According to various aspects and embodiments, a system and method for treating a feed stream comprising hydrocarbons, suspended solids, and an aqueous-based liquid is provided. The systems and methods may utilize a stratified multi-media bed that includes at least one layer of a composite media comprising a mixture of a cellulose-based material and a polymer. According to certain aspects, contacting the feed stream with the stratified multi-media bed comprises coalescing and filtering the feed stream. According to at least one aspect, the systems and methods include a draft tube positioned within the stratified multi-media bed that may be utilized for backwashing the layers of filter media.

Multi-media stratified filtration

Systems and methods for treating a stream comprising hydrocarbons and an aqueous-based liquid are provided. The systems and methods may utilize a media composite comprising a mixture of a cellulose-based material and a polymer. In certain systems and methods, the media composite is capable of being backwashed. The stream comprising the hydrocarbons and aqueous-based liquid may be separated by contacting the stream with the media composite. In certain system and methods, the stream comprising the hydrocarbons and aqueous-based liquid may be coalesced by contacting the stream with the media composite.
