Product description
Industrial pressure vessels are used in water treatment systems to contain filtration or ion exchange media such as resins, activated carbon, or specialty treatment materials. These vessels provide a durable housing for media beds used in softening, deionization, dechlorination, and other purification processes. Constructed from reinforced composite materials with a high-density polyethylene liner, the vessels are designed for continuous operation in commercial and industrial water treatment installations.Technical overview
Pressure vessels are cylindrical tanks designed to hold water treatment media while allowing water to flow through the media bed for filtration or chemical exchange processes. The vessel includes a threaded neck connection that allows installation of a head assembly, riser tube, and distribution screens. Water enters the vessel, flows through the media bed where treatment occurs, and exits through the outlet connection. These vessels are compatible with a range of distribution heads and control valves used in filtration and ion exchange systems.Operating principle
Water enters the pressure vessel through an inlet connection installed in the vessel head. The water flows downward through the media bed where treatment occurs. Depending on the installed media, the vessel may perform filtration, adsorption, or ion exchange. Treated water is collected through the lower distribution system and exits through the outlet connection. During regeneration or backwashing cycles, the flow direction can be reversed to clean the media bed or restore ion exchange capacity.Material options
Typical materials of construction include:- Fibreglass reinforced composite outer shell
- High density polyethylene (HDPE) internal liner
- HDPE neck insert thread
- Polymeric distribution components
- Elastomer sealing elements
Available micron ratings
Pressure vessels themselves do not determine filtration micron rating. Filtration performance is determined by the treatment media installed inside the vessel, which may include:- Ion exchange resins
- Activated carbon media
- Granular filtration media
- Specialty adsorption media
