The inge watertechnologies system uses ultrafine membranes pores to filter 1,600 m³ of water an hour to remove viruses, bacteria and suspended solids from Trier’s water supplies.

The project, which starts in the spring of 2012, will mean that 38,400 m³ of water from the Riveris reservoir will be purified each day through a purely physical method, without the use of chemicals. It follows a long-term pilot project during which the polyethersulphone (PES) membrane supplied by inge watertechnologies AG proved to be better than conventional polyvinylidene fluoride (PVDF) products in treating Trier’s reservoir water. Another benefit was the pH compatibility of the PES membrane, which avoids the need for frequent use of chlorine-containing cleaning chemicals.

The system used is inge’s T-Rack vario ultra-compact rack system, which incorporates 312 dizzer XL 0.9 MB 60 modules in six filtration lines. The core component of these modules is the patented Multibore membrane and they are designed to have operating pressures that are three or four times lower than conventional solutions and no need for air scouring.
