New role of hydrocyclone in ballast water treatment

2018-7-1  Laboratory experiments were carried out to determine the effects of an integrated ballast water treatment system on the viability of test species of phytoplankton (Tetraselmis suecica) and zooplankton (Artemia salina cysts and nauplii).The effects of two components of the treatment system were tested: cyclonic separation in the hydrocyclone (HC) and radiation in the ultraviolet (UV) reactor.

This processed clear-water fraction of sea-water provides a sterilized source of water to be used as ballast required by ships for stability during trans-oceanic journeys.

Full-Scale Design Studies of Ballast Water Treatment

2015-6-16  Ballast water is a major contributor to the transfer of harmful organisms and pathogens. Potential economic impacts and impacts on human health and the ecology are very significant and cannot be ignored. A substantial amount of scientific study has been devoted to the problem of invading species that are carried in ships’ ballast water.
