Industrial effluents

Tanneries

Tanneries belong to industrial sectors with the highest levels of water consumption. To make good quality leather from one ton of raw material, experience has shown that up to 60 m³ of water are required. The volume of waste water, which contains high levels of alkaline and organic substances, is, of course, correspondingly high. Direct discharge or treatment in municipal waste water clarification plants is therefore not possible. For corresponding waste water treatment in tanneries, GEA decanter centrifuges are used which optimally prepare a subsequent biological treatment.

GEA and Pulmuone honor generations of cold noodle craftsmanship

When plant-forward South Korean food producer Pulmuone brought GEA the challenge of developing a modern spin on the traditional chewy cold (naengmyeon) noodle, GEA’s R&D experts were up to the challenge. They helped develop what is now a commercial hit produced with less water and electricity than previously existing methods. The result is also true to the traditional origins of the dish as well as Pulmuone’s health, well-being and sustainability roots.
