Samsung’s Hwaseong CampusSustainable water management has been at the core of Samsung’s environmental efforts for more than a decade. The company’s extensive water management practices largely focus on the 3R’s ― reduce, reuse, recycle. In order to minimize its water footprint, Samsung consistently optimizes its manufacturing processes and equipment. The company also utilizes water filtration technology ― known as the ‘membrane process’ ― to increase its water recycling rate by treating wastewater and reusing it in utility facilities.
Electro-deionization systems remove contaminants through eco-friendly, chemical-free processes
Concentrated water generated during ultrapure water production can also be reused in utility facilitiesJust last year, these efforts enabled Samsung to conserve several hundred million gallons of water at the Hwaseong campus alone. Whereas between 2017 and 2018, the site consumed an average of 13.24 billion gallons of water per year, in 2019, consumption levels dropped to 12.97 billion gallons. This translates to approximately 274.7 million gallons of annual water savings, which is enough water to accommodate approximately 200,000 people in Korea for an entire month. Samsung also employs a team of dedicated water experts who ensures that its water treatment technologies remain green. As a result, instead of chemical treatment options, the company utilizes eco-friendly processes, such as electro-deionization, and energy-saving equipment to produce the ultrapure water needed to manufacture semiconductors at the nanoscale. Never content to rest on its laurels, Samsung has pledged to continue to pursue sustainability at its semiconductor sites, and will seek to minimize its environmental footprint at every opportunity.
The wastewater from semiconductor production is treated at the Green Center and discharged into local streams
