Efficient decolorization and COD removal for the largest landfill in Bali, Indonesia

We were approached by an Indonesian delegation to design and deliver a part of a large government-initiated water treatment system for the largest landfill in Bali, Indonesia. As restrictions become tight to prevent environmental problems in the region, a reliable partner was required.

Based on extensive engineering and design, Mellifiq worked tightly with the local authorities to specify a working solution. Mellifiq delivered a complete oxidation system coupled with prefiltration, integrated pH control and automation to ensure maximum efficiency and COD removal with decolorization. The project was executed in four months from initial discussions to commissioning on-site in Bali.
