Demineralized Water Production

Since 2019, WHAUP invested to upgrade its current water reclamation process to produce demineralized water. The process is equipped with a membrane and ionic exchanged technology to further remove mineral components from reclaimed water. Demineralized water is utilized by industries, such as power plants, petrochemicals and electronics industries that aim to prevent machinery and equipment erosion from chlorine. Such demineralized water production process was implemented at WHA Eastern Industrial Estate (WHA EIE), which generated 55,000,000 Baht of revenue. In addition to adding value to WHAUP’s current products, this innovation also helped reduce up to 1.5 Mm³ per year of water withdrawal from natural sources. In 2020, WHAUP increased the demineralized water production’s capacity by 1.6 Mm³ , making the total current demineralized water production capacity of the Company to be 3.1 Mm³ .
