The processing of the vinhau00c7a from the ethanol with CO2 sequestration chemical atmosfu00c9rico and simultaneous production of nutrient solutions.

摘要

The treatment process of the vinhau00c7a from the ethanol (Arie) by using one step precipitation with solution of hydrated lime to raise pH buffering and training of COrrectivo organo mineral that has sedimentau00c7u00c3o by layers. The supernatant is a nutritive solution is clarified, biodegradable, with low content of solids in suspension, turvau00c7u00c3o and phosphorus.This nutrient solution is stable under the air over time.When exposed to the atmosphere, the pH decreases to close to neutrality by reaction of CO2 atmosfu00c9rico with alkalinity, precipitating in the form of calcium carbonate and magnesium.At the same time, during the stage of exposure to air, there is the removal of ammonia, either by volatilizau00c7u00c3o or by reaction with air for the training of nitrogen compounds that precipitate.
