BLUME WORLDWIDE SERVICES
Marine Growth Prevention System

Proven biofouling control since 1977

Blume Worldwide Services protects seawater intake, cooling and service-water systems from marine growth, corrosion and scale — for ships, offshore platforms and coastal facilities.

The Blume Antifouling System®

Three ways Blume protects your system

A single system addresses marine growth, corrosion and scale together, using controlled electrical current and sacrificial anodes rather than chemical injection.

Control marine growth

Copper ions inhibit the attachment and growth of marine organisms, including algae, mussels, barnacles and oysters.

Inhibit corrosion

Aluminum, and where appropriate iron anodes, help inhibit corrosion within seawater systems.

Reduce scale

The system helps reduce the tendency for scale to form on piping and equipment surfaces.

The System

A proven approach to seawater biofouling control

Marine growth, corrosion and scaling significantly affect the performance of seawater systems. Fouled piping, valves, strainers and heat exchangers restrict cooling-water flow, reduce heat-transfer efficiency, increase maintenance requirements and contribute to premature equipment replacement.

The Blume Antifouling System is designed to control these problems at their source, using impressed-current sacrificial anodes to introduce controlled amounts of copper and other beneficial ions directly into the seawater system.

ANODE MATERIAL 01

Copper

Marine growth control

Copper is the primary marine growth control agent in the Blume system. At very low concentrations, copper ions inhibit the attachment and growth of organisms such as algae, mussels, barnacles and oysters — and under the right conditions, can help cause established growth to detach.

ANODE MATERIAL 02

Aluminum

Corrosion and scale control

Released into seawater, aluminum forms aluminum hydroxide, which helps neutralize acidic conditions associated with corrosion. The resulting gelatinous compound also deposits on clean surfaces, helping reduce scale formation.

ANODE MATERIAL 03

Iron

Specialized corrosion protection

In applications involving copper-nickel alloys, additional ferrous ions can be beneficial. Where appropriate, Blume uses soft iron anodes for extra corrosion protection in systems such as copper-nickel condensers.

Engineered per installation

Designed around your system, not a shelf part

The number, size and location of anodes — and the electrical current applied — are determined by the requirements of each installation. No two seawater systems are exactly alike.

How It Works

Simple technology, controlled protection

The Blume Antifouling System combines anodes, electrical control and system monitoring into one coordinated installation.

Control panel

Precise voltage and amperage control, with independent ammeters for an immediate read on the condition of each anode.

  • Variable current control
  • Independent amperage monitoring
  • Circuit fault indication
  • Standard or explosion-proof configurations

Anodes

Supplied fully assembled to minimize installation work and help ensure reliable, long-term operation.

  • Copper, aluminum and optional iron
  • Large-diameter, coated construction
  • Controlled bottom-up wear
  • Inboard mounting, solid bolt design

Monitoring & protection

Anode wear monitoring is built into both the anodes and the control system, not added on afterward.

  • Circuit continuity testing
  • Visual replacement indication
  • Optional remote alarm contacts
  • Automatic power shutoff when needed

Controlled wear design prevents the hour-glassing and potential break-off associated with uneven anode wear — and every unit is manufactured in the United States.

Why BAS

Marine growth isn't just an inconvenience

Unchecked fouling restricts water flow, reduces cooling efficiency, accelerates corrosion, and drives up maintenance and equipment-replacement costs. Blume combines growth control with corrosion- and scale-inhibiting technology in a single system.

Comparison of a biofouled, corroded pipe versus a clean pipe protected by the Blume system

No chemical injection

No chemicals to handle, store or keep in inventory — the system works through controlled current and anode chemistry alone.

Corrosion-inhibiting chemistry

Unlike improperly controlled chlorine-based systems, which can accelerate corrosion, Blume pairs copper-ion antifouling with aluminum and, where appropriate, iron.

Lower capital & operating cost

Typically lower acquisition and operating costs than sodium hypochlorite generation, plus reduced cleaning, spare parts and downtime.

Proven technology

Developing marine growth control technology since 1977, across a broad range of marine, offshore and coastal installations.

Designed for reliability

Controlled anode wear, independent current monitoring and optional remote alarms — engineered with real-world operation in mind.

Made in the USA

Manufactured in the United States, with close control over quality, construction and long-term product reliability.
