Application of Porous Ceramic Filtration on Ballast Water Treatment
Abstract:
Ballast water has been detected to be a great threat to marine ecosystem and human beings for threatens from biological invasion. Filtration is a kind of optimising primary method in ballast water treatment. However, so far no suitable filter has been applied considering effectiveness, economy, and resistance. A novel wall-flow structure porous ceramic filter (PCF) was adopted to combine with UV radiation. To evaluate the PCF, three types of indicator algae were filtered at different flow rates and initial alga densities. The results showed that up to 100% removal effciencies can be obtained on alga greater than 10µm and less than 50µm at the pointed alga density. The mechanism behind high removal efficiencies and high velocity were revealed as well.
