The purification system with total wastewater recovery designed by Ecohouse System keeps the black water from the toilet separate from the grey water from the bathroom and kitchen and from the white water from rainwater, with three separate pipes that respectively reach the Imhoff tank, the Ecobiol purifier and the collection tank.
The Imhoff tank purifies black water with anaerobic bacteria, the Ecobiol purifier purifies grey water with total aerobic oxidation and the collection tank accumulates it together with rainwater.
From the collection tank, the purified water is sent back to the homes via a pump with autoclave and used in the sanitation systems and for the gardens, while the surplus can be used to irrigate vegetable gardens and urban greenery without wasting any of it, therefore with a significant saving on drinking water consumption. Only the water for drinking is needed, which can be made potable by a system dedicated to the outlet of the rainwater tank or drawn from the aqueduct.
The systems are underground with zero environmental impact, do not emit bad odors and produce very little mineralized sludge, to be used on site as a natural fertilizer and use the renewable energy of the photovoltaic system making the systems an economical solution that replaces sewers, leaky or storage tanks and expensive disposal and purification plants.
This is a combined primary treatment tank that allows the physical process of sedimentation and subsequent digestion with anaerobic bacteria in a tank composed of hydraulically communicating sedimentation and digestion compartments superimposed on each other.
Only the sanitary waste is conveyed into the Imhoff tank.
