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
- microbiologically influenced corrosion (MIC)
Year after year the environmental regulations on anti-fouling paints are becoming stricter!
- 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).
- 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
