Directions for use
Bioguard Plus has been specially developed to prevent sea water (cooling) system from being fouled by lower
aquatic life forms like mussels, barnacles and algae. The dispersant in the product inhibits the colonisation of such
organisms on metal surfaces. The filming characteristics will also provide anti corrosion properties. Bioguard Plus
can be used in both static and flowing systems. Some application examples are: sea water systems, including
seawater intakes; filter boxes and piping; static ballast tanks; stability trimming tanks and oil rig sea legs.
Dosage and control
For Sea Water Cooling Systems Dose 0.6 litre of Bioguard Plus for every 100 tons of sea water flowing through the
system per hour. The system throughput is either to be determined from the rating of the pump(s) or from the system
specifications. Treatment is necessary in coastal waters and should commence three days before entering these
waters and continue for three days after leaving coastal waters. The calculated dose should be dosed over a one
hour period and repeated every 48 hours. For Static Ballast Tanks Dose 1 litre of Bioguard Plus per 10 tons of
water prior to ballasting, followed by a monthly dose of 2 litres per 100 tons. For Trim Tanks, Oil Rig Sea Legs and
similar systems Dose 25 litres of Bioguard Plus per 100 tons of water and add the same for make up water.
Dosing Method The diagram attached shows a typical dosage layout. This can be modified to suit a particular
situation. A chemical dosing pump, with or without alarm to be used. Although the product will gradually clean fouled
systems, treatment should preferably be started with a clean system. The product can be dosed neat or if necessary
diluted into fresh water to accommodate the dosing equipment. When changing over from any other product to
Bioguard Plus, flush the entire dosing system thoroughly with fresh water.
