-
Primary Settling Cell: In this initial phase, wastewater is stored, allowing sedimentation to occur naturally. Solids settle at the bottom, while the clearer water moves on to the next stage.
-
Secondary Advanced Filter Cell: This cell features layers of pebbles and stones of varying sizes, arranged to act as a natural filter. Wastewater passes through these layers, undergoing filtration. Baffles within the chamber guide the water through the cell, enhancing the filtration process.
-
Tertiary Biological Wetland Cell (TBWC): The heart of the system, this cell comprises layers of gravel, stones, and mud, planted with wetland species like Elephant Grass (Pennisetum purpurem), Cattails (Typha Spp.), Reeds (Phragmites Spp.), Cannas Spp., and Yellow Flag Iris (Iris pseudoporous). These plants, commonly found in natural wetlands, possess filtration and treatment capabilities. Additionally, ornamental and flowering plants such as Golden Dhuranda, Bamboo, Nerium, and Celosia can be incorporated for both aesthetic and functional purposes.
-
The treatment process leverages the biological, physical, and chemical actions of these plants. Oxygen is transferred from the atmosphere through the plants to the root zone, where particles of effluent are absorbed by the roots as nutrients. This creates an aerobic reaction, complemented by anaerobic processes, naturally treating the wastewater. The processed water, collected after passing through various baffles, is suitable for non-potable uses like municipal gardens, fountains, and irrigation.
-
Low-Cost Technology: This natural treatment method is cost-effective, producing negligible sludge and requiring a small footprint. It can be customized in various dimensions based on land availability.
-
No Maintenance Technology: Utilizing specific wetland plants for filtration and oxygen supply, the system needs only periodic pruning, making it virtually maintenance-free.
-
Odor and Insect-Free: The system's hydraulics are maintained below the gravel surface and operate on gravity, eliminating odors and preventing insect breeding. Additionally, it requires no power, making it highly efficient and eco-friendly.
-
Simple Construction: The system is straightforward to construct, requiring no specialized skills.
-
Water Reuse: The treated water can be reused for irrigation and flushing purposes, with minimal losses of just 2-3%.
-
ROOTZONE TECHNOLOGY: A SUSTAINABLE SOLUTION FOR WASTEWATER TREATMENT
RootZone Technology, also known as Constructed Wetland Technology, is a groundbreaking, self-sustainable method for wastewater treatment that mimics the natural processes of a wetland. This complex ecosystem functions as a nutrient sink and remover, effectively treating wastewater from small houses, residential societies, hotels, commercial complexes, municipal sewage, and pretreated industrial effluent.
