Types of Cortec® Water Treatment Products

Boiler and Condensate Treatment

Boiler and condensate products help control corrosion associated with dissolved oxygen, carbon dioxide, acidic condensate, and changing operating conditions. Product selection depends on boiler pressure, temperature, feedwater quality, system design, metallurgy, and existing treatment chemistry.

Cooling-Water Treatment

Cooling-water products help manage corrosion, mineral scale, suspended deposits, and system cleanliness in open or closed cooling systems. Treatment programs should be matched to the makeup water, cycles of concentration, system metallurgy, and operating temperature.

Closed-Loop Corrosion Inhibitors

Closed-loop treatments protect compatible steel, copper, brass, aluminum, galvanized steel, and other metals in heating, cooling, and glycol systems. Correct concentration and periodic monitoring are necessary to maintain protection.

Antiscalants

Antiscalants help prevent dissolved minerals from forming deposits on heat-transfer surfaces, piping, pumps, and other water-contacted components.

Dispersants and Deposit-Control Products

Dispersants help keep suspended material and organic deposits from attaching to system surfaces. Certain dispersants may be used with compatible biocide programs but are not themselves biocides.

Hydrostatic Testing Additives

Hydrotest additives help protect internal metal surfaces during pressure testing and may reduce flash corrosion after equipment is drained.

Wet and Dry Layup Products

Layup products protect boilers, heat exchangers, cooling systems, tanks, piping, and process equipment while they are offline. Treatment may involve maintaining a treated liquid or applying a dry Vapor phase Corrosion Inhibitor inside an enclosed system.

Specialty Water Treatment Additives

Specialty products are available for low-pH water, saltwater, brine, ballast tanks, fire-water systems, and other applications with unusual chemistry or operating conditions.

Boiler and Condensate Corrosion Control

Boiler systems may experience corrosion in the feedwater, steam, condensate, and idle sections of the system. Dissolved oxygen can attack boiler metal, while carbon dioxide may form acidic condensate that damages return lines.

A complete boiler treatment program may include:

• Feedwater conditioning
• Oxygen scavenging
• pH and alkalinity control
• Scale and deposit control
• Steam and condensate-line protection
• Blowdown management
• Wet or dry layup protection

Boiler treatment should be designed and monitored by qualified personnel familiar with the boiler pressure, metallurgy, operating requirements, water chemistry, and applicable regulations.

Cooling-Tower and Open-Loop Treatment

Cooling towers continuously introduce air and concentrate dissolved minerals through evaporation. These conditions can increase corrosion, scaling, fouling, and biological growth.

A cooling-water program may require:

• Corrosion inhibitors
• Antiscalants
• Dispersants
• Compatible oxidizing or non-oxidizing biocides
• pH control
• Conductivity and blowdown control
• Makeup-water treatment
• Routine chemical and microbiological testing

Corrosion inhibitors and dispersants should not be assumed to replace a properly designed biological-control program.

Closed-Loop Water Treatment

Closed loops lose less water than open systems but can still experience corrosion from oxygen intrusion, poor initial water quality, glycol degradation, mixed metals, leaks, and insufficient inhibitor concentration.

Treatment should account for:

• Carbon steel, copper, brass, aluminum, and galvanized components
• Freshwater or glycol concentration
• Operating temperature
• Makeup-water frequency
• System leaks and oxygen entry
• Existing inhibitor chemistry
• Elastomer, seal, and pump compatibility

Controlling Scale and Deposits

Scale forms when dissolved minerals precipitate and attach to system surfaces. Even a thin mineral layer can interfere with heat transfer, restrict flow, increase energy use, and create areas where localized corrosion develops.

Antiscalant selection depends on the specific minerals present, saturation levels, pH, temperature, cycles of concentration, residence time, and compatibility with the rest of the treatment program.

Hydrostatic Testing and Post-Test Preservation

Hydrostatic testing introduces water into new or existing tanks, vessels, pipelines, heat exchangers, and other equipment. Corrosion may occur during testing or after draining when water remains in low points, crevices, and dead legs.

A hydrotest preservation plan should consider:

• Test-water chemistry and chloride content
• System metallurgy
• Test duration
• Required inhibitor concentration
• Drainage and drying capabilities
• Wastewater discharge requirements
• Time between testing and commissioning
• Need for wet or dry post-test preservation

Wet vs. Dry Equipment Layup

Wet Layup

During wet layup, the system remains filled with appropriately treated water. Inhibitor concentration, water chemistry, circulation, oxygen entry, and microbial activity may require periodic monitoring.

Dry Layup

During dry layup, equipment is drained and dried before a powder, emitter, fogging treatment, or other Vapor phase Corrosion Inhibitor is introduced. The equipment should then be closed or sealed to retain the protective vapor concentration.

Choosing a Layup Method

The best method depends on the system design, shutdown duration, ability to drain and dry the equipment, climate, accessibility, startup schedule, and required inspection frequency.

Water Analysis and Product Selection

Effective treatment starts with understanding the system and its water chemistry. Important factors include:

• pH and alkalinity
• Total hardness
• Chlorides and sulfates
• Conductivity and total dissolved solids
• Dissolved oxygen
• Iron and copper levels
• Silica and other scale-forming minerals
• Glycol type and concentration
• Temperature and pressure
• Flow and circulation rate
• System metallurgy
• Existing treatment chemicals
• Microbiological conditions

Dosing and Chemical Feed

Depending on the product and system, water-treatment chemicals may be introduced through:

• Metering pumps
• Pot feeders
• Day tanks and chemical-feed tanks
• Batch addition
• Makeup-water lines
• Feedwater or condensate lines
• Deaerator storage sections
• Dissolving or controlled-release devices

Feed location, dosage, dilution, mixing, and injection rate should follow the current technical data sheet and the approved treatment program.

Monitoring a Water Treatment Program

Water treatment requires ongoing monitoring rather than a one-time chemical addition. A program may include:

• Inhibitor concentration testing
• pH, conductivity, and hardness testing
• Chloride and alkalinity testing
• Corrosion coupons or probes
• Iron and copper trend analysis
• Scale and deposit inspections
• Microbiological testing
• Blowdown and makeup-water records
• Leak and fluid-loss monitoring
• Regular equipment inspection

Safety, Compliance, and Professional Oversight

Review the current technical data sheet and safety data sheet before handling or feeding any water-treatment chemical. Follow all requirements for storage, dilution, personal protective equipment, ventilation, spill response, chemical-feed equipment, and disposal.

Water treatment should be approved by qualified facility, engineering, or water-treatment personnel. Systems involving potable water, food processing, healthcare, power generation, high-pressure boilers, regulated discharge, or critical equipment may have additional requirements.
