Pre-Treatment Tanks (FRP Vessels): The three large vertical fiberglass-reinforced plastic (FRP) tanks typically handle multi-stage media filtration (such as sand, activated carbon, and water softening/resin) to remove sediment, chlorine, taste, odor, and hardness before water reaches the membranes.
High-Pressure Pump: A vertical multistage centrifugal pump provides the necessary pressure to push water through the semi-permeable reverse osmosis membranes.
Purification Capacity: Industrial and commercial units of this size typically range from 1,500 GPD (Gallons Per Day) up to several thousand gallons per day (or 500–1000+ liters per hour) depending on the exact configuration.
