Purification treatment in compliance with IMO regulations (shipping)

Oil water separation

In addition to wastewater treatment, Triqua International also provides oil/water separation processes. These processes are usually executed with a plate separator system. Regulations are becoming more stringent which dictates, in order to remove also emulsified oil, the use of the UF membrane technique, .

Our systems can be used on board ships, within the offshore industry and at harbor reception facilities. With this system, the bilge water is treated so that a high-quality effluent is guaranteed in conformity with IMO regulations (MEPC 107.(49)).

Oil/Water separation can also be applied in the oil and gas industry. An excellent material for the production of a Ceramic membrane was recently found ; the so called SiC-material. This type of membrane withstand high temperatures and pressures, and can operate in a broad pH-range.

Advantages of oil water separation

The process of oil water separation results in a number of distinct advantages:

  • Post-treatment of direct discharge into the sea (ships) is possible 
  • Post-treatment of discharge into the sewer or open waters (land) is possible 
  • Low maintenance costs 
  • Low chemical cost 
  • Compact system

Oil water separation in practice

Shipping

In collaboration with the Royal Dutch Navy, Triqua International has completed a project to treat bilge water from navy vessels and pressure water from submarines. The bilge and pressure water has a high concentration of free oil and is further concentrated (200 to 300 times) using ultra filtration membranes. The oil-rich concentrate is sent for incineration and the permeate is treated in a Membrane Bioreactor. The MBR effluent is subsequently discharged into the harbour.

Land installation:

 SEIC (The Sakhalin Energy Investment Company) (Gazprom, Shell, Mitsui and Mitsubishi Ltd.) For this project we built a special unit that is able to meet the local requirements. First, the solids are flocculated in the water, after which a special plate filter is used to discharge the oil and excrete the solids simultaneously. Next, two safety filters are deployed, after which the water has been through its first purification phase. The entire system has been built in a sea container, thereby reducing transport problems to a minimum.
