Pretreatment & Filtration Systems

The risks of untreated or poorly pretreated water

Every drop of water entering your systems carries impurities that can damage equipment, reduce efficiency, and create compliance risks. Without effective pretreatment, operators are left scrambling to fix costly problems instead of preventing them.

Request a Consult

Scale & deposits

Dissolved solids and salts cause scaling and corrosion, reducing efficiency and damaging boilers, towers, and medical devices.

Microbiological Contamination

Untreated water promotes bacterial growth and biofilm, which accelerate corrosion and increase health risks like Legionella.

Variable Water Quality

Tap water quality fluctuates daily by source and region, introducing inconsistent contaminants that impact performance and compliance.

Compliance Risks

Failure to meet standards like AAMI ST108, ASHRAE 188, or industry-specific requirements can lead to failed audits, reputational damage, and operational downtime.

Pretreatment & Filtration FAQs

View All FAQs

Frequently asked questions

What is water pretreatment and why is it important?

Water pretreatment removes impurities such as minerals, salts, and contaminants before the water enters boilers, cooling towers, or closed loops. Proper pretreatment prevents scaling, corrosion, and fouling, improving system efficiency and extending equipment life.

What types of pretreatment equipment are used in water treatment?

Common pretreatment equipment includes water softeners, reverse osmosis (RO) systems, deionization (DI) units, carbon filters, and microfiltration systems. These technologies prepare make-up water for reliable performance in industrial and commercial systems.

How does pretreatment improve boiler and cooling tower efficiency?

Pretreatment reduces hardness and dissolved solids in feedwater, which minimizes scaling, corrosion, and blowdown frequency. This lowers energy and water use, reduces maintenance costs, and increases uptime for boilers and cooling towers.

What problems can occur without proper water pretreatment?

Without pretreatment, facilities often face scale buildup, corrosion, shortened equipment life, higher energy costs, and compliance issues. Inconsistent feedwater quality can also cause downtime and unplanned repairs.

How is pretreatment water quality monitored?

Pretreatment systems are monitored through routine testing of pH, conductivity, hardness, and dissolved solids. Many facilities also use automated controllers and remote monitoring for real-time visibility and audit-ready reporting.

Are there sustainable or “green” pretreatment options available?

Yes. Facilities can reduce chemical use and improve safety with plant-based inhibitors, onsite oxidant generation, and efficiency programs that minimize water and energy waste while maintaining system performance.
