Ash depth filters were developed which can simultaneously remove nitrogen, phosphorus and bacteria from human waste streams while simultaneously maintaining a flow rate which is acceptable for domestic use processing urine from one individual for 1 month if the filter bed has a volume of approximately 3 l. Nitrogen and phosphorus depletion is achieved by the formation of Struvite Enriched Ash, which can subsequently be used as a slow-release garden fertilizer. Depth filtration and sanitation by high pH removed all detectable bacteria from this home-based system. doi: 10.2166/washdev.2020.013 om http://iwaponline.com/washdev/article-pdf/10/2/374/713144/washdev0100374.pdf er 2021 Michael Witty (corresponding author) Raja Al-Bahou Sarah Copley Math and Science, Florida SouthWestern State College, Fort Myers, FL, USA E-mail: [email protected] Nin N.
