Boiler water treatment prevents corrosion, scaling and carryover — three issues that cause unplanned downtime and efficiency losses in power and manufacturing plants.
Proper boiler water chemistry extends tube life, improves steam purity and reduces fuel consumption. This guide covers the core treatment chemicals and how they work together in an integrated program.

Core Boiler Treatment Chemicals
Oxygen scavengers remove dissolved oxygen that causes pitting corrosion in boiler tubes and feedwater lines. Sodium sulfite, hydrazine and sodium metabisulfite are common scavengers selected based on system pressure and regulatory requirements.
Alkalinity builders and pH adjusters maintain feedwater pH in the optimal range (typically 10.5–11.5) to minimize acid corrosion. Caustic soda and phosphate programs are widely used in low- and medium-pressure boilers.
Scale inhibitors and sludge conditioners prevent calcium and silica deposition on heat transfer surfaces. Phosphate-based programs precipitate hardness as mobile sludge rather than hard scale.
An integrated boiler chemical program from Drashti Chemicals includes regular water analysis, dosing recommendations and compliance documentation for plant engineers and utility managers.
Monitoring and Best Practices
Test feedwater and boiler water daily for pH, alkalinity, dissolved oxygen and conductivity. Maintain a logbook to track trends and adjust chemical dosing before problems develop.
Pre-treatment of make-up water (softening, deaeration, RO) reduces chemical demand and improves overall program efficiency. Coordinate boiler chemicals with your pre-treatment vendor.
Drashti Chemicals supplies boiler treatment chemicals from Vadodara with COA, MSDS and technical support for power plants, textile mills and manufacturing facilities across India.

Frequently Asked Questions
Why are oxygen scavengers essential in boiler water treatment?
Dissolved oxygen causes pitting corrosion in boiler tubes. Oxygen scavengers remove residual oxygen from feedwater, extending asset life and preventing costly tube failures.
What pH should boiler feedwater maintain?
Most low- and medium-pressure boilers maintain feedwater pH between 10.5 and 11.5 using caustic soda or phosphate alkalinity programs to minimize acid corrosion.
How often should boiler water be tested?
Daily testing of pH, alkalinity, dissolved oxygen and conductivity is recommended. Drashti Chemicals can advise on test frequency based on your boiler pressure and make-up water quality.
Do you supply complete boiler chemical programs?
Yes. Drashti Chemicals supplies oxygen scavengers, phosphates, caustic soda and sludge conditioners with scheduled deliveries and water analysis support.
Can you supply boiler chemicals outside Gujarat?
Yes. Pan-India delivery for bulk boiler treatment programs. Export documentation available for international buyers.
