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.

A microorganism sampling device includes: a head part that has a water supply channel to which a water supply pipe for supplying sample water can be connected; a housing part to an upper part of which the head part can be detachably attached; a frame-structured tube; a tubular filter that is arranged within the tubular body; a cup that communicates with the tubular filter and is attached to one end of the tube body; and a cap that has a channel communicating with the tubular filter and is attached to the other end of the tube body. The microorganism sampling device further includes a filter part housed in the housing part, in which a bottom part of the cup is supported by a bottom part of the housing part. The head part is attached to an upper part of the housing part.

A filtration device comprising a media basket, a baseplate, and a canister. The media basket is affixed to the baseplate. The canister has a cavity therein and is detachably coupled with the baseplate to enclose the media basket. The media basket contains a porous filtration material that efficiently removes contaminants from liquid. The device is configured to establish a first siphon to convey liquid from outside the device into the canister cavity through a canister pipe when a liquid level outside the filtration device is higher than the top of the weir in the canister pipe and configured to establish a second siphon to convey liquid from canister cavity through the top of a center riser pipe and out an outlet pipe when the first siphon has been established and the liquid level outside the filtration device is higher than the top of the center riser pipe.

A water purification device, with a first pressure cylinder, a second pressure cylinder, a first cylinder block and a second cylinder block. The first pressure cylinder, the second cylinder block and the second pressure cylinder are arranged successively, and the second cylinder block is arranged inside the first cylinder block. The first pressure cylinder and the second pressure cylinder both are open at one end and formed with a first through-hole at the other end, and enclosed. The first cylinder block and the second cylinder block both are open at two ends and arranged in a shape of hollow cylinder. A water inlet, which is communicated with flow passages formed between the first cylinder block and the second cylinder block, is formed on the second cylinder block, and a water outlet pipe communicated with the first cylinder block is inserted into an outer wall of the second cylinder block.

The invention relates to a water tank (1) with water filter cartridge (2), characterized in that the water filter cartridge (2) comprises two water filter cartridge outlets which are arranged concentrically to one another.

A method of installing a filter underdrain system includes: positioning a grout pad on a filter floor; positioning an underdrain block onto the grout pad such that the grout pad is displaced when the underdrain block is positioned on the grout pad; and inserting filler grout around the underdrain block.
