Nordstone | Sand Filter Pressure Vessel

Sand Filter Pressure Vessel – Advanced Industrial Filtration Solutions

Sand Filter Pressure Vessels are specialized pressure vessels designed for high-efficiency filtration of suspended solids and impurities from liquids. They are widely used in industrial water treatment, chemical processing, petrochemical plants, and environmental engineering to ensure clean water, process efficiency, and equipment protection.

At NORDSTONE, we design and manufacture sand filter vessels with robust mechanical construction, optimized flow design, and compliance with international standards, including ASME Section VIII Div.1, API, and PED.

What is a Sand Filter Pressure Vessel?

A sand filter pressure vessel removes particulate matter from liquid streams using a sand or granular media bed. Liquid enters the vessel and passes through the sand media, which traps suspended solids, while clean filtered water exits from the bottom or side outlet.

Key components include:

•

Vertical or horizontal cylindrical shell

•

Top distributor and under-drain system for even flow

•

Sand or multimedia filtration bed

•

Inlet and outlet nozzles

•

Air release and drain systems

•

Manways for inspection and maintenance

These vessels ensure efficient filtration, minimal pressure drop, and extended media life, making them ideal for continuous operation.
