The present invention provides: an artificial soil composition comprising 100 parts by weight of nonwoven fabric, 90-110 parts by weight of urethane foam, 90-110 parts by weight of a low-melting-point bonding yarn, 5-10 parts by weight of an absorbent polymer, 0.3-1 parts by weight of a charcoal powder, and 0.3-1 parts by weight of a zeolite powder; and a method for manufacturing an artificial flowerpot by using the same.
The present invention relates to a method for manufacturing an asymmetric polyvinlylidenefluoride (PVDF) hollow fiber membrane, which enables effective mixing of PVDF and a diluent without using separate inorganic fine powder, such as silica; in which a PVDF hollow fiber membrane is manufactured using a thermally induced phase separation method having an advantage of allowing easy obtaining of a separation membrane of consistent quality due to a key factor in controlling the phase separation in the two-substance mixture system of the polymer and the diluent being temperature, which is a manufacturing variable that is relatively simple and easy to control; in which a technique is applied for producing a temperature difference between the outer and the inner surfaces of a PVDF hollow fiber, and therefore, finally an asymmetric structure is expressed in which the inner surface side and the outer surface side of the PVDF hollow fiber have mutually different pore sizes and distributions; and which, even when an extraction process and a drawing process are applied, achieves a higher tensile strength and a larger average pore size, and thus higher porosity and water permeability than conventional hollow fiber membranes, since inorganic fine powder is not included.
The present invention relates to the structure of a pressurized hollow fiber separation membrane module, and a method for washing the same. In particular, a central baffle of a cylindrical shape having a hollow is installed inside the pressurized hollow fiber separation membrane module, wherein the central baffle comprises: an air zone including, on the outer periphery thereof, at least one back washing hole which is regularly or irregularly formed in a penetrating manner; and a water zone including at least one back washing hole which is regularly or irregularly formed in a penetrating manner. The central baffle is installed in the center of the pressurized hollow fiber separation membrane module on the same axis as a concentration part so as to allow concentrated water and cleaning air to uniformly flow in all directions of a housing and to improve an increase of the pressure and linear velocity or a stagnating phenomenon, or the like, which may occur in the conventional modules, thereby increasing the effect of physical washing and decreasing contamination of the separation membrane.

Disclosed is a cartridge module of hollow fiber membranes, which can be easily mounted on and dismounted from a module mounting frame, and allow a process for removal of the inter-membrane clogging to be performed in an effective and simple manner. The cartridge module is mainly characterized in that a water collecting header has an opened first collected water outlet, which is located at the upper portion of the front surface of the water collecting header and can be opened and closed; and a closed second collected water outlet, which is located at the lower portion of the front surface of the water collecting header and can be opened and closed. The inter-membrane clogging can be very simply removed by dismounting, turning upside down, and remounting the cartridge module.
