Verfahren zur weitestgehenden Aufbereitung von Süßwasser, Brackwasser, Meerwasser und Abwasser zu Trink- und Brauchwasserzwecken

摘要

The treatment of raw water, particularly the desalination of waste or other water with a high salt content, is accomplished by means of a process which includes two membrane separation steps performed in concentrate sequence. The concentrate from the second membrane separation step is further treated by means of a thermal concentrating procedure. The water to be processed is first treated to minimize the formation of scale during the first membrane separation step and the concentrate from the first membrane separation step is similarly treated. The overall process also includes the production of materials necessary for reconditioning ion exchange apparatus employed for raw water conditioning and concentrate treatment.
