Dust Control

At Nalco Water, we understand that dust can create serious health and environmental issues for your mining operation. Without the proper dust control solution, challenges with dust can strain your bottom-line results. Nalco Water offers a comprehensive line of dust suppression additives including foam dust control, surface tension reducers, binders, tackifiers, and humectants.

Corrosion and Scale Control for Cooling Water

Nalco Water's corrosion and scale inhibitors feature traced chemistries designed for use with 3D TRASAR™ control systems. 3D TRASAR products are part of an innovative water treatment program that uses proven technology to prevent operational problems. 3D TRASAR compensates for both routine and special causes of system variation. 3D TRASAR programs provide a return on your investment through their unique control and diagnostic capabilities. With 3D TRASAR technology control, your system is monitored and feed rates are controlled for optimal, cost-effective performance.

Cooling Water Bio Control

Cooling towers are constantly exposed to environmental contaminants and bacteria. This requires a rapid response, accurate detection and a tailored program to control biological growth. Nalco Water offers a complete line of oxidizing and non-oxidizing biocides, algaecides and biodispersants that are effective in a variety of cooling water applications, including open recirculating cooling towers, once-through cooling systems, closed loop cooling systems, air washers, cooling ponds, thermal energy storage tanks and pasteurizers.

Featured Transportation Solution for Paint Detackification

During the last decade, the Automotive industry has increasingly demonstrated a strong commitment to corporate social responsibility. Many programs and procedures have been put in place to reduce the consumption of natural resources and associated emissions and waste. Today, more than ever, the challenges of the global economic environment demand that the industry must work even harder to meet sustainability targets and financial goals.

Every automotive plant has environmental management practices in place which aim to reduce freshwater use and minimize waste production. Effective paint detackification is critical to clean booth operations, increased return water and minimized sludge haul-off. Optimized paint sludge solids increase recycled clean booth return water which reduces total water consumption. Higher paint solids also result in less waste volume and weight, reducing waste contribution to the environment and the total cost of waste management.

Keeping the total cost of operations and performance at the forefront of sludge management, Nalco Water paint detackification products and programs have been successfully implemented in over 35 North American automotive plants.
