We are continuously testing and improving our systems with the help of known partners in the shipping industry.

CIP Applications in the maritime sector include:

• Protection against bio-fouling of heat exchangers:
  • box coolers
  • tube coolers
  • plate coolers
• Treatment of sanitary water systems (tanks, pipes, calorifiers)
• Protection of marine structures against:algae
  • barnacles
  • mussels
  • microbiologically influenced corrosion (MIC)

Year after year the environmental regulations on anti-fouling paints are becoming stricter!

See for example: IMO regulations on anti-fouling

• Water treatment in pipes, tanks and filters:

• against lime scaling (calcium carbonate)

• • for reduction of bacteria growth (for example legionella pneumophilia, E. Colli,..)
  • against slime formation and algae

• Desalination plants:
  • against the formation of a biofilm in the membranes of a reverse osmosis or ultrafiltration system.

• Tests are ongoing for to help with the treatment of Ballast Water of worldwide seagoing vessels:
  • As per BWM Regulation D-2 (8 sept 2017, now postponed)
  • Limitation of indicator microbes:
    • Toxicogenic Vibrio cholerae (O1 and O139) with less than 1 colony forming unit (cfu) per 100 milliliters or less than 1 cfu per 1 gram (wet weight) zooplankton samples
    • Escherichia coli less than 250 cfu per 100 milliliters;
    • Intestinal Enterococci less than 100 cfu per 100 milliliters.

In general , the ultrasound technology is used to reduce DBPs (disinfection by-products) that are pollutants and are ozon depleting (like bromoform).

IMO WBT regulations

The USCG has similar rules in place.

• Fuel tank and filter treatment against the diesel bacteria. (avoiding slime/sludge formation and clogging)

Some negative effects of bio-fouling include:

• heat transfer loss (increasing the energy cost)
• health issues (such as pathogenic bacteria growth)
• downtime due to equipment failure (increase of operational costs)
• increase of maintenance cost (labor and material)
• decrease of equipment MTBF
• the need to use (mostly aggressive) chemicals
• increase of fuel consumption due to hull fouling
• expensive emergency drydocking’s
• …
