A water treatment device construction structure having a grating room and a method for constructing various water spaces/waterscape facilities having the same coupled thereto are disclosed. The structure relates to a buried water treatment device for treating operation water such as tap water, groundwater, rainwater, and surface water through an environment-friendly method. A water treatment device construction structure having a grating room is coupled to civil engineering/landscaping facilities, or to fish farms that are to be constructed in view of the purpose of construction and productivity. The water treatment facility having a reservoir coupled thereto is provided in a predetermined position below facilities or on the lower-end or peripheral portion thereof in a buried/underground type. Accordingly, there is no burden in site selection; a large amount of operation water can be stored without degrading the aesthetic landscape; and natural energy can be used preferentially.

The disclosure relates to devices and systems for configurable, contaminat-specific water filtration and treatment. In particular, the disclosure relates to a contaminant-specific configurable and modular horizontal water filter and a water filtration system, comprising modular housings, each housing defining a plurality of reconfigurable compartments operable to accommodate contaminant-specific filtering units.

A capture unit for use with an antimicrobial application unit may include an upstream filter and a downstream filter. The upstream filter may be positioned to receive effluent from the application unit and to filter solid components from the effluent. The resultant upstream effluent filtrate may then be passed downstream to the downstream filter. The downstream filter may be used to filter an antimicrobial component from the upstream effluent filtrate and the resultant downstream effluent filtrate may be suitable for disposal as wastewater discharge. The antimicrobial is preferably a quaternary ammonium compound, is more preferably an alkylpyridinium chloride, and is most preferably cetylpyridinium chloride.

A fluid management system including an inlet configured to receive pre-processed fluid is provided. The system includes a filtering apparatus configured to remove contaminants from the pre-processed fluid. The filtering apparatus includes a plate having a first opening. A first manifold pipe is disposed on the plate and includes one or more perforations and a second opening at least partially aligned with the first opening. A second manifold pipe is disposed on the plate and includes one or more perforations. Filter media is disposed between the first manifold pipe and the second manifold pipe and is configured to separate the contaminants from the pre-processed fluid. The system also includes an outlet coupled to the second manifold pipe to receive processed fluid from the filtering apparatus.

Filters and cigarettes include an activated carbon sorbent capable of selectively removing nitric oxide from mainstream tobacco smoke. Methods for making cigarette filters and cigarettes using the activated carbon sorbent and methods for treating mainstream tobacco smoke produced by smoking a cigarette including the sorbent are also provided.

A device for separating and extracting suspended solids and particles from a fluid is shown. The device can include a hydro-cyclonic process unit, a variable geometry vortex process unit, a reverse coalescence and flocculation process unit and a fixed geometry vortices separator process unit. The fluid to be treated can enter the device through a fluid inlet and travel and recirculate through the several process units. The process units can collectively induce vorticose separation of the fluid and separate suspended solids and particles within the fluid. The suspended solids and particles can then be extracted from the device via one or more extraction fluid outlets. After the desired amount of suspended solids and particles has been removed, the processed fluid can be discharged from the device.

A rotary fluid filter including a filter body rotationally mounted within a housing. The housing having a front cap having a main fluid inlet and a backwash outlet, a rear cap having a main fluid outlet and a backwash inlet. The filter body having a front face, a rear face, and a plurality of fluid flow passages each extending through the filter body between the front face and the rear face and having a filter received in each fluid flow passage. The filter body operable to rotate with in the housing such that, for each fluid flow passage, as it is aligned with the main fluid inlet a main fluid is received therein, as it is aligned with the main fluid outlet the main fluid is discharged therefrom, and as it is aligned with the backwash inlet and the backwash outlet a backwash fluid is received therethrough.

A fluid management system can include a first chamber, a diffusion plate positioned in the first chamber configured to receive fluid and to direct the fluid along a bypass fluid flow path or a primary fluid flow path, a riser pipe positioned within the first chamber that conveys fluid from the diffusion plate into a second chamber, and a filtering apparatus positioned in the second chamber. The filtering apparatus can include a plate having a first opening, one or more modules coupled to the plate having one or more perforations and a second opening corresponding to the first opening, and filter media disposed adjacent to the one or more modules, and a slab positioned above the filtering apparatus.
