Case Studies
What a properly engineered boiler, cooling tower or RO treatment program is designed to achieve — illustrated through representative scenarios built from typical industrial water chemistry challenges.
Challenge
A textile processing unit running a medium-pressure fire-tube boiler on hard, high-alkalinity makeup water was seeing visible scale buildup on tubes within a few months, along with rising fuel bills and a manual descaling routine every shutdown.
Program
A threshold scale inhibitor and oxygen-scavenger dosing program was designed around the feed-water hardness and alkalinity profile, with weekly TDS and sulphite residual checks to keep dosing on target.
Directional Outcome
Boilers in this condition typically move out of the 7–10% fuel-loss-per-mm-of-scale range described in our water-cost data within one to two dosing cycles, with tubes staying visibly clean between annual shutdowns.
Challenge
An automotive component plant's cooling tower was showing reduced heat-exchanger efficiency and biofilm growth in the fill pack, raising both energy cost and Legionella compliance risk during warmer months.
Program
An integrated corrosion-inhibitor, biocide and bio-dispersant program was set around the cycles of concentration and metallurgy, with monthly biological monitoring added to the AMC schedule.
Directional Outcome
Towers with comparable fouling typically recover a meaningful share of the up-to-40% heat-transfer efficiency loss biofilm causes, while bringing biological counts back within a compliance-ready range.
Challenge
A food and beverage facility's RO plant was fouling within weeks of each membrane change, driven by elevated silica in the feed water — cutting recovery and pushing membrane life well under the expected 5–7 years.
Program
A high-performance polymer antiscalant formulated for elevated silica was dosed at the feed line, paired with a scheduled CIP cleaning cycle to restore flux between services.
Directional Outcome
Systems with this fouling pattern typically see membrane service life trend back toward the 5–7 year range once antiscalant dosing is matched correctly to feed-water silica levels.
