Solution
​
Our solution has a high degree of innovation, as it works with modular systems of natural sewage treatment with the capacity to serve from a residence to an entire city.
​
We use biomass and proprietary processes to remove organic and inorganic pollutants from sewage. In short: we transform sewage into water!
In up to 6 hours, sewage is treated and returned to nature in the form of class C2 water (equivalent to rivers and rain).
​
Efficiency and sustainability in the same process
-
Bar Screens to separate inorganic materials
-
The sewage passes through bamboo culms, already covered by a blend of bacteria. They work by degrading chemically complex organic matter into simpler compounds such as carbon dioxide, methane and ions. This conversion is carried out by essentially anaerobic pathways, although aerobic bacteria may occur in small amounts, mainly in the first chamber.
-
The degradation of organic matter continues in a similar way in the next three chambers, increasing the efficiency of the process.
-
Function to stabilize effluent elements and bacteria from stages 1 and 2. Removes BOD* and COD** through filtration and natural aeration due to the filtering mesh.
-
Its main function is the final filtration and polishing of the effluent. The effluent from the third stage no longer has any sediment.
Efficiency of Zero Esgoto's sewage treatment plant
​
Since it's fully modular, cheaper, does not lead to any residual sludge, does not use chemicals or electricity, Zero Esgoto's sewage treatment plants have lots of advantages in comparison with our competition.
