  • Comparison of Biofouling Control in a Membrane Bioreactor Via Two Coarse Bubble Aeration Cycles

    In the membrane bioreactor (MBR) process, coarse bubble aeration is used to scour the surface of the membranes to help control biofouling. Energy required for coarse bubble aeration represents a significant fraction of the total power demand for these systems. To reduce this demand, MBR systems manufactured by Zenon Environmental Inc. operate with cyclic aeration, using a cycle of 10 seconds on ...

  • Does your cooling tower have a biofouling problem?

    What’s growing in your tower? It’s important to be able to identify microbial biofouling in the industrial cooling systems that you treat. We know that biofouling is a bad thing … reducing the heat transfer performance of a cooling system, as well as causing microbially induced corrosion, harboring pathogens, and accumulating scale deposits. All these problems can ...

  • Prevent biofouling and reduce fuel costs in sea chests, hulls and cooling basins

    Biofouling growth increases the drag on a hull which results in a ship that uses up to 40% more fuel and correspondingly produces 40% more CO2 emissions. The marine industry globally spends billions of dollars in addressing fouling, using a variety of protection methods such as coatings. LG Sonic, a Dutch algae and biofouling control solutions provider, has introduced an Industrial Line which ...

  • Controlling Scale Deposition and Industrial Fouling

    It costs US industry billions of dollars a year to control and remove the limescale that builds up in industrial equipment such a heat exchangers, evaporative coolers, boilers, chillers and other water fed equipment. Oil wells, for example, face significant scaling problems from the highly mineralized water that are extracted with the oil. Limescale not only increases downtime, maintenance ...

  • Biofilm control strategies in industrial processing waters

    Bacterial biofilms cause a number of serious problems for industrial fluid processing operations. Mechanical blockages, impedance of heat transfer processes and microbially induced corrosion result in billions of dollars of losses each year. In engineered systems, such as cooling water systems, food processing, and other industrial applications possible risk to public health and product spoilage ...

  • Learning to Live With Biofilm: The Challenge of an Effective Biofilm Control Program

    The organism always wins. This is the challenge of biofilm control. Microbial biofouling and its root cause, biofilm, cannot be totally prevented, at least for a practical length of time in industrial settings. We have many approaches to keep it at bay but it will always be with us. In industrial water treatment, our goal is to keep biofouling  ...

  • Ultrasonic algae control solutions to treat smaller water areas

    Algae has an import function in nature, it provides food and energy for animal life, and much of the earth’s oxygen. However, an excess of algae can be hazardous to both humans and animals. Research has demonstrated that ultrasound can be an effective method of controlling algal blooms. Ultrasonic algae control solutions: the differences There are various ...

  • Controlling scale deposits in the pulp & paper industry

    The pulp and paper industry is one of the heaviest users of water within the North American industrial economy, requiring on average 54 cubic meters of water per metric ton of finished product.  As water is used in nearly every part of the manufacturing process, accumulation of scale is a phenomenon that can occur in all pulp and paper making processes. This occurs even with the purest water ...

  • Algae control in drinking water treatment - case study

    For the Ministry of Agriculture in Cyprus, LG Sound b.v installed 33 LG Sonic, ultrasonic devices in the Limassol water treatment plant, to prevent bad odour and taste to the water caused by geosmins in the water. The earthy taste problem persisted during summer of 2010 and various physical, chemical and biological tests were done in order to check the process efficiency, which showed problems ...

  • 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 ...

  • Biofilm control in water by advanced oxidation process (AOP) pre-treatment: effect of natural organic matter (NOM)

    The main goal of this study was to examine the influence of natural organic matter (NOM) on the efficiency of H2O2/UV advanced oxidation process (AOP) as a preventive treatment for biofilm control. Pseudomonas aeruginosa PAO1 biofilm-forming bacteria were suspended in water and exposed to various AOP conditions with different NOM concentrations, and compared to natural waters. H2O2/UV prevented ...

  • Removing biofilm from membranes – a practical approach

    Abstract Within the lifetime of most reverse osmosis (RO) systems some fouling will adversely affect membrane performance.One of the major foulants identified on lead membranes during a decade of membrane autopsy at the Genesys Membrane laboratory is biological fouling (biofouling). All raw water sources contain microorganisms such as algae, bacteria and fungi. They also contain ...

  • 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 ...

  • Recovery of methane from anaerobic process effluent using poly-di-methyl-siloxane membrane contactors

    This paper demonstrates the potential for recovering dissolved methane from low temperature anaerobic processes treating domestic wastewater. In the absence of methane recovery, ca. 45% of the produced methane is released as a fugitive emission which results in a net carbon footprint of −0.47 kg CO2e m−3. A poly-di-methyl-siloxane (PDMS) membrane contactor was applied to support sweep gas ...
