In order to comply with IMO standards a high dose of chemicals is necessary. Critics say that this way of solving one problem just creates another. It also takes quite some time for the chemicals to become effective and requires great logistic efforts.

Thus the advantages of chemical-free treatment are quite obvious as it avoids time delay and no hazardous mate­rial must be stored or handled. It is non-dangerous to the crew and no repeated expenses are to be faced for its operation. A further benefit is that the system forms a part of the vessel.
