Catalytic systems and methods for treating process streams are disclosed. Catalytic wet oxidation and hydrolysis techniques may be used to treat one or more undesirable constituents. Methane may be produced in connection with at least some embodiments.

Catalytic systems and methods for process stream treatment

Catalytic systems and methods for treating process streams are disclosed. Catalytic wet oxidation and hydrolysis techniques may be used to treat one or more undesirable constituents such as HPAM and KHI. Methane may be produced in connection with at least some embodiments.

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.

Composite media for water treatment processes and methods of using same

The present invention relates generally to a system and method for treating wastewater in a filter media apparatus having a draft tube system. The filter media may be walnut shell media.

Systems and methods of removing sulfur from a gas stream comprising hydrogen sulfide (HS) is provided. The systems and methods may utilize iodine to remove sulfur from the gas stream. In certain systems and methods, the iodine may be regenerated. In particular, the present systems and methods may be capable of reducing sulfur content in a gas stream comprising hydrogen sulfide HS gas to levels that are undetectable.

A wastewater treatment system is provided comprising a biological reactor having a separation subsystem, a suspension system and a membrane operating system. The separation subsystem is constructed and arranged to maintain adsorbent material in the biological reactor with a mixed liquor. The suspension system is positioned in the biological reactor and is constructed and arranged to maintain adsorbent material in suspension with mixed liquor. The membrane operating system is located downstream of the biological reactor and is constructed and arranged to receive treated mixed liquor from the biological reactor and discharge a membrane permeate. In addition, a wastewater treatment system is provided comprising a first biological reaction zone, a second biological reaction zone and a membrane operating system. The first biological reaction zone is constructed and arranged to receive and treat the wastewater. The second biological reaction zone includes a separation subsystem and is constructed and arranged to receive effluent from the first biological reaction zone. A suspension system for adsorbent material is provided in the second biological reaction zone. The membrane operating system is located downstream of the second biological reaction zone and is constructed and arranged to receive treated wastewater from the second biological reaction zone and discharge a membrane permeate.
