Produced Water Filtration

Jan. 19, 2018


Typical extraction of oil and/or gas also results in produced water. Produced water is naturally occurring water found with the petroleum related materials. This water is usually highly contaminated with brine (salts, hydrocarbons, heavy metals) that need to be disposed of for environmental reasons. 

The “produced water” contains varying levels of solid contaminants including iron oxides, iron sulfides and asphaltines (tar-like particulate) that need be eliminated prior to disposal or injection. Produced water filtration must remove solid contaminants efficiently and provide consistent filtration performance. Disposal of the produced water requires that the water quality meet local standards for Total Suspended Solids (TSS). When re-injecting produced water, any bypass or unloading of contaminant into the high pressure injection stream can cause injection well plugging or fracture, requiring.


5 Micron Liquid Filter Bags, produced Water processes have high impurity content including large amounts of soft deformable particles. Surface filtration systems such as automatic backwash filters, metal filters and membrane filtration are not suitable. In these applications, a high dirty-holding disposable filter element is the most appropriate solution.

5 Micron HFM Series High Flow Pleated Cartridges, Oil adsorption bags are made from high-precision polypropylene microfibers. It has excellent oleophilic properties, quick adsorption, high oil absorption capacity, acid & alkali resistance. It is the preferred choice for removing oil from produced water.
