Navy Trims Ship Painting Protocols
9 significant changes to painting protocol during shipbuilding in a pilot project to increase efficiency, save money.
- Applying powder coating directly to metal on interior components such as electrical boxes;
- Applying interior liquid coatings on interior components without requiring a primer;
- Applying underwater hull coatings over moderate rust;
- Reducing surface preparation on deck tie-downs;
- Using galvanized fasteners instead of painting bare steel fasteners in ventilation ducting;
- Not painting areas covered by docking blocks during final coating application;
- Applying high-solid, rapid-cure tank coatings that are tinted to bilge colors in new construction submarine bilges; and
- Raising the allowed relative humidity in buildings in which tank coatings are applied.

NASF/AESF Foundation Research Project #122: Electrochemical Approaches to Treatment of PFAS in Plating Wastewater - 10th Quarterly Report
The NASF-AESF Foundation Research Board selected a project addressing the problem of PFAS and related chemicals in plating wastewater streams. This report covers the 10th quarter of work (April-June 2023). Here, we examine the effect of surface fluorination of Ti4O7 anodes on PFAS degradation performance in terms of energy performance as well as formation of chlorate and perchlorate when chloride is present in the solution. The full paper on this work can be accessed and printed at short.pfonline.com/NASF24Feb2.

NASF/AESF Foundation Research Project #122: Electrochemical Approaches to Treatment of PFAS in Plating Wastewater - 12th Quarterly Report
This NASF-AESF Foundation research project report covers the 12th quarter of project work (October – December 2023) at the University of Georgia. In our previous report, we described our work on performance and effect of surface fluorinated Ti4O7 anodes on PFAS degradation in reactive electrochemical membrane (REM) mode. This quarter, our experiments involved utilizing porous Ti4O7 plates serving both as anodes and membranes. Tests compared pristine and F-18.6 Ti4O7 anodes at current densities of 10 mA/cm2 and 40 mA/cm2. This 12th quarterly report discusses the mechanisms of the effects on EO performance by anode surface fluorination.

NASF/AESF Foundation Research Project #120: Electrochemical Destruction of Perfluorooctanesulfonate in Electroplating Wastewaters – January – December 2023
This NASF-AESF Foundation research project report covers quarterly reporting for the year 2023 at the University of Illinois at Chicago. The objective of this work is to utilize a cost-effective reactive electrochemical membrane (REM) for the removal of PFAS from synthetic electroplating wastewater. Discussed here are the oxidation of PFOA with three different catalysts, development of a method for detecting PFAS, as well as work on 6:2-fluorotelomersulfonic acid (6:2 FTS) and electrodeposited bismuth/tin oxide catalysts.
