Due to increasing demand, climate change and pollution, it is becoming increasingly challenging to meet all needs in the provision of clean drinking water. This also applies to companies, which means that water reuse is playing an increasingly important role.
RWB Water recently realized two Rinsing Water Recovery Units (STUs) for a project with Brabant Water in Tilburg and Loosbroek. These STUs play an important role in purifying rinse water from sand filters, which is usually contaminated with oxidized iron and manganese.
Sand filters are essential in purifying drinking water, but they require frequent flushing, resulting in the production of contaminated rinse water. Rinse water can be reused through the use of STUs. STUs clean rinse water by filtration using ceramic membranes. Purification with ceramic membranes has the following advantages, among others:
– Minimization of the amount of waste water to be discharged to more than 95%
– Low chemical consumption
– Low Total Cost of Ownership
– Robust and sustainable technology
Ultimately, the filtered water can be returned to the drinking water process because of its good quality.
In addition to this project, RWB Water has also realized a similar installation for other customers. Examples of these customers are:
– Vitens, flushing water reuse installation of 50 m3/h
– Grolsch, rinse water reuse installation with a recovery of 95%
