Date Sep. 13, 1984.In order to make better use of tankers transporting oil from the oil-producing countries to oil-consuming countries, attempts have been made at transporting drinking water from the latter countries to the oil-producing. These attempts have been fruitless since it has been impossible to reduce the oil content to an acceptable value. By using a filter consisting of units (4) of foam plastic with perforated closed cells it has been possible to achieve values below that considered acceptable.
