Oil / Water Separator Overview:

Designed according to API 421, Basiia Oil / Water Separators combine state-of-the-art separation, skimming and sludge transport technologies into a highly efficient primary oil separation device.

Removing the bulk of free oils and greases from the plant wastewater stream reduces overloading and other problems in downstream treatment processes. Basiia Oil / Water Separators are the right choice for general refinery wastewater, tank wash, bilge and ballast water, desalter waste, as well as storm wastewater run-off.

Basiia unique ability to combine a vast experience base in liquid solids separation technology delivers the highest level of process performance and unsurpassed equipment quality.

Basiia Oil / Water Separator internals are easily configured to fit existing tanks for an effective retrofit, improving performance and extending the life of the equipment.
