Q: I have green sludge collecting on the filters in my nickel plating bath. What is it, and what can I do to prevent this from happening in the future?

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

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

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

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. 

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

Precision cleaning is critical for finishing aerospace oxygen system parts.

Cabinet maker says powder coating on wood offers more benefits.

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.
