Faecal Sludge Management: Systems Approach for Implementation and Operation
TL;DR: Faecal Sludge Management: Systems Approach for Implementation and Operation as mentioned in this paper addresses the organization of the entire faecal sludge management service chain from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge.

The behaviour of pharmaceuticals and heavy metals during struvite precipitation in urine
TL;DR: Phosphate recovery from urine over struvite precipitation is shown to render a product free from most organic micropollutants and containing only a fraction of the already low amounts of heavy metals in urine.

Struvite precipitation thermodynamics in source-separated urine.
TL;DR: Struvite precipitation eliminates phosphate efficiently from urine, a small but highly concentrated stream in the total flux of domestic wastewater, and a conditional solubility product K(s)(cond)=[Mg(aq)].[NH(4)(+)+NH(3)].[P(ortho)]=10(-7.57)M(3) was derived to calculate struvitesolubility in urine at 25 degrees C.

Struvite precipitation from urine - Influencing factors on particle size.
TL;DR: Struvite formation in a CSTR (continuously stirred tank reactor) process was shown to be a reliable stable process that does not require any pH control and a method based on conductivity measurement is presented to estimate ionic strength, which is needed for equilibrium calculations.

TL;DR: This paper reviews the characteristics of waste streams and the potential treatment processes and technologies that can be adopted and applied in urban slums in a sustainable way and recognition of the potential of anaerobic co-digestion for treatment of excreta and organic solid waste for energy recovery as an alternative to composting.
