API (American Petroleum Institute) separators are frequently used in the treatment of refinery wastewater that has been contaminated by oil and oil-bearing sludge. Separators use the difference in specific gravity to allow heavier liquids to settle below lighter liquids. The lighter liquid is skimmed off, while the heavier liquid remains behind.

Wastewater treatment plants (WWTPs) use large, heated digester tanks to remove and dispose of solid waste material. Here, bacteria break down the material, producing digester gas in the process. Methane is a primary component of anaerobic digester gas (ADG) and a large wastewater treatment plant can produce roughly one million cubic feet of this gas each day.

Saudi Aramco has adopted a policy of minimizing its extraction of groundwater and the use (and associated expense) of desalinated seawater for process water use. As an alternative, they are actively investigating sustainable methods and technologies that will allow wastewater reuse, either as cooling water makeup and/or boiler feed water. Typically, reverse osmosis treatment of biologically treated effluent is required for reuse; however, this leads to excessive organic fouling of reverse osmosis membranes due to recalcitrant COD remaining in the treated effluent.

Since the January 1, 2010, implementation of the International Maritime Organization's (IMO's) MEPC.159(55) effluent discharge regulations, many marine and offshore oil and gas professionals are now more closely examining the various logistics of solids/sludge handling requirements associated with commercially available marine sewage treatment plants (STPs) in order to avoid potential health, safety, and environmental issues.
MIOX on-site chemical generators are capable of high treatment rates so you can recycle the most oil and gas water per day. Eliminate hydrogen sulfide, treat out SRBs and APBs, reduce iron that causes scale, and reduce chemicals on the road.
The process of fracking produces heavily contaminated wastewater, or produced water. This video shows how ceramic ultrafiltration membranes can treat produced water for reuse in future fracking operations, for irrigation, or for discharge to a receiving stream.
A plant in the southwest U.S. commissioning a wastewater plant utilizing proprietary technology for the removal of benzene, toluene, and xylene, or BTX was experiencing challenges with throughput and elevated operational costs due to the presence of particulate contaminants.
