Self-supporting structure comprising a monobloc for installing cylindrical filtration cartridges therein. In one embodiment a structure provides two side panels on each side of the monobloc used for sealing the numerous passageways, at the same time, provided within the monobloc. Such a structure aims to sharply reduce the number of components required to install cylindrical filtration cartridges in a filtration plant, while keeping the same number of cartridges. Thus the invention contributes to highly reduce the investment and the maintenance costs of a filtration plant, and offers also the opportunity to reduce the operational cost of such a plant.

The present invention relates to a hollow fiber membrane module unit including a plurality of hollow fiber membrane elements to which header pipe caps are attached at both end portions, the hollow fiber membrane elements being arranged in parallel to form a row, in which the adjacent header pipe caps attached to the hollow fiber membrane elements on a permeate side are connected by a side seal connection covering an outer periphery of a contact surface, and the header pipe caps at at least both ends of the row are fixed by a support bar.

Fluid separation membrane module assembly with a vessel (7) having a tubular shape with a tubular surface and two opposite end apertures and one or more fluid separation membrane modules (12) positioned along a centerline of the vessel (7). Each fluid separation membrane module (12) comprises membrane elements configured for separating a feed flow into a residual flow and a permeate flow. Adjacent ones of the one or more fluid separation membrane modules (12) are fluidly connected together. The fluid separation membrane module assembly further comprises a feed and permeate connection assembly (6) closing off one of the two opposite end apertures of the vessel (7). The feed and permeate connection assembly (6) has a feed connector (5) and a permeate connector (3). The feed connector (5) and the permeate connector (3) are positioned off-center in the feed and permeate connection assembly (6).

A compact hydraulic manifold for transporting shear sensitive fluids is provided. A channel network can include a trunk and branch architecture coupled to a bifurcation architecture. Features such as tapered channel walls, curvatures and angles of channels, and zones of low fluid pressure can be used to reduce the size while maintaining wall shear rates within a narrow range. A hydraulic manifold can be coupled to a series of microfluidic layers to construct a compact microfluidic device.

A piping arrangement for a water purification apparatus that utilizes a number of manifolds and pipes to replicate the piping system of a water purification apparatus in a more compact manner. Metal pipes are joined to manifolds using elastomeric ring connections. Each manifold is designed with internal conduits that replicate the path of pipes in a water purification system.

A serial flow channel type filter cartridge includes a filter portion which includes a plurality of filter bodies and a plurality of filter housings corresponding to the plurality of filter bodies and independently accommodating the respective filter bodies and a cartridge header in which a top is formed in a structure in which a tap water pipe surrounds a perimeter of a purified water pipe, a plurality of filter accommodating pipes coupled with top ends of the plurality of filter housings which form the filter portion to seal an inside of the filter portion are formed at a bottom, and a serial structure type flow channel which allows tap water to sequentially flow into the plurality of filter accommodating pipes and then allows the water purified while sequentially passing through the plurality of filter bodies to be discharged through the purified water pipe is formed therein.

The present invention provides for a method for separating starch from processing solutions containing starch containing plants or roots such as potatoes, sweet potatoes, wheat, corn, tapioca, yams, cassaya, sago, rice, pea, broad bean, horse bean, sorghum, konjac, rye, buckwheat and barley to provide commercially acceptable starch while reducing disposal of solid or liquid waste matter into landfills or water treatment facilities.

The following disclosure related to gas-liquid separation in a two-phase flow. More specifically, the following disclosure relates to passive gas-liquid separation of a two-phase flow in an outlet manifold that combines an outlet flow from a plurality of electrolytic cells or an electrolytic cell stack where performance may be dependent on shape of a conduit conveying the two-phase flow.

A gas exchange system, said system comprising: a plurality of cartridges, each having a casing, said casing having a cartridge inlet adjacent to a first end and a cartridge outlet adjacent to an opposed second end; each casing having a bore in which is placed a gas permeable, liquid impermeable, hollow membrane; each hollow membrane having a membrane inlet arranged to receive a gas from an inlet chamber and a membrane outlet for venting said gas; each cartridge inlet in communication with a concentration zone, and arranged to receive a solvent from said concentration zone, so as to exit said solvent through said cartridge outlet; wherein said bore is arranged to flow said solvent adjacent to said hollow membrane so as to permit the exchange of gas through said gas permeable, liquid impermeable membrane.
