caribbean, Gulf of Mexico, and West Africa, causing considerable damage to the local economy and environment. Commercial exploration of this biomass for food, fuel, and pharmaceutical products could fund clean-up and offset the economic impact of these golden tides. This paper reviews the potential uses and obstacles for exploitation of pelagic Sargassum. Although Sargassum has considerable potential as a source of biochemicals, feed, food, fertiliser, and fuel, variable and undefined composition together with the possible presence of marine pollutants may make golden tides unsuitable for food, nutraceuticals, and pharmaceuticals and limit their use in feed and fertilisers. Discontinuous and unreliable supply of Sargassum also presents considerable challenges. Low-cost methods of preservation such as solar drying and ensiling may address the problem of discontinuity. The use of processes that can handle a variety of biological and waste feedstocks in addition to Sargassum is a solution to unreliable supply, and anaerobic digestion for the production of biogas is one such process.

  • Evaluation of Sorption Materials for the Removal of Organic Micropollutants in Domestic Wastewater and Their Potential Infiltration in Groundwater
    Evaluation of sorption materials for the removal of organic micropollutants in domestic wastewater and their potential infiltration in groundwater Master thesis 45hp Ande Rostvall Dept. Chemistry-BMC, Analytical Chemistry Uppsala University (UU) and Dept. Aquatic Science and Assessment Swedish University of Agricultural Sciences (SLU) 2017 VT Supervisor: Pablo Gago Ferrero Examiner: Christer Elvingson Subject Specialist: Per Sjöberg Abstract The presence of micropollutants (MPs) in the water systems is a growing concern, as these substances may trigger unwanted ecological effects and can be toxic to humans and wildlife. The main sources of MP contamination are the discharges from inadequately treated wastewater. In sparsely populated areas (including large areas of Sweden), where the establishment of conventional wastewater treatment plants (WWTPs) for the sanitation of wastewater is not feasible, the use of more cost-effective small-scale on-site sewage treatment facilities (OSSFs) is widespread. OSSFs are important sources of MPs and there is a growing concern since these facilities can potentially contaminate groundwater. The present project aims at evaluating the performance of different adsorbents potentially useful for the removal of organic MPs in OSSFs: granulated activated carbon (GAC), Xylit, lignite, sand and GAC followed by Polonite (GAC+P). A set of 83 MPs from different categories including pharmaceuticals, per- and polyfluoroalkyl substances (PFASs), stimulants and parabens, among others, were used to assess the performance of the selected adsorbents. GAC+P and GAC showed the best removal efficiencies (close to 100% for most of the compounds), showing no statistically significant difference between them. This fact suggests that the role played by Polonite in the removal was not significant.

  • Reduction of Organic Micro-Pollutants in Sewage Water - a Structure-Adsorption Relationship Study and Detailed Characterization of Natural Adsorbent
    Reduction of organic micro-pollutants in sewage water - a structure-adsorption relationship study and detailed characterization of natural adsorbent Shiromini Gamage Student: Shiromini Gamage Master Thesis: 30 ECTS Report passed: Supervisor: Patrik Andersson Examiner: Erik Björn Abstract Sewage is water that contains waste in liquid form and as suspension. Micro- pollutants (MPs) in waste water are a major environmental problem facing humanity nowadays. MPs raise concern due to potential toxicological effects on human health and ecosystems at low concentrations. Environmental studies have found that leakage from landfills, waste water treatment plants (WWTPs) and onsite sewage facilities (OSSFs) are major sources for MPs to the aquatic environment. Waste water treatment for removal of MPs is a major challenge because it entails integrated processes in technical as well as economical terms. In this study, 18 different substances were studied including pharmaceuticals, pesticides, surfactants, plasticizers and UV stabilizers. These compounds were selected considering their availability and maximum concentrations in effluent water system, bio-concentration factor, half-life, removal efficiency and the ratio of predicted environmental concentration and predicted no effect concentration (PEC/PNEC). Ozonation, reverse osmosis, electrolysis, ion exchange and adsorption techniques are identified as efficient techniques to remove MPs. Among all those techniques, adsorption has demonstrated efficiency and economic feasibility as waste water treatment. In this study, ten different low cost organic and inorganic adsorbent materials were characterized using various spectroscopic methods including X-ray photoelectron spectroscopy (XPS), diffuse reflectance Fourier transform infrared spectroscopy (DF-FTIRS), scanning electron microscopy together with energy dispersive X-ray spectroscopy (SEM and EDS) and Brunauer-Emmett-Teller (BET) surface area analysis.

Mikroföroreningar (MP) har också hittats i både ytvatten och grundvatten, vilket indikerar otillräckligt avlägsnande av MP i dessa anläggningar. Det övergripande syftet med denna avhandling var att undersöka olika typer av organiska och oorganiska filtermaterial (sorbent) för att identifiera en lämplig typ eller kombination av typer med hög kapacitet att ta bort en mängd MP från avloppsvatten i småskaliga anläggningar. Samtidigt har konventionella parametrar och ämnen (t ex N, P) i avloppsvattnet studerats för att undersöka om studerade sorbent även samtidigt kan avskilja dessa. Två kolonnförsök i laboratorieskala, följt av ett fältförsök, utfördes för att studera avskiljningen av en uppsättning organiska MPs genom filtrering med organiska och oorganiska sorbent.
