Applications

These vessels are engineered for use in a wide variety of water treatment contexts, such as:

✔ Sand and multimedia filtration systems
✔ Activated carbon filtration (for taste, odor & chlorine removal)
✔ Water softener resin tanks
✔ Reverse osmosis (RO) pre-treatment units
✔ Industrial water purification installations
✔ Commercial and municipal water projects

Their resistance to corrosion and chemical attack makes them suitable for aggressive water conditions and systems requiring high-pressure operation.
