The GENKS Water Purification System is a fully autonomous solution that transforms polluted water bodies into thriving, self-sustaining ecosystems. Designed for governments and private managers of lakes, reservoirs, and aquaculture farms, it combines solar-powered robotics, eco-friendly purification agents, and AI to deliver continuous restoration, improving key indicators like harmful algae levels by over 70%. Unlike conventional methods that rely on toxic chemicals or heavy machinery, GENKS operates with 60% greater treatment efficiency by using natural photocatalytic materials derived from discarded shellfish. An intelligent Digital Twin models the ecosystem in real time and guides this treatment with surgical precision. The result is not just cleaner water, but the full revival of biodiversity, achieved without dredging or sludge removal. By eliminating this heavy work, GENKS slashes long-term costs to just $0.8 per ton, a fraction of the $2 to $3 per ton typical of traditional approaches, making clean water accessible for all.
