In the middle of June 2018 the C-MEM MBR plant in Rocktenn Monterrey subsidiary, which is owned by one of the leading Mexican paper and cardboard packaging producers, was started up.

The plant (2 modules, 128 cartridges) with downstreams reverse osmosis treats 173 m³/d wastewater from paper and cardboard production. First, the wastewater is treated biologically with the C-MEM ultrafiltration technology and then cleaned to recycling quality by the downstreams RO, which reduces the water consumption drastically, as the paper and cardboard production process requires relatively much water.
