Products for installations that are cleaned or treated by recirculation: food process circuits and industrial water circuits. On one side, chlorinated alkaline detergents, non-foaming for recirculation or foaming for open surfaces, and acid descalers and anti-scale products. On the other, disinfectants: a food-grade product, bactericidal or virucidal depending on the dose, and a biocide for legionella control in industrial water, with start-up and maintenance doses.
