  • Mitigation of marine biofouling on tubes of open rack vaporizers using electromagnetic fields

    This study quantitatively evaluates the antifouling action of the continuous physical treatment with electromagnetic fields (EMFs) of seawater used as heat exchanger fluid in an open rack vaporizer (ORV) pilot plant to reduce the growth of biofouling on external rib-tube surfaces. The results demonstrate that the biofilm adhered on the treated rib-tubes was reduced by 33% in thickness and by ...

  • New approaches for monitoring the marine environment: the case of antifouling paints

    Protection of ships hulls against biofouling has been a problem since man began sailing the seas. The most common protections are specially produced antifouling paints. These paints could be broadly classified in three main groups, or generations, depending on the technology applied: first generation copper-based, second generation organotin-based, and the new, third generation, organotin-free ...

  • Bio-fouling control on marine vessels with ozone

    A recent pilot study on how to control accumulation of marine organisms on heat exchangers of marine vessels show that applying ozone is both effective and sustainable. Large economic impact Marine bio-fouling, or accumulation of marine organisms on heat-exchangers for cooling systems, is a challenge in the maritime sector and has both an economic and environmental impact. Worldwide ...

  • Greening of the coasts: a review of the Perna viridis success story

    The green mussel Perna viridis has been receiving a lot of attention from workers working in the research areas of intertidal ecology, aquaculture, pollution monitoring, biofouling, zoogeography and invasion biology. P. viridis is a remarkable species in terms of its ability to reach very high biomass levels, to withstand environmental fluctuations, to concentrate a variety of organic and ...

  • AFM water treatment for biodiversity

    The discharge of List 1 bio-accumulated chemicals into the marine environment is one of the most serious forms of pollution that we inflict on our environment. The marine enviroment is responsible for the production of most of our oxygen and reduction of carbon dioxide. Tropical rainforrests and terestial plants are also extremely important in dictating our local climate, however they ...

  • Mussel colonization of a high flow artificial benthic habitat: byssogenesis holds the key

    Water flow is an important characteristic determining the settlement and growth of macroinvertebrates in the marine environment. Intake systems of coastal power stations offer a unique opportunity to study the effect of water flow on benthic organisms under field conditions. The cooling water intake system of a tropical coastal power station is used as an experimental facility to study the effect ...

  • Sea water desalination – potable water application case studies

    Challenge Facing challenges of clean water shortages in Tekoradi, Ghana with the burgeoning oil/gas sector in the area offshore, something had to be done to increase clean water supply to supply the growing needs of both the military base at Tekoradi and the surrounding community. Solution Knowing the water demands were increasing, Genesis Water Technologies ...

  • Surface Decontamination of Tin compounds (tributyltin chloride) by DeconGel 1101

    Abstract Surface decontamination efficacy of DeconGel™ 1101 on stainless steel, aluminum, and concrete surfaces contaminated with tin compound (tributyltin chloride); experimentation and associated analyses was performed with ICP-OES (Inductively Coupled Plasma-Optical Emission Spectroscopy) according to Environmental Protection Agency (EPA) SW-846 Methods: 3005A (sampling) and 6010C ...

  • Transparent Exopolymer Particles (TEP): an overlooked factor in the process of BIOFILM FORMATION in aquatic environments

    AbstractWe hypothesize that transparent exopolymer particles (TEP), present in high concentrations in most sea and freshwaters, are critical agents for biofilm initiation and development in many natural and anthropogenic aquatic environments. These gel-like particles appear in many forms, amorphous blobs, clouds, sheets, filaments or clumps ranging in size from ~2 to ~200 µm. TEP are mostly ...

  • Sea Water Desalination - Technical Article

    Sea Water Desalination is a specific process involving molecular separation via membrane technology to reduce the dissolved salt and mineral content of sea water to a level suitable for human and animal consumption, commercial/industrial and irrigation uses. This process involves three water streams namely sea water as the intake source, Product / Permeate water of potable drinking water quality ...

  • Data analytics and the materials cycle

    Data has the potential to revolutionise the materials industry, from extraction to processing to commercialisation. But it can only do so with the right mix of technology, skills and strategy. Dr Matt Jones explains. Using data is nothing new, but the rapid increase in data sources and quantity of data collected means getting the most out of it is ever more important. Properly used, data ...
