Source Separation of Human Urine - Separation Efficiency and Effects on Water Emissions, Crop Yield, Energy Usage and Reliability
Urine is the waste fraction from households which contains the largest amounts of nutrients. In Sweden it contains approximately 70% of the nitrogen and 50% of the phosphorous and potassium in all household waste and wastewater fractions. During the 1990-ies, urine separation has been thoroughly investigated in waterborne systems in Sweden. Measurements have shown that between 50% and 85% of th...

متن کاملField Utilization of Dried Water Hyacinth for Phosphorous Recovery from Source-Separated Human Urine
This research demonstrated the feasibility of converting source-separated human urine into a solid fertilizer by means of continuous absorption and solar thermal evaporation using dried water hyacinth as adsorbent. In a preliminary experiment, the dried petioles of water hyacinth (DWH) absorbed urine in a mean rate of 18.78 ml·g within 7 d, retrieving about 3.46% urine dissolved solids (UDS). I...

متن کاملFate of major compounds in source-separated urine.
Urine separation is a promising alternative to present-day waste water management. It can help to manage our nutrient flows in a sustainable way. Currently, techniques are being developed to recycle and treat source-separated urine. These techniques, however, must consider the spontaneous processes that change the separated urine. The initial cause of changes is the contamination with microorga...
