Using MgO for Alkaline Dehydration of Human Urine Collected in Source-Separated Sanitation Systems
We recently published a new paper on the use of Magnesium Oxide as an alkaline substrate for dehydrating urine in the journal Frontiers in Environmental Science. https://www.frontiersin.org/articles/10.3389/fenvs.2020.619901/full Abstract: Fresh human urine, after it is alkalized to prevent the enzymatic hydrolysis of urea, can be dehydrated to reduce its volume and to produce a solid fertilizer.… Continue reading Using MgO for Alkaline Dehydration of Human Urine Collected in Source-Separated Sanitation Systems
