Acquisition and analysis of remote sensing imagery of harmful algal blooms.
(Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)Remote sensing was long considered an obvious tool for studying the distribution of harmful algal bloom (HAB) organisms over larger spatial and shorter time scales than is possible with ship-based sampling (Tester et al. ... -
Algal biomass pretreatment in Seawater Reverse Osmosis.
(Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)Harmful algal blooms (HABs) can result in a substantial increase in the organic and solids load in the seawater feed to be treated at a desalination plant. In this chapter, the removal of this material is addressed in ... -
Algal issues in seawater desalination.
(Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)Once harmful algal blooms (HABs) reach a desalination plant, they can cause significant operational issues and potential health concerns for consumers. These issues stem from two factors – first, the algal cells produce ... -
Appendix 1. Algal species potentially harmful to desalinitation operations.
(Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)It is now well established that harmful algal blooms (HABs) represent a serious and growing threat to seawater reverse osmosis (SWRO) desalination plants worldwide. In many plants, these threats are indirectly monitored ... -
Appendix 2. Rapid screening methods for Harmful Algal Blooms toxins.
(Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)At the core of all national harmful algal bloom (HAB) programs are the monitoring programs needed to detect HAB toxins in shellfish, fish, water, or other resources sufficiently early to take management actions (Anderson ... -
Appendix 3. Methods for measuring transparent exopolymer particles and their precursors in seawater.
(Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)Transparent exopolymer particles (TEP) and their precursors produced by phyto-/bacterioplankton in fresh and marine aquatic environments are increasingly considered as a major cause of organic/particulate fouling in MF/UF ... -
Appendix 4. Preservatives and methods for algal cell enumeration.
(Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)There are multiple ways to preserve phytoplankton samples and determine the algal species composition and abundance. This Appendix provides details on some of the most common methods. Additional relevant publications are ... -
Appendix 5. Autopsy and cleaning of reverse osmosis elements affected by harmful algal bloom-contaminated seawater.
(Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)Following an algal bloom, if a change is observed in the reverse osmosis (RO) performance, an initial visual plant inspection should be carried out, including looking at and removing cartridge filters and membrane elements ... -
Bloom prevention and control.
(Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)Harmful algal blooms (HABs) are a serious and growing problem to many sectors of society, including the desalination industry. The many problems that HABs present for seawater reverse osmosis (SWRO) desalination plants ... -
Case histories for Harmful Algal Blooms in desalination.
(Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)Algae have long been an issue impacting desalination plant operation in areas prone to algal blooms or where macroalgae (seaweeds) and detritus became dislodged from the seabed. Previously and still today, operators and ... -
Creating a weekly Harmful Algal Bloom bulletin. Version 1.0. [Best Practice Description Document]
(Marine Institute, Galway, Ireland, 2018)This document describes the procedural steps in creating an information product focused on toxic and harmful phytoplankton. The product is an online Harmful Algal Bloom (HAB) bulletin for aquaculturists, who can face serious ... -
Designing an observing system for early detection of harmful algal blooms.
(Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)Harmful algal blooms (HABs) are a serious and growing threat to many desalination plants. It is therefore important to limit the impact from HABs by preventing blooms from reaching seawater reverse osmosis (SWRO) plants ... -
GlobalHAB: Evaluating, Reducing and Mitigating the Cost of Harmful Algal Blooms: A Compendium of Case Studies.
(North Pacific Marine Science Organization, Victoria, BC, Canada, 2020)Over the last two decades, several efforts have been addressed to compile what is known about the economic impacts of harmful algal blooms (HABs; e.g., Anderson et al., 2000; Hoagland and Scatasta 2006; Huppert and Trainer, ... -
Guide for designing and implementing a plan to monitor toxin-producing microalgae. 2nd Edition.
(Unesco & IAEA, Paris, France & Vienna, Austria, 2016)The first edition of this manual was first published in 2011 in Spanish. Pigmented phytoplankton is the main primary producer and constitutes the foundation of the marine food webs. Blooms, the explosive growth of ... -
Guidelines for the study of climate change effects on HABs.
(UNESCO-IOC/SCOR, Paris, France, 2021)Our planet Earth is changing. Marine and freshwater ecosystems are experiencing intense natural and anthropogenic pressures that will generate unforeseen changes in their structure and functioning. The drivers of climate ... -
HAB Publication Series Volume 1. Amnesic Shellfish Poisoning (ASP).
(UNESCO, Paris, France, 1995)In this manual a review is provided of the chemical and toxicological aspects of Amnesic Shellfish Poisoning (ASP). The document contains information on chemical structure, chemical data, where to obtain standards and ... -
Harmful agal bloom-related water quality monitoring for desalination design and operation.
(Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)Characterization of the raw seawater at plant intakes and monitoring to detect poor water quality events including harmful algal blooms (HABs) is critical throughout the lifetime of a desalination plant. HABs can result ... -
Harmful Algal Blooms (HABs) and Desalination: a Guide to Impacts, Monitoring and Management.
(Intergovernmental Oceanographic Commission of UNESCO,, Paris, France, 2017)Arid countries throughout the world are heavily reliant on seawater desalination for their supply of drinking and municipal water. The desalination industry is large and rapidly growing, approaching more than 20,000 ... -
Harmful algal blooms.
(Intergovernmental Oceanographic Commission of UNESCO, Paris, France, 2017)Harmful algal blooms are increasing in frequency and magnitude in many parts of the world, and one of the sectors of society that is being increasingly affected is the desalination industry.
