Castellón, Spain (PortSEurope) May 15, 2019 – The Institute of Ceramic Technology (ITC) of Castellón has measured and confirmed the efficiency of the dust-trap screens installed by Autoridad Portuaria de Castelló (APC – Port Authority of Castellon) to protect the neighbouring areas from pulverulent particles derived from the loading and unloading of solid bulk.

The efficiency has been defined as the percentage of PM10 retained by the screen, so that an efficiency of 100% would indicate that the screen retains all the PM10 emitted. The study observes that the conditions of wind speed and direction, together with the height and distance to the screen, affect “significantly” the effectiveness achieved, as reported by Castellón port authority.

Considering the emission focus at different heights and distances from the screen, it captures an average of 25% of the particles emitted, “which is a good result that amply justifies the investment”, explained the president of port authority, Francisco Toledo.

The efficiency can reach up to 50% with low and near-screen emission sources. In addition, the ITC concludes that a “remarkable” effect is observed at the leeward of the screen even at great distances, over 200 meters, especially in terms of PM10 concentrations.

The study also analysed the efficiency of the screens when the material deposits are located in the opposite part of the wind. In this case, the dust-trapping screen reduces the wind speed and favours the deposition of the particles in suspension and, therefore, improves the quality of the air.
