Waste water recirculation systems: responsible consumption and green plants Promoting the ecological transition of the manufacturing industry through waste water recirculation systems is one of the objectives of Rösler, a company specialising in the development of mass finishing, shot blasting, and additive manufacturing technologies in combination with industrial cleaning solutions.
W
ater is one of the most important energy sources for the manufacturing industry, as well as a relevant resource in terms of
circular economy. Rösler, one of the world’s leading companies in the design, manufacture, and supply of plant solutions for the treatment of surfaces, is well aware of this. Right from the start, it has decided to complement its standard production with the development of systems for managing and recycling the aqueous solutions used during manufacturing processes. In fact, water is a key component of these operations – but its use inevitably leads to the generation of high volumes of waste water. Focussing on the principles of sustainability and reuse of water, over the years Rösler has developed numerous efficient and reliable systems that recirculate waste water by separating liquids from pollutants, which are then eliminated in the form of sludge. After several years of research, high-speed centrifugal force plants have proved to be the most effective and successful technology. The process consists of separating pollutants and aqueous solutions based on their different densities, by applying a centrifugal force. The aim is obtaining a solution that can be reused in subsequent treatments, thus significantly reducing the consumption of water, chemical additives, and material to be disposed of and, consequently, costs.
Centrifugal technology explained The contaminated liquid to be purified is gathered directly from the processing plants or it is transferred to the centrifuge by a pumping unit (lifting station). The feeding pump continuously transfers the liquid, contaminated with solids or oils, into the centrifuge drum. Rotational speed up to 3,000 rpm ensures that the high-speed centrifugal force generated captures even the smallest and lightest particles and deposits them on the drum’s wall as dense sludge. Other products can be added to support the cleaning process.
