Partners engaged in water‑treatment projects frequently face this troublesome issue❓
During resin and filter media replacement, disassembly of valve heads and water distributors is required. The complex procedures may easily cause accidental damage to accessories, resulting in high time and cost consumption.
We hereby present our targeted solution: FRP composite tank series with loading‑unloading ports.
???? Core Advantages
???? Convenient loading and unloading, reduced accessory wear
Standard 4‑inch & 6‑inch flanged top‑loading / bottom‑unloading ports are provided.
Resin and filter media can be filled or discharged directly without dismantling valves and water distributors.
This significantly simplifies filling‑unloading processes and reduces damage risks for valves and water distributors, greatly lifting project O&M efficiency.

???? Integrated seamless tank opening, excellent anti‑seepage and pressure‑bearing performance
It is fitted with 6‑inch flanges at top and bottom ports, and a 4‑inch flange for top‑loading / bottom‑unloading port.
The tank opening and PE inner liner are integrally rotomolded with seamless connection, delivering more reliable anti‑seepage property and more stable pressure resistance.
The tank body is reinforced by epoxy resin and glass fiber winding, adopting proven classic craftsmanship for FRP tanks.

???? Food‑grade rotomolded PE inner liner, safe for drinking‑water applications
The inner liner is rotomolded from food‑grade PE raw material. It is non‑toxic, odor‑free and highly hygienic, suitable for drinking‑water treatment scenarios.

⚙️ Modified aviation‑aluminum flange port, handles complex working conditions
The 4‑inch and 6‑inch flange ports adopt modified aviation‑aluminum material.
It keeps stable pressure performance under various complex medium environments, effectively extending the overall service life of equipment.
???? Where can it be applied?
✅ Water softening equipment
✅ Ion‑exchange equipment
✅ Multi‑media filtration, activated‑carbon filtration
✅ Industrial pure‑water production, circulating‑water treatment, drinking‑water purification
On‑site for water‑treatment projects, durable tanks with easy later‑stage maintenance bring real cost reduction and efficiency improvement.
This FRP composite tank with loading‑unloading ports solves the pain points of filter‑media replacement for traditional tanks. Its integrated structure balances sealing performance and pressure resistance, providing a stable and reliable tank solution for water‑treatment systems.
