Metering pumps for chemical and petrochemical chemical companies are among the biggest water users

Metering pumps for chemical and petrochemical chemical companies are among the biggest water users on the planet, investing billions each year in water acquisition, treatment and disposal. They require almost 3 pounds of water for every pound of chemical produced, and more than 70 percent of this water must be cleaned and treated before it can be discharged, after being used only once. Properly managing water and wastewater treatment can produce savings of 1 to 2 percent annually, which, for companies like DowDuPont or BASF, can add up to millions of dollars each year.

The pumping infrastructure used to treat water is a good place to find efficiencies, since the largest chemical producers deploy thousands of pumps in each facility. While many of these pumps are transfer pumps, an examination of the chemical metering pumps used to make products and treat process water reveals opportunities to save costs. The four most common chemical metering pump applications in chemical manufacturing plants include:

• Dosing precise volumes of chemicals to make products
• Pre-treating the process water to boost quality and efficiency
• Dosing anti-scaling chemicals to clean and protect plant infrastructure
• Post-treatment of the wastewater prior to disposal
