“…The ballast water contains a variety of biological materials, plants, animals, viruses, and bacteria of non‐native, nuisance, and exotic species, causing extensive ecological and economic damage to aquatic ecosystems, along with serious health hazards. Thus, ceramic filter for the ballast water treatment is getting more important 50 …”

The sustainable development goals (SDGs), including 17 goals and 169 targets, were adopted unanimously by the United Nations General Assembly in 2015.The aims are to end poverty, protect the planet, and ensure peace, health, and prosperity of all people over the world. Toward the SDGs, human beings must effectively utilize the global resources, such as (1) oceans, seas, rivers, lakes, and so forth that supply us with water and aquatic resources; (2) land, ground, and soil where we can raise agricultural crops and livestock; (3) forests and woods that provide us with lumber and paper and convert carbon dioxide to oxygen; and (4) fossil fuel and mineral resources, which are essential to our modern lives. The use of macroporous ceramics is definitely conducive to the solutions to achieve the SDGs, because it can help solve many of the related technical issues. This review addresses macroporous ceramics primarily for filtration and purification, agriculture and fisheries industry, thermal managements, sensing devices, and constructions, which contribute to achieving SDGs.

“…In our previous works, such porous ceramic filter has been proved to have higher removal rates on phytoplankton in ballast water [13][14]. This paper will further study the necessity and superiority of the combination of porous ceramic filtration and UV radiation (PCF&UV), and the installment and operation costs are discussed as well, to approval the technical and economic feasibility of PCF&UV treatment.…”

Biological invasion of ballast water has been detected to be a great threat to marine ecosystem and human beings. However, so far less suitable method has been developed to obtain an effective, economic, safe, operational and clean onboard treatment method of ballast water. Hence porous ceramic filtration and UV radiation (PCF&UV) combination treatment is studied in the paper to propose a novel way to solve the problem. Targeted for the IMO convention, alga removal efficiencies and bacteria inactivation efficiencies were tested at different alga density and different flow rate. The results showed that 100% targeted alga can be removed and 100% marine bacteria can be inactivated at the appointed alga density. Optimal flow rate of 7m 3 /h is proposed for a 6L porous ceramic filter according to the results. The mechanism behind high removal efficiencies and inactivation efficiencies were researched as well.

“…In the preliminary tests at flow rates of 1-10 m 3 $h -1 , MPCF&UV showed high performance on removing small algae such as Chlorella, Nitzschia closterium and Platymonas helgolandica and on inactivating oceanic bacteria [12,13]. Based on the previous work, an onshore MPCF&UV treatment system with maximum flow rate of 80 m 3 $h -1 was installed, and a set of tests were conducted to study the technical feasibility of MPCF&UV treatment by evaluating durability of the system and effectiveness on both indicator organism and native seawater.…”

To fulfill the requirements of Guidelines for approval of ballast water management system (G8), a set of onshore ballast water treatment equipment utilizing micro-pore ceramic filtration (MPCF) and UV radiation (MPCF&UV) system was designed and set up with a maximum flow rate of 80 m 3 $h -1 . Technical feasibilities of MPCF&UV system were evaluated in three areas: removal efficiencies of indicator organism and oceanic bacteria, perdurability of a ceramic filter, and application on native seawater. The results showed that no indicator organism (Dunaliella) or oceanic bacteria was detected after treatment of 20 L MPCF and UV radiation at 1.3Â 10 4 μW$s$cm -2 . A 20 L ceramic filter can run continuously for 5.3 h at the flow rate of 15 m 3 $h -1 before its pressure drop up to 0.195 MPa. The removal percentage of total plankton amounts were 91.9% at a flow rate of 70 m 3 $h -1 by 80 L MPCF and UV radiation at 1.3Â 10 4 μW$s$cm -2 .
