Bilge oily water is bilge sediments, which are formed on all types of vessels as a result of leakage of water, and of ship equipment, feed . includes sea water that ensures operation of the equipment aboard.  Getting into ship’s service area it mixes with the contaminants. Waste gradually accumulates in the engine rooms of ships. is also formed in various industries, as well as at tank farms and filling stations.

is denoted by the second class of environmental risk along with cement dust, electrolytes, sulfuric acid and other aggressive substances. Petroleum products being in the water in different phase-dispersed states, gradually lead to the formation of “dead zones” in which the oxygen level is considerably reduced. Discharge of into the environment is prohibited by law in Russia and all civilized countries.

Many methods of bilge treatment have been invented and used. The most effective of them are:

  • Flotation treatment
  • Multistage cleaning with pressure aeration by purified recirculating water
  • Ultrasonic cavitation
  • The method of thermal oxidation of emulsified petroleum products
  • Centrifugal purification
  • Separation precipitation

The methods available in the market have one common disadvantage: inefficiency and inability to re-use products.

Laboratory of filtering materials “E-KO” has developed and is successfully introducing filtration units based on a nanoporous composite material “E-KO” which separate into water and .
