Q&A



“Water with its suspended matter taken on board a ship to control trim, list, draught, stability or stresses of the ship”

Ballast Water is:

IMO BW Convention

Whilst unloading cargo at the source port, ballast water is taken on board to provide trim and stability for the voyage.

Once at the destination port, cargo is loaded and ballast water is discharged to compensate.

Ballast Operations the transfer vector

Technology characteristics

UV breaks down the cell membrane killing the organism or by altering the DNA destroying the ability to reproduce

Germicidal UV-C irradiation comes in two forms:

1. Medium Pressure: uses multiple wavelengths between 200-400nm to treat the ballast water

2. Low Pressure: uses one wavelength set at 254nm to treat the ballast water

• Salinity independent

• No Active Substances

• Minimal health, safety or environmental concerns

• Effectiveness depends on organism size, turbidity, and UV transmittance

• Requires treatment during ballasting and de-ballasting

Physical Disinfection - Ultra Violet (UV)


Physical Disinfection - De-Oxygenation

Technology Characteristics:

• Injected with stripping/inert gases

• Tank head spaces are inerted

• Removing oxygen kills aerobic organisms

• Inhibits corrosion

• Efficacy requires long residence time

• Water salinity and temperature independent

• Maintaining head space as a low oxygen environment

• Water must be re-oxygenated before discharge

• Ineffective on certain types of organisms

• Cavitation is used to aid the process

Stripping gas generator

Venturi


Chemical Treatment - Electrochlorination

Technology:

• Electrical current is applied to ballast water in an electrolytic chamber, generating the Active Substance TRO.

• Full flow or side-stream arrangements

• Simple and safe method

• Inexpensive

• TRO residuals ensures Re-growth does not occur

• Flow through systems are restricted to brackish and salt water environments

• Residual TRO may require neutralising

• May need to hold ballast water if no neutralisation

• Water temperature dependant

• Produces Hydrogen as a by-product

Electrolytic cell configurations


Chemical Treatment - Ozone

Technology Characteristics:

• Injecting oxygen rich compressed air through a series of electrodes produces ozone.

• Involves an injector system or diffusers

• Acts rapidly

• Solution for all environmental ranges

• Large amounts of equipment required

• High power demand

• High capital and operational costs

• Residual ozone may require neutralising


Chemical Treatment – Inject Chemical Preparations

Technology Characteristics

• Purchased chemical preparation products are used to disinfectant ballast water

• Chemical ‘poisoning' or oxidation

• Purchased chemicals include granular sodium hypochlorite, calcium hypochlorite, PeracleanOcean, Neo-Chlor Marine

• Require neutralisation

• Perceived low cost/ no equipment

• Perceived simplicity

• Independent from water conditions to produce Active Substances

• Need for world-wide chemical supply

• Chemical storage and handling provides health and safety concerns.
