A water catchment and lawn edging system includes a cap, a channeled drain fixture, and at least one base clip. The base clip, which connects the system to the ground surface, is connected to a bottom end of the channeled drain fixture. Depending upon the length or the profile of the channeled drain fixture, the system can utilize a single base clip or a plurality of base clips to properly support the system. The cap is continuously connected along the channeled drain fixture from a top end of the channeled drain fixture. The cap may include a plurality of drain openings to provide additional drainage for the system. Collectively, the cap, the channeled drain fixture, and the base clip function as a water catchment and lawn edging system so that surface and ground water can be drained and filtered away from a collecting area and discharged into an outfall.

A receiver dryer includes a first body and a second body, one end of the second body away from the first body defining first and second connecting ports. The receiver dryer includes a filter cartridge including a first mating portion, a second mating portion, and a filter part at a middle portion; the first mating portion fits with an inner wall of the second body, one space allowing refrigerant to flow is formed between the filter part and the inner wall of the second body, the second mating portion is connected to the second connecting port, the space between the filter part and the inner wall of the second body communicates with the first connecting port, an inside of the filter part communicates with the second connecting port via the second mating portion, and refrigerant is filtered at least once when flowing between the first and second connecting ports.

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.

A support grid assembly for use in a vessel. The support grid assembly includes panels each including a first wall including a media-supporting screen and a second wall to be supported by the vessel wall inner surface. A manifold is coupled to the panels and is in hydraulic communication with vessel outlet. The manifold and the panels permit fluid to flow through the screen in each panel, through the panels, into the manifold, and through the manifold to the outlet of the vessel, as well as in the reverse direction. At least a portion of the first wall may slope downward toward the manifold, and at least a portion of the second wall may form a bottom surface that is curved to substantially conform to a curvature of the vessel wall inner surface. The panels may be arranged in a circular configuration extending radially from the manifold.

A system for treating water for use in aquatics or recreational facilities is disclosed. The system includes a media filter vessel, a pressure sensor, and a monochromatic light source. A method of treating water for use in aquatics or recreational facilities is also disclosed. The method includes fluidly connecting a media filter vessel to a source of water for use in aquatics or recreational facilities, illuminating a media inside the media filter vessel, observing a monochromatic light source display a first indicator and observing a monochromatic light source display a second indicator. A method of retrofitting a media filter vessel is also disclosed. The method includes installing a pressure sensor on the media filter vessel, installing a monochromatic light source and operably connecting the monochromatic light source to a manual control and to the pressure sensor.

Process vessels can contain one or more entry zones containing stability-improving materials. The entry zones address bed movement and filtration problems. The stability-improving material can be positioned above a treating zone or above a processing bed within the vessel. Entry Zones are intended to improve the stability of downstream operations.
