Simona Tanning wins gold
Guangdong, China-based Simona Tanning has been awarded gold status by the Leather Working Group (LWG).
Its new effluent treatment and water recycling plant, which has a 2,400m³ per day capacity, has been in operation since April. The plant is designed to reduce energy consumption and contains state-of-the-art primary equipment as well as anaerobic, facultative and aerobic Biological treatment. The aerobic biological system is operated as a membrane bioreactor (MBR) treatment using submerged membranes. The MBR effluent is further treated with reverse osmosis technology, producing 1,600m³ per day of salt-free, high-quality water, which is used for leather processing. An advanced oxidation process is applied to treat the reverse osmosis concentrate.
