BRAKING NEWS FOR THE SHIPPING INDUSTRY

Biofil are formed by the unwanted settlement of single and multicellular organisms on liquid carrying surfaces. Initially, dissolved organic molecules are adsorbed onto any submerged material, held namely by the van der Waals forces. Then, bacterial and algal cells adhere to the surface, mediated by secretion of glue – like substance of extracellular polymers or EPS, which contain polysaccharides, proteins and nucleic acids. As the biofilm matures, it starts to disperse and spread over a larger area. It also hardens, which increases its mechanical resistance. The formed community secretes a number of chemical cues that attract bigger, often sessile organisms, like mussels and barnacles on various locations such as hulls, seawater cooling systems, propellers, tanks and freshwater generators. In industrial plants, biofilm favors the deposition of organic and inorganic residues, which leads to accelerated corrosion. In industrial and shipping cooling systems, biofilm hosts bacteria species such as
Legionella or Pseudomonas.

Causes of Engine Overheating

Common causes of engine overheating on large ships include:

• Insufficient Coolant Levels: Leaks or malfunctioning pumps can cause a drop in coolant levels, leading to inadequate heat dissipation.
• Clogged Coolers: Saltwater and debris can block the cooling system, reducing the effectiveness of heat exchange.
• Faulty Thermostats or Sensors: If the temperature control systems malfunction, they may fail to regulate engine temperature properly.
• Inadequate Ventilation: Blockages in air intakes or malfunctioning fans can prevent the engine from cooling properly.
• Overload or Poor Maintenance: Running the engine under heavy load or failing to maintain it properly can lead to overheating.

THE PROBLEM NOBODY TALKS ABOUT

Anti-corrosion coatings don’t last long and are often washed or scraped off when divers are cleaning.
Biofilm then takes over and forms colonies inside the pipes. This “carpet” of unwanted biological organisms,
such as seaweed, algae, and bacteria, restricts the flow and, in turn, lowers the thermal performance of the cooler–
which affects all the equipment connected to the box coolers.

Ultrasound controls biofilm and bacteria. Without biofilm and bacteria, no growth occurs.
Without sufficient cooling, a common consequence is that the ship must reduce its speed, leading to major financial consequences

Ultrasound is the premium system for clean sea chest, box coolers, strainers,
hull and freshwater tanks and replace expensive and dangerous chemicals.

ULTRASONIC BALLAST WATER DISINFECTION

The ultrasonic treatment system has demonstrated to be effective in the killing of bacteria, plankton, and larger organisms.
The ultrasonic disinfection of ballast water is a mechanical/ physical treatment, which avoids the dosing of any strong
and expensive active chemicals into the ballast water. This ensures an ideal environmental acceptability combined with high
biological effectiveness regarding the destruction and inactivation of plant and animal organisms and microorganisms in the ballast water tank.
