Nalco 73551 25LTR (for USA and Canada only)

Approved by the U.K. Department of the Environment as a marine antifoulant in the inlet of evaporators producing potable water

This bio-dispersant has been specially developed to prevent sea water (cooling) system from getting fouled by lower aquatic life forms like mussels, barnacles and algae. The dispersant in the product prevents bacteria to colonise the metal surface, making it unsuitable for settling of bacteria and therefore less favourable for larger fouling organisms. The filming characteristics will also provide anti corrosion properties. Bioguard 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 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 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 per 100 tons of water and add the same for make up water.

Dosing Method The diagram above 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, flush the entire dosing system thoroughly with fresh water.
