Water Tank Anode (WST)

Water Tank Anode (WST)

CerAnode’s WST Horizontal Water Tank Anode system is engineered to provide reliable impressed-current cathodic protection (ICCP) for horizontal water storage tanks. Built using MMO mixed-metal-oxide coated titanium wire, the WST delivers consistent current distribution along the tank floor or walls. It’s designed for long-term service and minimal maintenance, helping extend the life of steel water tanks.

Key Features & Benefits

Materials & Construction:

• MMO-Coated Titanium Core: Uses a mixed-metal oxide coating to ensure long life, low consumption, and stable electrochemical behavior.
• Continuous Linear Anode: Flexible wire conforms to the tank’s geometry, allowing uniform current distribution.
• Environmentally Stable Design: Inert materials resist degradation in potable water, brackish, or fresh water environments.

Electrical & Performance:

• Optimized Current Distribution: The continuous layout provides even polarization, minimizing “hot spots” that can lead to localized corrosion.
• Power-Efficient: Low groundbed or backfill resistance improves overall ICCP system energy efficiency.
• Long Design Life: When properly designed, the MMO anode system can last for decades.

Durability & Environment:

• Corrosion Resistant: Suitable for continuous immersion and stable in water with varying chemistry.
• Robust Against Mechanical Stress: The titanium core resists deformation; the wire’s flexibility helps absorb installation stresses.
• Low Maintenance: Once installed, the system requires very little upkeep—mainly periodic cathodic (CP) system checks.

Installation & Flexibility:

• Pre-assembled Options: Can be delivered in spool or custom length to fit the exact tank dimensions.
• Customizable Specs: Design life, current output, wire diameter, insulation, and lead lengths can be specified to match project needs.
• Easy Integration: Compatible with CP test posts, rectifiers, and monitoring systems for seamless ICCP deployment.

Applications

• Steel horizontal water storage tanks, including potable water and fire-suppression tanks
• Above-ground water tanks with secondary containment liners
• New tanks or retrofits for existing tanks needing upgraded corrosion protection
• Tanks in remote or critical infrastructure where long-life CP protection is required
• Industrial water systems (e.g., process water, cooling water tanks)
