FRP Storage Tanks for Sewage, Manure & Wastewater Treatment

The Ultimate Solution for Corrosive Waste Containment

Leak-Proof. Acid-Resistant. Built for the Toughest Environments.

Handling toilet waste, raw sewage, and livestock manure requires more than just a container—it requires a barrier against corrosion. Traditional concrete tanks crack over time, and steel tanks rust rapidly when exposed to the ammonia and hydrogen sulfide gases found in organic waste.

Qingdao Chengda Huili New Materials Co., Ltd. engineers heavy-duty Fiberglass (FRP/GRP) Storage Tanks specifically designed for the harsh chemical environment of sewage and manure treatment. Whether for underground septic systems or above-ground chemical dosing, our filament-wound tanks ensure zero leaks and zero environmental contamination.

?️ Why FRP is Critical for Sewage & Manure?

Organic waste decomposition releases aggressive chemicals like Sulfuric Acid ($H_2SO_4$) and Ammonia. Our FRP tanks are chemically formulated to thrive where others fail.

• 100% Corrosion Immunity: Unlike concrete which suffers from "concrete cancer" due to sewer gases, our FRP material is inherently resistant to acids, alkalis, and salts.

• Leak-Free Environmental Protection: Manufactured as a single, seamless unit using filament winding technology. This eliminates the risk of groundwater contamination—a critical requirement for modern environmental regulations.

• Lightweight Installation: Weighing 1/10th of concrete, our tanks can be transported easily and installed in remote locations without massive cranes.

• High Structural Strength: Designed to withstand soil pressure (for buried tanks) and internal hydrostatic pressure.

⚙️ Product Specifications

We offer versatile configurations for both Toilet Waste (Septic) and Industrial Chemical Storage.

?️ Applications

Qingdao Chengda Huili tanks are currently serving in:

1. Municipal Sewage Treatment: Septic tanks for residential communities and public toilets.

2. Agriculture & Livestock: Storage and fermentation of manure from pig, dairy, and poultry farms (Biogas digesters).

3. Chemical Dosing: Storing acids/alkalis used in wastewater neutralization processes.

4. Collection Tanks: Holding tanks for toilet waste in mobile camps, construction sites, and RV parks.

Technical Insight: For underground applications, we reinforce the tank with stiffening ribs to handle the overburden load of soil and traffic, ensuring the tank never deforms.

? The Qingdao Chengda Huili Standard

• Seamless Winding: We use computer-controlled filament winding to create a tank with continuous strand integrity.

• Custom Fittings: We pre-install flanged nozzles exactly where your piping layout requires them, saving you installation time.

• Leak Testing: Every tank undergoes a hydrostatic water test before leaving our factory.
