The dizzer 5000 plus modules feature a 50m² membrane surface area. The job of the modules from inge watertechnologies is to pretreat the seawater to prepare it for reverse osmosis. The treated water is required for the steel production process. The UF facility is also used to treat the ‘blowdown water’ from the steel works’ cooling towers.

Ralf Krüger, the sales manager responsible for this project at inge watertechnologies said: “The mixture of seawater and process water in the treatment facility makes this project particularly challenging. Approximately 10% of the feedwater comes from the production process. The specific requirements stipulated for this facility included achieving SDI values below two – even though the raw water often has an SDI value in excess of 15. Fortunately the technology we supply is capable of reliably ensuring that kind of performance over the long term.”
