The FRP Water Treatment Tank 1365 is a premier solution for industrial water processing, featuring a diameter and height of φ325×1650mm, a 2.5” threaded top opening, and a design flow rate of 2.0～2.5 T/H. Its standout feature lies in exceptional anticorrosion properties, making it ideal for harsh water treatment environments.

Anticorrosion Characteristics

FRP water treatment tanks owe their superior corrosion resistance to a well-engineered structure, consisting of three layers: inner lining, structural layer, and outer protective layer. The inner lining has a high resin content (over 70%), with the inner surface resin-rich layer reaching approximately 95%. By selecting appropriate resins for the inner lining, the tank can resist different corrosive substances, adapting to various working conditions. For external corrosion protection, careful selection of resins for the outer layer ensures long-term durability.

Based on specific corrosive environments, different anticorrosive resins are used:

• Phthalic unsaturated polyester resin: Cost-effective for mild corrosion from acids, salts, or solvents.

• Vinyl ester resin, epoxy resin, or furan resin: Ideal for alkaline environments.

• Bisphenol A resin or furan resin: Suitable for acidic conditions.

• Furan resin: Excellent for solvent-based environments.

This versatility allows the tank to perform reliably in diverse corrosive settings.

Industrial Application Cases

• Municipal Wastewater Treatment Plant: A plant uses the 1365 tank to handle acidic wastewater with pH 2-3. The bisphenol A resin lining resists corrosion, ensuring continuous operation for 5+ years without leakage, reducing maintenance costs by 40% compared to stainless steel tanks.

• Industrial Effluent Treatment: A chemical factory employs this tank to process alkaline wastewater containing heavy metals. The vinyl ester resin lining prevents material degradation, meeting environmental discharge standards and extending service life by 30% vs. traditional tanks.
