<\/p>\nThe aim of Sacmi\u2019s new technology for the recovery and treatment of wastewater is to drastically reduce water consumption and, at the same time, entirely recycle it, together with the solid precipitate found in it, to be fed back into the production process. The innovative system was launched on the market a few months ago and the first plant has now been successfully installed and started up at Ceramica Flaminia at its headquarters in Civita Castellana.<\/p>\n
<\/p>\n
How does it work? It is a two-stage process. First the wastewater is pre-treated to obtain a primary sedimentation. Next, a membrane ultrafiltration system comes into operation using crossflow filtration which, thanks to the specially designed filtering membranes, does not require the chemical additives normally used in solid-liquid separation and decanting processes.<\/p>\n
The result is that the recovered water \u2013in the case of Flaminia more than 90% in volume of the 5,000 m3 treated\u2013 can be reused for a variety of purposes in the sanitaryware production process (such as, for example, mould washing during the high-pressure casting process or in the glazing lines). In the same way, the recovered solid precipitate \u2013in the past considered waste to be disposed of\u2013 can also be directly reused in the ceramic body and thus completely recycled.<\/p>\n
The solution is Sacmi patented \u2013due to the crossflow ultrafiltration process being specifically applied to ceramic waste recycling\u2013 and is characterized by its modular set-up. In fact, after an initial running-in period for the new plant, Ceramica Flaminia plans to expand its capacity to meet the entire factory requirements through wastewater recovery and treatment.<\/p>\n
From Sacmi\u2019s point of view, the solution is a breakthrough heralding a new approach to industrial water consumption. In fact, the new system can lead to an estimated saving in the consumption of freshwater of more than 70%. Furthermore, the possibility to fully recycle the solid precipitate, transforming it from waste product to resource for reuse in the production process, is a valuable opportunity for achievement of a circular economy.<\/p>\n","protected":false},"excerpt":{"rendered":"
