Cooling Tower Chemistry That Doesn't Answer to Your Vendor

A cooling tower advisory engagement can encompass a wide range of services depending on your situation. Core capabilities include:

• Program Audits — full chemistry, equipment, and operational review including physical cooling tower assessment, open heat exchanger investigation, feed equipment inspection, vendor report review, and sampling protocol evaluation
• Chemistry Optimization — saturation index modeling, cycles-of-concentration strategy, inhibitor selection, and dosing validation using first-principles analysis
• Historical Analysis — review of years of water chemistry, operational, and service data to identify trends, events, and root causes
• Failure Analysis — engineering investigation of scale, corrosion, fouling, or biological events including root cause determination and prevention recommendations
• Site Conditions & Risk Identification — onsite assessment of physical setup, equipment condition, and site-specific risk factors
• Full Engineering Reports — comprehensive written reports covering findings, risk matrix, optimization opportunities, and prioritized recommendations
• Contract & Vendor Oversight — review and negotiation support for water treatment service agreements and performance benchmarking
• Expert Witness — technical testimony and reports in disputes involving cooling tower chemistry, equipment failure, and water treatment program performance

All engagements are tailored to your specific system, goals, and situation — and delivered as fixed-scope, fixed-fee projects.

Even the best water treatment service providers are focused on their scope of service. Independent advisory adds a layer of senior expertise that works alongside your existing team — not against it. The value is typically realized quickly: operational savings from chemistry optimization, reduced downtime from proactive risk identification, and stronger contract terms often return the advisory investment within days to weeks of implementation — not months. Many clients also find that independent review improves the working relationship with their service provider by establishing clearer expectations and shared performance metrics.

Most cooling tower programs use the Langelier Saturation Index (LSI) to predict scale risk — but LSI only looks at calcium carbonate in isolation. Competing ion saturation modeling, developed and enhanced by IWA professionals, evaluates all dissolved minerals in your water simultaneously to identify which ones are actually at risk of depositing under your specific operating conditions. This reveals risks — silica, calcium sulfate, calcium-magnesium silicates — that traditional monitoring methods were never designed to detect, and were historically not monitored at all. It also prevents overreaction to apparent LSI values that, once modeled properly, represent no real deposition risk. The result is a clearer, more accurate picture of your actual program risks and the right treatment response.

Industrial Water Advisory serves refineries and petrochemical facilities, power generation (fossil, nuclear, and renewable thermal), data centers, district cooling systems, large commercial HVAC, and pharmaceutical and food manufacturing. While remote advisory is available for clients worldwide, most engagements benefit from at least one onsite visit — and we travel globally for them. We have deep, long-term customer experience across North America, South America, and the Middle East, and have worked in virtually every major industrial region of the world.

A program audit engagement follows a structured process:

1. Discovery Call — an initial conversation to understand your system, operating conditions, current program, and audit objectives
2. Request for Information — we request 3 years of water analysis and application data, chemical product information, control parameters and setpoint history, service reports, current program documentation, and critical heat exchanger information for each application
3. Initial Review — desktop chemistry modeling, data trend analysis, and identification of preliminary areas of focus before the site visit
4. Onsite Assessment — a minimum of 2 days onsite per application to physically review the cooling tower condition, open heat exchanger status, feed equipment installation and performance, chemical storage and handling, instrumentation, and operational setup. Discussions with your operators, engineers, and current service provider are an integral part of this phase
5. Full Engineering Report — a comprehensive written report covering risk identification, optimization opportunities, contract gap analysis, failure analysis determination where applicable, and prioritized recommendations with supporting data

All engagements are fixed-scope and fixed-fee, agreed before work begins.
