Cooling Water Treatment

We understand that cooling water systems are an integral part of process operations in many industries, with the possibility of productivity and product quality being adversely affected by scale, corrosion, fouling and microbiological contamination. 

 

These problems can be very costly when they cause the loss of heat transfer, equipment failure, and health and safety concerns.  Nalco uses  a unique engineering approach, looking at your total system from mechanical, operational and chemical angles.  We can provide best in class solutions tailored to your open recirculating, once-through, closed loop, geothermal, and process cooling systems. 

 

Corrosion and Scale Control

Nalco’s corrosion and scale inhibitors feature traced chemistries designed for use with 3D TRASAR® control systems.  With 3D TRASAR technology control, your system is monitored and feedrates are controlled for optimal, cost-effective performance. 

  

Biocontrol

We offer a complete line of oxidizing and non-oxidizing biocides, algaecides and biodispersants that are effective in many different cooling water applications, including open recirculating cooling towers, once-through cooling systems, closed loop cooling systems, air washers, cooling ponds, and pasteurizers. 

 

Our ACTIBROM®, STA.BR.EX® and ControlBrom® products can effectively reduce the amount of oxidizing biocide required to control microbiological activity in cooling water.  Our Bioreporter™ products, when used with a 3D TRASAR technology controller, detect changes in microbiological activity and adjust the biocide feedrate for tighter control and less overfeed.

 

For control of Macrofouling by zebra mussels and other mollusks, we offer effective molluscicide treatments that can be used in fresh and potable water systems.  Your sales engineer can help choose the right treatment program for your system.

 

Closed Loop Cooling Applications

Nalco also offers a full line of products for closed loop cooling applications.  Many products in our TRAC line are based on patented all-organic technology, avoiding molybdate and nitrite chemistries that have been subject to regulatory restrictions in some areas.
