An object of the present invention is to provide a separation membrane module in which an end member is prevented from coming out even at the occurrence of a reverse pressure or the like. The invention relates to a separation membrane module which is equipped with a cylinder-shaped housing and a tubular separation membrane and which takes out a fluid which has permeated the tubular separation membrane. An end pipe is connected to one end portion of the tubular separation membrane; the end pipe is supported by a support plate which is disposed so as to traverse the housing; and an end plug is connected to the other end portion of the tubular separation membrane. The separation membrane module is further equipped with a coming-out preventive member.

A membrane filtration system and a membrane bio reactor including the same are described. In an example, the membrane filtration system includes: a treatment tank; a membrane support frame disposed in the treatment tank and mounted with a separation membrane; a separation membrane module mounted on the membrane support frame; a vane member disposed at a lower end of the membrane support frame and provided to lift sludge accumulated at a lower part of the treatment tank; and a reciprocating portion connected to the membrane support frame and reciprocating the membrane support frame, in which the separation membrane module includes an upper frame and a lower frame and a hollow fiber membrane installed between the upper frame and the lower frame.

Described is a method for concentration and extraction of gas field chemicals. The method includes collecting produced water from a gas oil separation plant, treating the produced water to remove oil, and receiving a feed solution containing a gas field chemical and water. The treated produced water is used as a draw solution to concentrate and absorb water from the feed solution using a forward osmosis chamber. A concentrated feed solution containing the gas field chemical and a diluted draw solution is produced. The concentrated feed solution is extracted and stored for injection into gas wells.

This invention relates generally to a filtration process and apparatus for separating valuable or harmful process liquids from mixtures or slurries that contain such liquids and solid particles. In particular, the invention relates to a filtration process for separating Process Liquid from a feed slurry that comprises a mixture of the Process Liquid and solid particles, the process employing a Sweep Liquid that is less dense than the Process Liquid.

An extracorporeal system for lung assist includes a system housing, which includes a blood flow inlet and a blood flow outlet and a fiber bundle housing movably positioned within the system housing. The fiber bundle housing includes a gas inlet and a gas outlet. A fiber bundle is in operative connection with the fiber bundle housing. The fiber bundle includes a plurality of hollow gas permeable fibers, wherein lumens of the plurality of hollow gas fibers are in fluid connection with the gas inlet at a first end thereof and in fluid connection with the gas outlet as a second end thereof. The system further includes an actuator to impart oscillatory motion to the fiber bundle housing and thereby to the fiber bundle.

Disclosed is a membrane bioreactor system capable of minimizing the energy consumption while guaranteeing excellent membrane cleaning effect. According to the membrane bioreactor system of the present invention, a filtration apparatus for solid-liquid separation is provided in an aerobic tank and a portion of fine bubbles supplied to increase the dissolved oxygen of wastewater introduced into the aerobic tank are used for cleaning the membrane of the filtration apparatus.

A method of obtaining a compound may include adding a substrate to a medium in a reactor, and reacting the substrate in the reactor to form the compound. A first stream is separated from the reaction liquid through a first membrane. A second stream is separated from the reaction liquid through a second membrane. The first membrane is a filtration membrane and the second membrane is configured for liquid-gas or liquid-liquid extraction The first membrane and the second membrane are at least partially immersed in the medium and are moved relative to the reactor during the separation steps.

The present disclosure relates to an apparatus and an apparatus assembly for assessing the suitability of a membrane, such as an osmotic membrane in an osmotic process. Furthermore, the apparatus, and apparatus assembly provide the means to optimise the parameters of an osmotic process, including the ability to gather key data for different membrane based osmotic systems to enable osmotic process and system optimisation.
