New Ultrafiltration Module Rack

Ultrafiltration systems are now used all over the world to treat many different types of water – including drinking water, waste water and industrial process water – and are increasingly also being employed as a means of pretreating seawater for reverse osmosis. With such a broad variety of potential applications, ultrafiltration systems must have the ability to adapt to myriad different requirements, especially with regard to their configuration and footprint. While sea water treatment plants are often built in desert regions where there is normally plenty of space for the facility, conventional drinking water treatment plants designed to recycle water for industrial use are frequently confined to much smaller spaces. Typically, these plants are only willing to modernise their facilities on condition that no major building work or structural alterations are required. The footprint of the rack system is therefore a major criteria in this decision-making process.

The “T-Rack” system from inge watertechnologies AG (Germany) is already regarded as a hydrodynamic solution that makes optimum use of the available space when installing UF modules, but the developers have now made some key changes that have made the system even better.

The feed and drain pipes are integrated in the end caps of the headers, the filtrate connections are welded to the module bodies and headers, there are no O-rings and all the flanges of the header pipes are mounted in the same plane.

The modules can be arranged in either two or four rows and each row can be operated as a separate filtration line. This concept offers unparalleled flexibility and helps keep investment and operating costs to a minimum.
