dizzer® modules of inge AG are technologically and economically the best choice

Greifenberg, 04 April 2007 – In the world water development report of UNESCO in 2003, Belgium has been the red lantern bearer with regards to water quality. Today, strict regulations administer the use of water and also the rates for water and waste water have increased. Looking for a long-term secure and cost efficient technology, two projects have now been awarded to the German company inge AG .

Comprehensive tests have been carried out in order to check the stability of the ultrafiltration membranes and to prove its reliability when dealing with the worst feed water qualities. Ralf Krueger, International Sales Manager of inge AG, summarizes the test results as follows: “Our dizzer® modules had to resist even the hardest water conditions, but on the other hand, this actually gives us a chance to show unique strengths of our extremely stable Multibore® membrane.” inge AG, a German technology leader in the field of drinking water, process water and waste water treatment, has therefore been awarded two projects in which its dizzer® modules will be implemented.

In the first plant water that has previously been used for the washing of vegetables is treated. Depending on the kind of vegetable, the water is polluted at very varying levels. After a biological pre-treatment, the water is immediately fed into the UF system. The varying pollution level of the water therefore reflects a large challenge for the stability of the membrane. The same applies for the second water treatment plant which provides process water for industrial companies. The water is taken from the river Gent which quality also varies depending on the season and on the amount of industrial pollution fed into the river.

Due to the relatively bad feed water quality, the membrane must be backwashed very frequently in order to clean the filter pores effectively. The intense pollution and the high frequency of the backwash stress the fibres enormously. Fibre breakages might occur – a risk that the operator cannot afford. The fact that even under high loads the Multibore® membrane did not show any fibre breakage has been one of the key decision criteria. In addition to the reliability and safety of the technology also cost efficiency plays a major role. The in-out filtration method implemented by inge offers the end user significant cost advantages.

This makes the use of this technology not only secure but in addition also very efficient. Both water treatment plants are planned to be commissioned in the first half of this year.



inge AG at a glance

The internationally active inge AG has its headquarters located in Greifenberg near Munich, Germany. The company manufactures and sells ultrafiltration membranes and modules for the treatment of drinking water, process water and waste water. It is the largest ultrafiltration corporation for water treatment in Germany and currently employs 50 people. In order to meet the increasing demand of the Asian markets, inge AG also maintains a sales office in China. Compared to conventional water treatment methods, use of the ultrafiltration technology of inge AG offers numerous advantages: the modules can be easily and quickly installed in the system, the membrane fibres are extremely robust and stable. Since inge started its operations six years ago, it has not seen any fibre breakage case of its membranes. Such exceptional advantages ensure low operation costs of systems and thus lower investment costs from a long-term point of view. An additional important advantage is the security that it can provide for health: the small-pore sized filters of the patented Multibore® membrane which is developed by inge AG reliably reject particles, micro-organisms, bacteria and viruses out of the water, thus securing germ-free and clean drinking water.
