The breakthrough electrocatalytic urban planting solution, “EC Flow System”,  upcycles planting wastewater into nutrient-rich irrigating water for different types of urban plants. Through patented electrocatalytic technology, the nutrient-rich irrigating water upcycled by EC Flow System achieves nitrogen cycle restoration, which improves chlorophyII and leaf nitrogen content to secure greener and healthier plants, hence improving the lifetime and significantly reducing the needs of urban planting replacement and maintenance.
