Therefore a good biological control of a water system is essential. Biocides should have a good performance in water systems and a very low environmental impact when discharged.

Ferrocid^® 4601 is a newly developed and fast reacting Biocide of our R&D department. It is a single component, stabilized, oxidizing source of Bromine. The new product yields to improved results in alkaline cooling systems especially compared to Sodium Hypopchlorite. Ferrocid^® 4601 is free of Chlorine and has a wide range of application.

Ferrocid^® 4601 inhibits the microbiological growth and eliminates existing micro-organisms, like bacteria, fungi, and algae. It is also active in the control of Legionella pneumophila bacteria, which causes Legionnaire's disease (Legionellosis). Ferrocid^® 4601 gives very good results in systems with high risk of process contamination.

Compared to conventional treatment for alkaline cooling systems (Sodium Bromide with Chlorine gas resp. Bleach) there is no need for an expensive mixing station (including two dosing pumps) but just a single dosing pump. The monitoring can easily be done by Halogen sensors.
