Seawater dispersant is a highly effective dispersant for keeping seawater cooling system free from marine fouling. Keeping seawater cooling systems free from microbiological bacteria and fungi or macro biological.
Seawater dispersant SWD is a highly effective dispersant for keeping seawater cooling system free from marine fouling. Keeping seawater cooling systems free from microbiological (bacteria and fungi) or macrobiological (mussels, plants, etc.) growth is essential for maintaining the cooling capacity of today’s high efficiency systems. When used on a regular basis, DREWSPERSE SWD seawater dispersant prevents fouling by dispersing sea growth and preventing it from adhering to marine heat transfer equipment. DREWSPERSE SWD dispersant does not contain any phenolics, chlorinated solvents or other harsh chemicals.
It is recommended that the seawater cooling system be cleaned prior to beginning a prevention program featuring dispersant. The reason for cleaning is that if the cooling system is already fouled, the product will disperse new growth present but not existing growths.Therefore, to achieve the desired heat transfer condition,we recommend that all existing growth be removed.
Seawater dispersant may be dosed via a gravity head tank and flow-meter, an eductor dosing unit, or a suitable pump and tank system to a sea chest at the recommended concentration rate of 6 ppm for a period of one hour. To achieve 6 ppm, dose 0.6 liters of Seawater dispersant per 100 tons of water flow. Dosage should be for one hour. The best point for injection of the dilute solution of the product is immediately after the external sea chest COOLING WATER TREATMENT strainer. This provides total dispersion and mixing with the seawater. The mixed solution thus will contact all parts of the seawater cooling system

| General advice | These recommendations provide general guidance for handling this product. Personal protective equipment should be selected for individual applications and should consider factors which affect exposure potential, such as handling practices, chemical concentrations and ventilation. It is ultimately the responsibility of the employer to follow regulatory guidelines established by local authorities. Keep away from food, drink and animal feedingstuffs. When using do not eat, drink or smoke. Ensure that eyewash stations and safety showers are close to the workstation location. |
| Exposure controls | Provide sufficient mechanical (general and/or local exhaust) ventilation to maintain exposure below level of overexposure (from known, suspected or apparent adverse effects). |
| Eye protection | Safety glasses with side-shields |
| Skin and body protection | Wear as appropriate: Safety shoes Wear resistant gloves such as: Nitrile rubber |
| Respiratory protection | When workers are facing concentrations above the exposure limit they must use appropriate certified respirators |
