Question: We use a bleach solution to treat cyanide and a caustic solution to raise pH in our wastewater pretreatment system.

PPG has an existing goal to reduce greenhouse gas emissions intensity by 15% by 2025 from a 2017 baseline, reportedly achieving a 9.7% reduction in 2021.

Regulation of PFAS chemicals continues to increase — here are some steps finishing operations can take to prepare.

Belzona 5815, a solvent-free containment-grade coating with enhanced flexibility, is designed to protect concrete chemical containment areas and bunds.

Maximilian Kessler from SurTec explains new practices for industrial parts cleaning, metal pretreatment and decorative electroplating in the medical device industry.

An AESF Foundation summer research grant provided an excellent opportunity for a PhD student to learn how to use chemical engineering fundamentals to scientifically characterize an electroplating process through integrated dynamic modeling and simulation, and how to develop digital twin (DT)-based virtual plant that can be of any process configuration.  This is a critical step for the investigation of new technology development for smart and sustainable manufacturing in the surface finishing industry.

This NASF-AESF Foundation research project report covers the seventh and eighth quarters of project work (October 2021-March 2022) at the University of Illinois at Chicago.  The major activities reported are: (1) to investigate 6:2 FTS oxidation, a common replacement compound for PFOS in the electroplating industry, and (2) PFAS oxidation in both a wastewater sample procured from an electroplating facility and in synthetic solutions. 

Guidelines to help prevent the loss of nickel and its salts from the finishing shop.

Zachary Beckman of Haviland Enterprises Inc. discusses proper filter press maintenance for optimization of wastewater treatment systems.

Over many years, well-regarded AESF/NASF contributor Jack Dini wrote a series of fascinating columns to Plating & Surface Finishing, under the title Fact or Fiction?.  He hasn’t slowed down in 2021.  Here, he notes that more research studies are revealing that a little bit of some toxins can be quite helpful to human health. The following shows a number of examples.
