Alvim vs. NCH vs. Solenis vs. Nalco: Comparing Biofilm and Microbial Activity Sensors
Most water treatment programs still find out about biofilm the same way: heat transfer drops, a filter clogs, or someone finally swabs a coupon and sends it to a lab. By then the biofilm is already established and a shock dose is the only way out. The sensors on the market today claim to catch […]
Why Food and Beverage CIP Cycles Need Biofilm Monitoring, Not Just Flow and Temperature Logs
CIP validation records show time, temperature, and flow. They do not show whether the surfaces are actually clean. Biofilm that survives a standard CIP cycle can do so undetected — until it affects product quality or a hygiene audit finds it.
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. […]
