Nalco 7308 is a liquid surfactant based dispersant program designed to provide oil, grease, and microbiological fouling control in once-through and recirculating cooling water systems. It also helps in general particulate dispersancy, including particulate iron. It is used for situations where fouling tends to be heavy and can also be used for cleaning severe hydrocarbon and/or microbio fouling out of a system.

– Function: Prevents scaling and corrosion in cooling and retort water systems.

ULTRION 8187 is a high actives, low molecular weight liquid cationic coagulant designed for potable water treatment applications.
ULTRION 8187 can eliminate the need for alum and other inorganic chemical treatments; reduce or eliminate the need for pH adjustment form a compact, easily dewatered sludge; and function over a pH range of 5-10.
ULTRION 8187 is resistant to chlorine and can be used in pre-chlorinated water without a reduction in activity.

Principal Uses: Primary and secondary clarification, municipal and industrial raw water clarification, lime softening, heavy metal removal, and oily emulsions.

NALCO 4221 is an organic corrosion inhibitor used for scavenging oxygen and passivating metal surfaces.
NALCO 4221 can be used as a direct replacement for hydrazine in boilers without the safety hazards and handling precautions associated with hydrazine.
NALCO 4221 reduces corrosion rates because it passivates feedwater and boiler internal systems.Lower corrosion rates from passivation translate directly into lower maintenance costs and reduced boiler downtime.
NALCO 4221 can be used in boiler systems operating at pressures up to 2500 psig (172 barg).
NALCO 4221 does not contribute dissolved solids, so it can be used ahead of spray attemperator water take-offs. It can also be used for wet lay-up of boilers and nondrainable superheaters.

– Function: Scale and corrosion inhibitor for water treatment.
– Application: Used in industrial boilers and cooling systems.

Tri-ACT 1800 is a corrosion inhibitor that contains a blend of low, medium and high volatility amines designed for use in steam and condensate systems.
Tri-ACT 1800 provides effective neutralization of acidic gases, such as CO2, throughout a condensate system. It may be used at temperatures up to 593°C (1100°F).
Tri-ACT 1800 effectively reduces condensate system maintenance costs and minimizes the potential of boiler tube failures caused by metallic corrosion products in the returned condensate.

– Function: Corrosion inhibitor for steam condensate systems.
– Application: Used in industrial boiler systems to prevent corrosion in steam lines and condensate return systems.

The Nalco Cooling Water Treatment Program consists of the following products which given in below

Corrosion & Scale Inhibitor: 3DT404:

Nalco 3DT404 is an innovative no phosphorous-containing corrosive scale inhibitor. It is a specially formulated product using proprietary blend of polymers to control iron,manganese, calcium carbonate , calicum Phosphate, calcium suplhate, Zinc and suspended solid deposition in high stress cooling water system.

Nalco 3DT404 may be fed as one part of a multiproduct 3D TRASAR program (including cathodic and anodic corrosive inhibitors) for cooling water systems.
