Seawater Desalination Water Storage Tank

Saline Water Treatment Tank

The salt water treatment storage tank is a special type of tank specifically designed for industrial high-salt wastewater, soft water systems, or seawater desalination processes. Due to the extremely corrosive nature of salt water, this tank is usually lined with high-grade stainless steel or carbon steel with anti-corrosion coatings, which can effectively resist the erosion of chloride ions.

• Heavy-Duty Carbon Steel Shell: A robust cylindrical body engineered with high-strength structural steel, treated with marine-grade anti-corrosive coatings to withstand harsh saline environments.

• Reinforced Torispherical End-Caps: Heavy-gauge, hydraulically formed hemispherical ends precision-welded to ensure uniform pressure distribution and long-term structural integrity.

• Integrated Top Manhole: A reinforced, bolted access port located on the upper shell for easy internal inspection, maintenance, and liner replacement.

• Heavy-Duty Lifting Lugs: Multiple strategically welded hoisting points designed for balanced lifting and safe crane maneuvering during site installation.

• High-Stability Saddle Supports: Precision-fabricated steel saddle brackets welded to the base, ensuring stable weight distribution on concrete foundations.

• Process Nozzle Array: Strategically positioned inlet, outlet, and drain flanged ports for seamless connection to high-volume desalination piping systems.

Product Advantages

Durable heavy industrial seawater desalination water storage tanks, featuring excellent corrosion resistance, high pressure-bearing capacity, and leak-proof performance, can be customized in terms of size and structure to meet the requirements of large-scale water treatment projects.

• Exceptional Corrosion Resistance: Engineered with specialized internal coatings or rubber linings to resist high chloride concentrations, preventing rust and chemical degradation.

• Optimized Hydraulic Design: The horizontal configuration provides a lower center of gravity and high volume stability, making it ideal for high-capacity industrial fluid management.

• Long-Term Structural Durability: Built using automated welding techniques and high-tensile steel, ensuring the tank withstands constant hydrostatic and operational pressure.

• Maximum Safety Compliance: Every tank undergoes 100% non-destructive testing (NDT) and rigorous hydrostatic testing to guarantee zero-leakage performance under harsh marine conditions.

• Low Maintenance Operation: The smooth, premium internal protective layer minimizes biofouling and scale buildup, significantly extending the service interval.

Customized heavy-duty carbon steel brine storage tank Material

This horizontal seawater storage tank is mainly made of stainless steel or carbon steel with a special heavy-duty anti-corrosion inner lining. It is suitable for seawater with high chloride ion corrosion conditions. The exterior is covered with an insulation protection layer, which can achieve heat insulation and cold preservation, resist external environmental erosion, have a stable structure and strong sealing performance. It is widely used for the safe storage of seawater media in scenarios such as seawater desalination and marine engineering.

Material & Specifications

Technical Parameters

• Working Temperature Range: -10°C to 60°C (optimized for industrial seawater and brine treatment).

• Design Pressure: Atmospheric to 1.6 MPa (Standard and pressurized variants available).

• Internal Lining Options: Epoxy phenolic coating, Polyurethane coating, or vulcanized rubber lining.

Application Scenarios

The seawater treatment water tank is specially developed for high-salt and highly corrosive marine conditions. It is widely applicable to small and medium-sized seawater desalination projects and coastal water purification renovation projects. It can achieve storage of raw seawater, pre-treatment buffering, stable pressure storage of produced water, and temporary storage of tail water. It effectively matches the entire seawater treatment process flow, ensuring the continuous and stable operation of the system.

• Seawater Desalination Plants: Serving as robust storage and buffer vessels for raw seawater, concentrated brine, or treated permeate water.

• Marine & Offshore Platforms: High-reliability fresh water and process water storage on oil rigs and large marine vessels.

• Coastal Industrial Power Plants: Large-scale water holding units for cooling towers and boiler feed water systems near coastal areas.

• Municipal Water Treatment: Serving as a primary reservoir in regional water purification and reverse osmosis (RO) systems.

• Chemical & Petrochemical Refining: Holding tanks for aggressive process fluids, saline solutions, and industrial wastewater treatment.

Desalination Water Storage Tank Packing & Delivery

The seawater desalination water storage tank is packaged in standardized export format. The main components are treated with anti-rust and waterproof coating, while the scattered parts are classified, encapsulated, and fixed for reinforcement. The packaging structure is suitable for container loading and ocean transportation, effectively resisting road vibrations and water vapor erosion, ensuring that the appearance and performance of the product are not affected upon arrival at the destination.
