From Filthy Filters to Clean Water: Boiler System Cleaned and Protected by Aquaguard 810 in Only 6 Weeks
At a glance
Poor water quality and lack of treatment in this process water boiler system meant regular shutdowns and cleaning were required. Aquaguard 810 and process improvements were introduced. The result: clean water, reduced maintenance cost, corrosion protection and no more costly shutdowns and cleaning.

FROM FILTHY TO CLEAN
Challenges
A 200,000 L system with five gas fired hot water heating boilers operated several years without treatment, increasing risk for severe corrosion damage. Regular blow down and fresh water addition failed to prevent costly shutdowns and cleaning. Pressure gauges and filters regularly plugged with corrosion by-products and debris.
Solutions
System assessment was completed and Aquaguard 810, an all-organic boiler treatment, was introduced. Equipment improvements included addition of a two gallon pot feeder, pressure gauge replacement, and installation of a relief valve in the filter housing.
Results
Clean Water and Clean System
After only 6 weeks of treatment, boiler water and filters were clean and clear.
Protected from Corrosion
Aquaguard 810 removed corrosion by-products from system, replacing them with a protective chemical film to protect the system from future corrosion. Iron levels in water dropped from 3.3 ppm to 0.19 ppm.
No More Shutdowns or System Pre-Cleaners
System pre-cleaners and shutdowns were eliminated, reducing system maintenance costs and enhancing reliability.
Data
AQUAGUARD 810Â is an all organic treatment composed of corrosion and scale inhibitors, dispersants and buffering agents for use in closed loop systems. Â It does not suffer from issues regarding waste discharge (heavy metal) or biological control (nutrient for bacteria), unlike molybdate and nitrite based treatments.
