7. Shipsan® for Super-chlorination

Super-chlorination using Shipsan® – Spray Method –fast and efficient

  • Radically reduces the procedure time
  • Huge saving in Disposal Costs
  • Saves valuable ship time
  • Removes Bio-film

It is ideal for use in water hygiene storage tanks and pipe work treatment applications, where it quickly eradicates Legionella, Pseudomonas and other microbes. Available in 25L, 200L, 1,000L IBC’s.

Tank clean (MGN 397); “To be opened up, emptied, ventilated and inspected and thoroughly cleaned, recoated as necessary, aired and refilled with clean freshwater chlorinated to a concentration of 0.2ppm free chlorine.  The cleaning process should include disinfection.”

  1. Clean and rinse the tank and pump out
  2. Dilute 1 litre Shipsan to 20 litres of deionised water (200 ppm free-chlorine).
  3. Spray all surfaces with Shipsan® (diluted as above) and leave for a few minutes to Superchlorinate/Disinfect.
  4. Rinse the surface and pump out
  5. When using Shipsan spray method for super-chlorinating the freshwater tanks consideration should be given to the distribution system;

Hydrophore System: Using a Hydrophore system: The hydrophore tank requires a solution of 200ppm (Measured as Free Chlorine) Shipsan is then used to sanitise the distribution system, operating all outlets to ensure the chlorination is achieved at all outlets to ensure the chlorination is achieved at all points, followed by flushing after 30 minutes.  (1 Litre Shipsanto 20 Litreas de-ionised water).

20 Litres de-ionised water).

Positive Pressure Pump System: Using a positive pressure pump system direct feed from the fresh water tank. After Super-Chlorinating the fresh water tank using Shipsan as above procedure, use a cofferdam to supply the pump inlet pipework should be filled with a solution of 200ppm (Measured as free-chlorine) Shipsan is then used to sanitise the distribution system, operating all outlets to ensure the chlorination is achieved at all points followed by flushing after 30 minutes.  (1 Litre Shipsan to 20 Litres de-ionised water).

6. Refill the tank to achieve typically 0.2ppm – 0.5 ppm (As per the levels indicated in your Water Safety Plan) using Shipsan. Test the water for free chlorine.

Dosage for Drinking Water on Board, where an infection has been identified.

Using Shipsan to dose ready for drinking instead of Sodium Hypochlorite or Calcium Hypochlorite Liquid or tablets: Refill the tank to achieve0.2ppm at the tap or 5ppm in hte  tank free chlorine using Shipsan®. Sample the waer for free chlorine.  Shipsan will give a stable free-chlorine level.

Dosage Guide: Dose for drinking Water: You will need to use 125ml of Shipsan per tonne of drinking water, this will give you 0.5ppm in the tank. For drinking water the line should be dosed immediately into the line via a dosing meter prior to distribution point after the storage tanks.
