IWC 23-52: The use of Definitive Screening Design (DSD) to Understand the Impact of Water Composition, Operating Conditions and Non-Phosphorus Corrosion Inhibitor Dosages on Carbon Steel Corrosion in Circulating Cooling Water Systems
Stan Baskov, Haliburton Muliti-Chem
Definitive Screening Design (DSD) was used to better understand the effects of temperature, pH, calcium and magnesium hardness and various concentrations of chlorides and sulfates on the inhibition effectiveness of non-phosphorus, corrosion inhibitor on mild steel. Statistical analysis indicates that temperature and pH are the only variables that significantly impact the rate of corrosion of mild steel. No significant difference in corrosion rate was detected during studies under various hardness, chlorides and sulfates concentrations.
IWC 23-35: Film Forming Products: Application, Corrosion Reduction, Layup Benefits, and Heat Transfer Improvement
George Patrick, Veolia
Film Forming Products (FFP) have been used in boiler/steam cycles for many years, but the benefits were limited because the application was difficult. In the last decade, the application of FFP has improved using volatile FFP to simplify the application. The benefits of the simplified application is carbon steel corrosion reduction in the boiler and steam system during operation and layup. Other benefits include heat transfer improvement, chemical reduction, and simplified equipment layup.

IWC 23-45: Wastewater Reuse and By-Product Recovery at the First ZLD in an India Viscose Plant
David Ciszewski, Veolia WTS
Grasim Nagda is the world’s largest producer of spun-dyed specialty fibre. Grasim specified and implemented a large multi-step ZLD wastewater treatment system to maximize water reuse and by-product recovery.
The plant was commissioned and fully operational in 2022. The paper describes the plant design and examines operation and performance. The paper presents data on recovered water quality, salt product purity, and process interface.
IWC 23-16: Mining Wastewater Storage Pond Treatment – 10 Years of Lessons Learned at a Remote Site with Extreme Algae Issues
Linea Miller, E.I.T., WSP E&I Canada
WSP has provided ongoing support to a remote open pit mining operation in the Canadian arctic for treatment of hydrocarbon impacted wastewater which must be discharged seasonally. Effective treatment of the impacted water has proved to be challenging due to the remote nature of the site and increased levels of organics from mining operations. This paper presents the lessons learned and how the treatment approach and system performance have changed over time.
