MegaRust 2010 has Come and Gone
From the comments we received, MegaRust 2010 was another success. San Diego is, of course, a wonderful setting. The fact that they were running their big marathon during the opening day was interesting for some and a bother for others. No one complains about the food, though–especially the food in Old Town, and particularly that [...]

MegaRust 2009
Mega Rust Workshop Date : 2009-03-12 2 Separate Workshops on “How to Inspect for Flash Rust” To replace the description sent out on 2009-03-09 Contact Person: Lydia Frenzel Frenzel tried to cover two workshops with one write-up. This was confusing to some people. The tag line “Practical Solutions for Practical Problems” reflects Dr. Frenzel’s approach [...]

Just Wastewater
The objective of this project was to investigate methods for treating the ballast water from naval vessels that have compensated fuel tanks. With an oil and water interface, there is some mixing of fuel and water so that free oil and emulsified oil are part of the ballast water. However, most shipyards that occasionally deal [...]

Copper and Zinc Waste
This regulatory action lead to an intensive research effort to develop a treatment method for ship s wash water waste stream that could consistently remove TBT to levels below this discharge standard. Coagulation studies have concentrated on evaluating the performance of two metal-salt coagulants and their ability to remove copper and zinc with the large [...]

Stormwater and Heavy Metals
Even with the most sophisticated and rigorous best management practices (BMPs), some heavy metals are invariably transported into storm water collection systems. Storm water discharges into adjacent receiving waters are facing increasing regulatory compliance requirements which include not only additional BMPs, but chemical monitoring programs. In addition to material selection, placement of the porous adsorber [...]

Removing Tributyltin
The purpose of this study is to identify practical technology that can be used by shipyards to remove tributyltin (TBT) from large volumes of water to levels below 50 parts per trillion. Procedures for treating wastewater at the Livermore facility start with the addition of iron (II) chloride to remove sulfides and to promote settling. [...]
