Clay Sprays May Control Harmful Algal Blooms

01.10.2002


Harmful algal blooms, or HABs, can harm fish, birds and even people who are exposed to the toxic algae. HABs come in many forms, including a red tide that regularly affects Florida waters, a brown tide organism, and Pfiestera piscicida, an algae associated with fish kills. Scientists are unsure of exactly what causes the blooms, but a Woods Hole Sea Grant research team may have come up with a way to treat the increasingly common occurrences. Don Anderson and Mario Sengco are testing the use of clay to manage and control HABs. Clay, mixed with seawater, is sprayed over the algal bloom, where it binds with the harmful organisms and sinks to the bottom. In laboratory experiments meant to mimic field conditions, results showed that the clay removed 80 to 90 percent of the toxins in 2-hour treatments.



Korea and Japan have used clay to control HABs periodically. In Korea clay is used mainly in aquaculture operations, which provide about 30 percent of Korea’s fish. The concept has not caught on yet in the U.S., mainly due to water quality concerns. The WHOI project uses only native clay types, many of which come from the Florida coast in the Gulf of Mexico. Further research on water quality issues and the future feasibility of clay use to treat HABs is currently taking place.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
