The present invention provides a water purifier which is easily removable from a drinking water supply apparatus, and has a built-in filtration filter with high efficiency of purifying raw water of a bottle. The water purifier is removable from a drinking water supply apparatus, and the drinking water supply apparatus including a bottle for containing water and a main body which has a recess into which a neck of the bottle is insertable. The water purifier is characterized by being placed between the recess of the main body and the neck of the bottle.

Water purifier

In a combination including a pitcher-type water purifier and its purification cartridge, which can adsorb and eliminate chemical substances such as chlorine from raw water, eliminate bacteria, and prevent propagation of bacteria and provide safe purified water in a short period of time, even when the purified water has been stored for a long-period time, the pitcher type water purifier contains a casing divided into upper and lower parts as a raw water reservoir portion and a purified water reservoir portion, and has a purified water pouring opening in the purified water reservoir portion; and the purification cartridge has a raw water inlet in an upper face thereof and a purified water outlet in a bottom face, and adsorbent is filled in an upper layer of an interior thereof and hollow fiber membranes are filled in a lower layer thereof at an opening rate &#x3c3; of 25-58%.

Pitcher type water purifier and purification cartridge for the water purifier

A catchment header allowing a plurality of membrane modules to be connected thereto, having a tubular catchment part with a Young's modulus of 4.0 GPa or less for collecting and taking out filtrated liquid from the membrane modules, wherein at least a part of the tubular catchment part is covered with a reinforcement member with a Young's modulus of 4.0 to 250 GPa, the tubular catchment part of the catchment header is preferably formed of a synthetic resin, and the cross sectional area thereof perpendicular to the longitudinal direction of the tubular catchment part is preferably 4 to 36 cm.

A crude oil processing method is provided wherein a membrane module is immersed in the crude oil contained in a processing tank and the crude oil is pressurized or driven by gravity for gravitational filtration, thereby to pass through the membrane, with the dehydrated oil that has passed being taken out through an oil collecting pipe. According to this method, a high degree of separation and removal of water content from the crude oil can be carried out regardless of the properties of the crude oil, and muddy matter can also be separated and removed.

Device and method for processing crude oil

A water purifier includes a diverter which can be detachably attached to a water faucet to select a plurality of water passages and a filter cartridge which can be detachably attached to the diverter to purify a water to be supplied through the diverter. The diverter is provided with a connector portion including a projection having a pair of guide grooves. The filter cartridge is provided with an engaging portion which can be inserted and fitted in the guide grooves. Disclosure is also directed to a diverter which includes a substantially cylindrical body which defines therein a main water passage to be connected to the faucet, and a rotatable selecting member which can be coaxially and rotatably fitted on the substantially cylindrical body and which is provided with a plurality of branch water passages which can be selectively registered with the main water passage of the substantially cylindrical body in accordance with the rotation of the selecting member.
