Marichem S-Fe

MARICHEM S-Fe is a concentrated aqueous liquid product formulated to control marine biological fouling of marine microorganisms such as bacteria and fungi and macro organisms such as barnacles, mussels and clams without harming higher life forms. MARICHEM S-Fe has a wide range of applications in all seawater cooling lines, seawater intakes, trimming tanks, ballast tanks etc.

Characteristics, Advantages & Applications

  • Very effective on marine biological fouling control in all seawater intake systems whilst protecting them from erosion and heavy scale accumulation.
  • Provides quick and thorough treatment.
  • Safe to use on all metals and metal alloys.
  • Non-flammable, non-corrosive and non-toxic.
  • No known effect on rubber or plastic compounds.
  • Can be combined with a range of other products.
  • No heating is required upon application and it is completely biodegradable.
  • Maintains heat transfer in the system.
  • Cost effective, easy to apply and use.

Application and Use

A. Dosing Procedure

The quantity of MARICHEM S-Fe is proportional to the capacity of seawater flow in the system, the desired treatment levels, the type and kind of the system in question, the available downtime and the degree of contamination of the system to be treated. The recommended dosage is 0.9 litres of MARICHEM S-Fe for every 100 tons of seawater flowing through the system per hour. The above mentioned dosage should be dosed during a one hour period and repeated every 48 hours. The frequency of dosage may be less depending on the degree of fouling.

B. Feeding Procedure

Once the quantity of MARICHEM S-Fe has been determined, its application must take place by use of the MARICHEM DOSING SYSTEM, into all the main seawater suction filters. This is feasible to accomplish when the DOSING SYSTEM tubing is tapped to the main seawater feeding line.

Note, that the DOSING SYSTEM must be positioned above the main seawater suction unit, over the seawater level in order to reach maximum gravity flow into the filter system while suction is in operation.

IMPORTANT NOTICE: MARICHEM S Fe should not be fed to a system while the sea water is being drawn as makeup for an evaporator or water maker. Either isolate the evaporator or shut it down while MARICHEM S Fe is being dosed and for at least 30 minutes afterward.
