Description

Use

WS-8738 antifoulant is a liquid, hydrolytically stable, non-ionic dispersant designed for use in water systems.

WS-8738 is highly effective over a wide pH and temperature range in dispersing oil, silt, sludge, clay and dead bio-matter occurring in water systems. It will remove deposits, which reduce heat transfer and lead to underdeposit corrosion attack.

When used in conjunction with a microbiocide, WS-8738 improves the penetration of the microbiocide and contributes to better, more economical bacterial control.

Feeding

The exact dosage of WS-8738 will depend on a number of factors such as the nature and concentration of suspended solids and the degree of surface fouling already present.

• Routine maintenance control may be achieved by adding 25-200 ppm either continuously or as a shock charge.
• Severely fouled systems may be cleaned using concentrations of 50-5,000 ppm.

Your Eurochem representative will provide detailed information.

WS-8738 may be fed directly from the drum or as an aqueous dilution to any suitable point in the system. For large systems local addition to the inlet pipework of specific heat exchangers might be appropriate.
