Introduction
Caretreat 5 Seawater has been designed to effectively stop the development of micro organisms, shell
embryo, bacteria and plant life commonly found in sea water. Most fouling of ships systems is
primarily the result of microscopic organisms colonising in the pipework, attracting growth of larger
lifeforms and giving anchorage to sand and silt. Partial blockage of heat exchanger tubes reduces flow,
resulting in local overheating and subsequent scaling from hardness salts.
Directions for use
1. Sea water cooling systems
The product is injected into seachests to give a concentration of 6 ppm over a period of 1 hour every
two days that the vessel is in shallow water. This period is sufficient to remove the foulants before they
have anchored and started adult development, at which time they are extremely difficult to control. To
achieve these dosing rates, 0,6 litre of Caretreat 5 Seawater must be injected each second day for each
100 tons/h of flow into the seachest(s) (=0.006 litre/ton). Vessels which are continuously coastal must
inject Caretreat 5 Seawater at he same rates every third day.
Dosage instructions
Example : system of 250 tons/h.
