Today, February 14, 2016, Dr. Urine research team has published a paper entitled "Control of Urine Odor in Different Sanitation Practices and Its Implication on Water Saving."
To avoid odor in sanitation systems, urine is usually diluted or flushed with water, which leads to high water consumption. However, in the case of water saving toilets, the smell may remain in sanitation systems if the systems are not well managed or if the urine is flushed with insufficient amounts of water. But how can we recognize the smell? And how is it possible to control it?
For managing anything, first, it should be characterized well. In the case of smell also, we have standard methods to quantify the smell via Threshold Odor Number (TON) measurements.
In this study, the relationship between characteristics of flushing water (amount of it, pH, etc.) and TON of the diluted urine is investigated. It is proved that in order to remove odor, washing or flushing with a high amount of water is not necessarily required. Instead, lower water consumption can be utilized by modifying the characteristics of the flushing water.
Shouldn’t this be considered as a step ahead toward achieving SDGs, especially in developing countries? What a Valentine’s Day gift from Dr. Urine to SDG6!
