Why biofilm resists chlorine — and why raising the dose does not help
Surface-attached biofilm bacteria are 150 to 3,000 times more resistant to hypochlorous acid than free cells. We explain why increasing the dose is not the answer, using data from the peer-reviewed literature.

On-site generation or bulk chemicals? An operating decision
The difference between producing disinfectant on site and buying it ready-made; a comparative evaluation in terms of safety, operating cost, continuity and efficacy.

How is Legionella risk controlled in water lines?
Why does Legionella grow in hot-water lines and cooling towers, what is its relationship with biofilm, and how is it controlled with continuous disinfection? A technical explanation.
-
What is that pool 'chlorine smell' actually a sign of?
The sharp chlorine smell and eye irritation in indoor pools is a sign not of too much chlorine but of combined chlorine (chloramines). The cause, and the on-site solution.

Anolyte and catholyte: the two outputs of a diaphragm cell
A diaphragm electrolysis cell turns salt, water and electricity into two solutions: a hypochlorous acid anolyte for disinfection and a caustic catholyte.

How does electrochemical activation (ECA) work?
How does ECA technology produce disinfectant from salt, water and electricity? The working principle of the electrolysis cell, the solutions produced, and the advantages of on-site generation.

What is hypochlorous acid, and why is it more effective than chlorine?
What is hypochlorous acid (HOCl), how does it differ from sodium hypochlorite and chlorine gas, and why does it disinfect more strongly at the same chlorine level? A technical explanation.
