Oil plays a part in just about every industrial process on
earth. While oil can play crucial and beneficial role in industrial operations, it can also cause
many challenges once it has served its purpose and ends up in the wastewater stream.
To increase the efficiency of wastewater treatment processes and maintain environmental compliance, organizations must first remove the oil
before repurposing it or the water, before discharging water to the municipality, and before...
Whether your power plant is coal-fired, gas-fired,
hydroelectric or nuclear, petroleum-based products like fuel, hydraulic fluid and lubricating greases and
oils are critical to operational success.
Supporting numerous lubricant connections, bearings, hydraulic seals and moving equipment parts, such as
pumps, conveyors, feeders, scrubbers, cranes, turbines and more—it’s inevitable that these petroleum-based
products will find their way into the process, cooling, or cleaning water that flows throughout a
plant—posing operational challenges.
Typically, this oily or greasy water flows to one...
Removing oil from any industrial process is important. Animal fats, grease and petroleum-based oils all have
a significant impact on both overall maintenance and environmental compliance of an operation.
Hence why oil refineries, chemical plants, steel mills and many other types of companies throughout the world
use oil/water separators. This flow-through device takes advantage of the fact that oil has a lower density
than water, causing it to float on the water’s surface, to separate oil from the wastewater.

Oil skimmers are very effective in removing oil from wastewater before discharge but are also perhaps the
most efficient and economical approach.
Despite these advantages, oil skimmers are not found in every power plant. Some plants rely on less-efficient
oil removal procedures, failing to recognize that even a single release could cost more money than upgrading
a facility to modern oil-skimming equipment.
An oil skimmer (Figure 8) efficiently removes oil from water continuously and puts it into a collection...
