摘要： During the process of compressing air, atmospheric air along with water vapor and airborne contaminants are ingested into the air compressor. Many of these compressors utilize oil for lubrication, sealing and cooling. A compressor system utilizes drain valves to remove the condensate that accumulates in the system which are typically located on the compressor, moisture separators, coalescing filters, receivers, dryers, and drip legs. While the drain valves successfully remove the condensate, this condensate is now contaminated with lubricant. The compressor system also includes a filter for the removal of lubricant from the condensed water so that the water can be discharged to sewer. The filter is arranged to house a series of vertically stacked filter cartridges, each cartridge structured to pass fluid flow to the other cartridge. The housing is connected to the filter cartridges via a variable length pipe extension dependent on the number of filter cartridges used in an application.

摘要： There is disclosed a water treatment apparatus for treating stormwater, the water treatment apparatus comprising a volume of filter media, a baffle and an inlet conduit. The baffle extends upwards from the volume of filter media and defines a pre-treatment zone on one side of the baffle and a treatment zone on an opposing side of the baffle. The inlet conduit opens into the pre-treatment zone and is separated from the treatment zone by the baffle. The baffle is configured to regulate a flow of stormwater received via the inlet conduit by controlling the passage of stormwater from the pre-treatment zone to the treatment zone.

摘要： A filter system for filtering particles from a liquid includes an underdrain assembly having an underdrain defining at least one underdrain chamber and a media retainer assembly. The media retainer assembly includes an upper filter media retainer plate defining a plurality of hopper-shaped cavities and a lower filter media retainer plate defining a plurality of hopper-shaped cavities corresponding to the plurality of hopper-shaped cavities on the upper plate. The plates are in a nested arrangement such that the hopper-shaped cavities on the upper plate are in alignment with the corresponding plurality of hopper-shaped cavities on the lower plate to define a plurality of passages therebetween and allow for the passage of the liquid while preventing the passage of a filter media. During a backwash operation, the upper and lower plates are relatively moveable such that the backwash fluid releases any particles lodged in the passages between the plates.

摘要： The present invention has an object to provide a filtration apparatus and a filtration method which can treat a large quantity of flow in a short time and can sterilize raw water to a high level using only a physical treatment. The filtration apparatus and the filtration method according to the present invention includes a spring filter 2, a first precoat layer A of a filter aid 41 disposed on an upstream side thereof, and a second precoat layer B of a filter aid 42, and causes raw water to flow from a side of the second precoat layer B to carry out a filtration, and is characterized in that the filter aid 41 has a particle size distribution primarily including coarse particles which, due to a flow during a water transfer, aggregate at the openings to cover and form bridges over said openings with multiple pieces, whereas the filter aid 42 has a particle size distribution primarily including fine particles, which are smaller than the filter aid 41 and which themselves cannot form bridges over the openings, and in that the openings of the spring filter 2 and the particles of the second precoat layer B are adjusted in size by the first precoat layer A, which is held by the spring filter 2 due to bridging phenomenon.
