Seawater desalination FRP tank, a core representative of structural composite vessels, is an ideal choice for commercial and industrial water treatment and storage. Made of non-corrosive materials, it combines cost-effectiveness and durability, stably performing in complex working conditions and providing reliable container support for seawater desalination, industrial wastewater treatment and other scenarios.

Core Parameters & Structural Advantages

This seawater desalination FRP tank has an imperial size of 4087, with a tank diameter and height of φ1000×2200mm. It adopts a Top&Bottom Opening 4” Thread design, facilitating installation, maintenance and medium replacement. The Design Flow Rate is stable at 17.0～23.0T/H, adapting to the continuous operation needs of medium and large industrial water treatment systems.

Product Features & Material Analysis

The 100% composite fiberglass structure of the seawater desalination FRP tank is its core competitiveness:

• Excellent performance in harsh chemical environments, resistant to acids, alkalis and corrosion, and able to withstand long-term erosion of high-salinity seawater and complex components of industrial wastewater;

• Absolutely rust-free, fundamentally solving the problem of easy corrosion and short service life of traditional metal containers;

• Almost no maintenance required, significantly reducing later operating costs;

• Flexible capacity, up to 2500 gallons, and customizable to accurately match water treatment and storage needs of different scales;

• Equipped with a factory-supported 5-year warranty, ensuring better quality.

Its building material is made of high-strength fiberglass as the base material, combined with special resin, which has both the high strength of fiberglass and the corrosion resistance of resin, ensuring the structural stability of the tank under harsh conditions such as high pressure and high salt.

Industrial Application Case

A seawater desalination project of an island resort once faced the problem of container corrosion: traditional metal tanks leaked after only 8 months of use in the high-salt seawater environment, with high maintenance costs. After introducing the seawater desalination FRP tank, relying on the corrosion resistance of its composite fiberglass structure, the equipment operated continuously for 3 years without rust or leakage. Cooperating with the reverse osmosis system, the tank processes 200 tons of seawater per day, and the produced water meets the domestic water needs of 500 tourists and employees in the resort. Due to no need for frequent container replacement, the project saves 120,000 yuan in annual maintenance costs, the comprehensive service life of the equipment is extended to more than 15 years, and the return on investment is increased by 40%.
