“…Accordingly, source separation of human urine has been proposed to decrease the load of pharmaceuticals to wastewater plants and the environment (Lamichhane and Babcock, 2012) as well as produce urine-derived fertilizer (Kirchmann and Pettersson, 1995). The basis for urine source separation is that the excreted pharmaceuticals are present at much higher concentrations in undiluted urine than domestic wastewater (Winker et al, 2008a) and thus can be treated more efficiently. Separation of pharmaceuticals from urine would precede nutrient recovery to ensure a pharmaceutical-free fertilizer product.…”

“…It is therefore acceptable to seek separate urine collection, which may significantly decrease the discharge of nutrients into water bodies and prolong the longevity of existing wastewater treatment plants (Wilsenach and Van Loosdrecht, 2004). Besides, the separate treatment of micropollutants contained in urine appears to be an additional merit of the source separation system (Winker et al, 2008).…”

Source-separating urine from other domestic wastewaters promotes a more sustainable municipal wastewater treatment system. This study investigated the feasibility and potential issues of applying a urine source-separation system in tropical urban settings. The results showed that source-separated urine underwent rapid urea-hydrolysis (ureolysis) at temperatures between 34-40 o C, stale/fresh urine ratios greater than 40%, and/or with slight fecal cross-contamination. Undiluted (or low-diluted) urine favored ureolysis; this can be monitored by measuring conductivity as a reliable and efficient indicator. The optimized parameters demonstrated that an effective urine source-separation system is achievable in tropical urban areas. On the other hand, the initial release of CO 2 and NH 3 led to an elevated pressure in the headspace of the collection reservoir, which then dropped to a negative value, primarily due to oxygen depletion by the microbial activity in the gradually alkalized urine. Another potential odor source during the ureolysis process was derived from the high production of volatile fatty acids (VFA), which were mainly acetic, propanoic, and butyric acids. Health concerns related to odor issues might limit the application of source separation systems in urban areas; it is therefore vital to systematically monitor and control the odor emissions from a source separation system. As such, an enhanced ureolysis process can attenuate the odor emissions.Implications: Urine source separation is promising to improve the management of domestic wastewater in a more sustainable way. The work demonstrates the achievability of an effective urine source-separation system in tropical urban areas. The installation of urine-stabilization tanks beneath high-rise buildings lowers the risk of pipe clogging. Conductivity measurement can be utilized as a reliable process indicator for an automated system. However, urine hydrolysis raises a strong potential of odor emission (both inorganic and organic), which might limit the application of source separation systems in urban areas. An enhanced ureolysis process could shorten and attenuate the odor emissions.

“…Pharmaceutical toxics are released into the water system, from many point and nonpoint sources. There is also a growing concern about the level of excreted pharmaceutical compounds from wastewater systems that may end up in the water supply (concentrations are usually \1 lg/L) as a parent compound or metabolite, and thus adversely affecting the human health and the environment (Behera et al 2011;Daughton and Ternes 1999;Winker et al 2008). Ibuprofen (C 13 H 18 O 2 ), also known as a-methyl-4-(2-methylpropyl)-benzene acetic acid, is an antipyretic product and has been classified as a non-steroidal anti-inflammatory drug (NSAID).…”

Pharmaceuticals have gained significant attention in recent years due to the environmental risks posed by their versatile application and occurrence in the natural aquatic environment. The transportation and distribution of pharmaceuticals in the environmental media mainly depends on their sorption behavior in soils, sediment-water systems and waste water treatment plants, which varies widely across pharmaceuticals. Sorption of ibuprofen, a non-steroidal anti-inflammatory drug, onto various soil minerals, viz., kaolinite, montmorillonite, goethite, and activated carbon, as a function of pH (3-11), ionic strength (NaCl concentration: 0.001-0.5 M), and the humic acid concentration (0-1,000 mg/L) was investigated through batch experiments. Experimental results showed that the sorption of ibuprofen onto all sorbents was highest at pH 3, with highest sorption capacity for activated carbon (28.5 mg/g). Among the minerals, montmorillonite sorbed more ibuprofen than kaolinite and goethite, with sorption capacity increasing in the order goethite (2.2 mg/g) \ kaolinite (3
