Filters Help Preserve 17th Century Shipwreck

To most people, water clarity is important, but the nautical
archaeologists at Texas A&M University know that to rebuild a 300-year-old
ship, it is essential. They needed filtration equipment that was up to the
task.

Filters Help Preserve Shipwreck

The Belle, a small 17th-Century French frigate, was discovered in July 1995 in Matagorda Bay, Texas, in 12 feet of water. The delicate nature of the waterlogged wood meant it could not be allowed to dry out. The water storing the ship must be free of particulate, algae and bacteria and may contain only chemicals safe for the staff to work in. Water also must be kept particulate-free in order for the conservation solution to work properly.

Process Effectively Strips Hydrogen Sulfide Gas From Wastewater

Hydrogen sulfide is a common component in wastewater treatment plant off-gases (e.g., biogas) and waste gases from certain industrial processes. It is highly toxic and odorous. Therefore, its release into the atmosphere is regulated. In addition, it is very corrosive, which can result in costly damage to equipment and piping systems used in biogas handling. Several technologies exist for removing H2S from gas streams, but many suffer from drawbacks such as insufficient removals, complexity or high cost.

POU Options for Arsenic

The topic of arsenic has received a lot of press coverage this year, ever since the Bush administration halted the EPA’s newly issued maximum contaminant level (MCL) of 10 parts per billion (ppb). Since then, the MCL was reinstated back to 50 ppb and further discussions and studies have continued. This article will discuss some of these updates.
