Pre-Bleed Lockout and Lockout Period: Why These Two Controller Features Matter for Cooling Tower Treatment Accuracy
Cooling tower water treatment controllers are most commonly evaluated on what they can control — conductivity setpoints, biocide dosing schedules, pH management. What is less often discussed is what they prevent: the accidental delivery of chemicals under conditions where those chemicals will not work, or worse, will cause damage. Two features in the Aquarius Ultima […]
Why Biofilm in a Cooling Tower Is a Fundamentally Different Problem Than Planktonic Bacteria
When cooling tower water treatment programmes fail to control Legionella or other microbial threats, the instinct is usually to dose more biocide. Sometimes this works. Often it does not — because the real problem is not the concentration of bacteria in the water. It is the bacteria that are not in the water at all. […]
