Piedroba presents paper at third International Symposium on Bioremediation and Sustainable Environmental Technologies.

Piedroba's Principal and CEO Dr.Luis Prieto-Portar has presented a paper on the Experimental Cryogenic Dewatering of Dredged Sediments at the Third International Symposium on Bioremediation and Sustainable Environmental Technologies. The Conference was being held in Miami on May 19-21, 2015.


The paper presented by Piedroba discussed the viability of cooling down the carrier water to  close to freezing, as a viable method of dewatering dredge slurries. In warmer climates, both turbulence and loads of solids are two of the factors  mainly contributing to turbidity. Another observation is that most dredge slurries have brackish carrier water. 

Dr. Prieto-Portar was able to summarize the results of preliminary experiments that used super cooled batches of hydraulically dredged slurries and noted some of their rheological properties. ​
