INDUSTRIAL COOLING SYSTEMS

Cooling water treatment chemicals for scale, corrosion and biofouling control

Chemistry and monitoring across recirculating industrial cooling systems.

Overview

INDION cooling-water treatment programmes combine selected chemicals and monitoring to control corrosion, scale, fouling and biological growth in industrial cooling systems. The chemistry is chosen for the makeup water, system materials, heat load, cycles of concentration and operating conditions.

Applications

  • Cooling towers

    Chemical treatment and monitoring for recirculating cooling water.

  • Industrial cooling-water circuits

    Control objectives selected for water quality, materials and heat load.

  • Automated dosing

    INDION Autochem supports selected cooling-tower monitoring and dosing functions.

Process use and chemical role

Chemistry in the cooling-water circuit

Process stage or systemChemical or operational role
Corrosion and scale controlCorrosion inhibitors and scale inhibitors protect system surfaces and help limit mineral deposition.
Dispersants and silica controlPolymeric dispersants and silica inhibitors are selected where the makeup water and operating concentration create a fouling or silica risk.
Microbiological controlOxidizing or non-oxidizing biocides and biodispersants are selected for the system’s biological-control requirements.
Monitoring and feed controlWater chemistry, corrosion, deposits and biological activity can be monitored. INDION Autochem can automate selected cooling-tower measurements, dosing functions and timers, depending on model.

Where the chemicals are applied

Treatment chemicals are fed into the cooling-water circuit at locations and rates selected for the plant design and treatment programme. The exact feed point, control limits and biocide schedule should be confirmed for the system rather than copied from a generic page.

Selection and implementation

SYSTEM-SPECIFIC SELECTION

Select chemistry for makeup-water analysis, system materials, heat load, cycles of concentration, operating conditions and biological-control requirements. Confirm feed points, control limits and biocide schedules for the plant.

Scaling colours follow the approximate LSI: an undersaturation indication below 0, green from 0 to 0.75, amber above 0.75 up to 1.5, red above 1.5. Negative LSI is shown separately rather than as green, because it may indicate a tendency to dissolve calcium carbonate. These classifications remain indicative, as LSI alone does not determine actual scale deposition.

The silica screening reference is reported separately above. Corrosion needs metallurgy-specific technical review; microbial control requires monitoring. No measured corrosion rate, biological count or approved maximum CoC is calculated.

Recommended treatment categories

  • Scale inhibitor

    Recommended for control of mineral deposition. Selection depends on circulating chemistry and limiting salts.

  • Corrosion inhibitor

    Recommended following review of metallurgy, water chemistry, oxidant exposure and operating conditions.

  • Biocide treatment

    Consider oxidising biocide for routine control and non-oxidising biocide as a supplemental or periodic option, subject to site review.

No specific products, doses or guaranteed cycles are automatically prescribed. The technical team will review these.

FAQs

What does a cooling-water programme control?

The programme may address corrosion, scale, silica, fouling and microbial growth.

Can treatment support higher cycles of concentration?

A programme can be designed around the required operating concentration and water quality; the achievable cycles depend on the full system and its limits.

Can the dosing be automated?

INDION Autochem supports selected cooling-tower monitoring and dosing-control functions. Model configuration determines available controls.
