FRP Softener Vessel

 

🔹 The FRP Softener Vessel is a high-performance pressure filtration tank designed for industrial and municipal water treatment systems.
Made from fiberglass-reinforced plastic (FRP) and food-grade PE liner, it replaces traditional steel vessels with superior corrosion resistance, light weight, and extended service life.

As an essential component of RO pretreatment, ion exchange, and media filtration systems, this vessel removes:

• Suspended solids
• Turbidity
• Iron and manganese
• Chlorine and organic contaminants

Compatible with diverse filter media such as quartz sand, activated carbon, anthracite, or manganese greensand, it ensures consistent water clarity with inlet turbidity ≤20 NTU and outlet ≤3 NTU.

Built for reliability, the FRP Softener Vessel withstands 150 psi working pressure and temperature up to 50°C, performing flawlessly even in high-salinity or high-chloride environments.

✅ Xi'an Ink-blue Environmental Protection Technology Co., Ltd. provides a full range of FRP storage tanks and corresponding accessories for all models. We help you assemble a complete FRP filtration system in one stop.

Universal FRP Tanks Structure:

Universal FRP tanks are generally composed of an upper opening, a lower opening (except for 2.5" and part of 4"), tank body and a base.

• PPO material, thread connection (2.5" and 4")
• Aviation aluminum, flange connection (6")

👉 Base:

• Standard base: reinforced plastic (tank size: 6"–16");
• Round base: reinforced plastic (tank size: 18"–21");
• Tripod base: FRP (tank size: 24"–80")

 

 

 

✅ Corrosion-Resistant Construction – Non-metallic FRP eliminates rust, oxidation, and corrosion issues.
✅ High Durability – Over 150,000 tested cycles ensure long service life under high pressure.
✅ Lightweight & Easy Installation – 1/4 the weight of steel tanks, lowering logistics and labor costs.
✅ Cost-Efficient Operation – Compatible with automatic backwash valves to reduce manual intervention.
✅ Modular & Scalable – Suitable for single-tank, twin-tank, or multi-media configurations.
✅ Environmental Compliance – Non-toxic materials, recyclable FRP, compliant with NSF/CE/ISO standards.

 

 

 

• RO Pretreatment Systems – Remove suspended solids before reverse osmosis.
• Industrial Water Softening – Protects boilers, chillers, and cooling towers.
• Municipal Water Supply – Improves water clarity and reduces iron content.
• Food & Beverage Production – Ensures hygienic filtration for ingredient water.
• Agricultural Irrigation – Reduces sediment and hardness for crop protection.

 

 

 

The FRP vessel operates under pressure:

1. Raw water enters through the top distributor.
2. Water passes downward through selected filtration media.
3. Contaminants are trapped, and clear water exits via the lower collector.
4. Periodic backwashing regenerates the media and maintains flow efficiency.

Its smooth interior prevents media loss and scaling, while its seamless structure ensures zero leakage even in long-term operation.
