Paper Mill’s Power Plant Saves Water – Ecolab Case Study (2018)

This case study looks at Nalco Water’s use of 3D TRASAR Technology to generate an annual water savings of 14,430 m3 for a paper mill’s power plant.

  • Learn how Nalco Water helped a DS Smith power plant reduce water consumption and decrease the plant’s environmental impact.

Detailed Description



DS Smith, a global manufacturer of sustainable corrugated packaging materials and specialty papers, operates a power plant in Porcari, Italy, that produces electricity for the power grid and steam for an adjacent paper mill.

The power plant was experiencing ongoing challenges with intermittent, high levels of iron corrosion particles in its steam generation system. This was negatively affecting its boilers as well as its productivity, profitability and overall operations.


Enter Nalco Water’s team of experts. They identified the source of the magnetite loss and implemented 3D TRASARTM Technology to reduce iron oxides in the boiler water, which greatly reduced the risk of the plant being taken offline. It also led to reduced boiler water blowdown, erosion and corrosion, which lowered maintenance costs and cut water consumption, decreasing the plant’s environmental impact.
