A filter includes a filter assembly deployed within a pressure vessel. The filter includes a series of filter configurations arranged along a central flow path connected to an outlet. Each filter configuration has filter screens overlying at least one filtrate channel which directs filtered fluid to the central flow path, A partition is deployed within the pressure vessel so as to subdivide the pressure vessel into a first filter chamber and a second filter chamber, each containing a number of the filter assemblies. A flow diverter is deployed in the central flow path for diverting a flow of filtered liquid passing along the central flow path from the first filter chamber so as to flow outwards from the central flow path to undergo a second filtering in the second filter chamber. Also disclosed is an outlet flow throttling arrangement to avoid overload of a backwash cleaning system.

Methods and systems for removing water vapor from a feed gas prior to further processing the feed gas according to a downstream PSA process are described. The feed gas can include CO.sub.2 and/or CO and/or H.sub.2 and the PSA process can be used to separate components of the feed gas from one another, for instance, for CO.sub.2 capture. Light product off of the PSA process is utilized to regenerate desiccant of a dryer used in the water vapor removal process that is carried out prior to the feed gas entering the PSA process. The water vapor removal process can be heated by providing thermal energy directly to the dryer and/or to a regenerating stream that regenerates the desiccant of the dryer. The thermal energy can be low cost energyfor instance, waste heat off of a system that provides the feed gas.

A system and apparatus configured to facilitate on-site treatment of wastewater from a residence is described. The system is configured to immediately treat wastewater as it is generated, on an as-needed basis, and works to remove undissolved down solids and reduce dissolved materials concentrations to a uniform level prior to transmission of the wastewater to municipal waste water treatment facilities and/or any non-drinking application. The system employs a two-stage treatment apparatus where the first stage is configured to pre-grind and decompose undissolved solids of the wastewater and the second to reduce dissolved materials concentrations. The first stage uses turbidity meters, and the second stage uses pH, BOD and conductivity to ensure a uniform output from each stage. A fast decomposer has rotating filters which operational modes ensure that the filters do not become clogged with solids in a cake form simultaneously.

A filter unit for filtering microparticles from a feed liquid containing microparticles. The filter unit comprises a filter chamber extending along an axis, and comprising opposing first end and second end walls and at least one sidewall extending therebetween and both first and second end walls are coincident with the axis. The filter unit also comprises a filter cage contained within the filter chamber and configured to rotate about the axis, the filter cage comprising one or more than one filter media for filtering microparticles from the feed liquid. The filter unit also comprises an inlet configured to pass feed liquid through the first end wall into the filter chamber. The filter unit also comprises an outlet in the filter chamber for passage of filtered liquid out of the filter chamber. The filter unit also comprises a drive shaft configured to drive rotation of the filter cage, the drive shaft extending from the first end wall of the filter chamber to the filter cage. The second end wall is or comprises an opening therein and a removable lid, in a first configuration the opening is closed by the removable lid so that feed liquid cannot pass through the opening, in a second configuration the lid is removed from the opening so that filtered microparticles are extractable from the filter chamber through the opening. The present disclosure also relates to a textile treatment apparatus comprising the filter unit, to the use of the filter unit and the textile treatment apparatus, and to methods of filtering microparticles from feed liquid containing microparticles.
