A separation device and method for treating effluent mixture streams including one or more liquid component(s). The device and method can utilize gravity and/or hydromechanical separation to separate non-water components from the effluent mixture. The device and method more particularly relates to an improved large capacity grease interceptor having an integrally formed double baffle sidewall within the tank reservoir to control the movement of effluent mixture within the reservoir, as well as significantly improve structural integrity of the device and ease of manufacturing and assembly.

A method, a system and an apparatus for wastewater treatment using a combination of separation of fat, oil and grease (FOG) and biological treatment for reducing the amount of fat, oil and grease (FOG) in wastewater with the aid of a liquid culture of microorganisms is provided. In particular, the technology disclosed relates to a method and process for the separation and treatment of FOG, as well as a container tank and an outlet pipe construction adapted for improving the gravimetric FOG separation process and the breaking down of FOG using microorganisms.

The present disclosure provides for devices, systems, and methods of separating PFAS compounds from wastewater leachate. After separation, the PFAS compounds can be rendered less harmful. The present disclosure provides for devices, systems, and methods that uses aeration-induced foaming to isolate PFAS from landfill leachate into a concentrated, volume reduced liquid (coalesced foam), which can be separated and treated.

A subsea production unit for subsea treatment of oil has a frame that supports an onboard multiphase separation system for separating gas and water from a wellstream containing oil. The subsea production unit also includes an onboard water treatment system for cleaning oil from water that is produced by the separation system.

Systems and methods for treating wastewater with an oil-specific viscosifier composition and separating viscosified oil, undissolved solids and/or particulates, and/or other waste materials in such wastewater are provided. The methods further include: providing wastewater that includes oil; mixing the wastewater with an oil-specific viscosifier composition to form a viscosified oil; and separating at least a portion of the viscosified oil from the wastewater to provide treated water.
