A Practical Guide for Building a Simple Pit Latrine

This technical do-it-yourself guide provides step-by-step instruction on building simple pit latrines. It was designed for use at the individual household level to assist families in West Africa who have already decided to build their own latrines.The dialogue in the guide should be enacted by a facilitation team in the form of a skit followed by a debate. Each key step (placing the latrine, digging the pit, making the slab, building the superstructure) should be represented and followed by a discussion with the public, with responses and comments being provided for each step.

Struvite Production from Source Separated Urine in Nepal

This thesis explores the potential reuse of struvite effluent in Siddhipur Nepal. The hypotheses being investigated are that preliminary struvite precipitation prevents clogging during drip fertigation with urine and that drip-fertigation with urine is superior to bucket spreading, because the ammonia volatilization is strongly reduced.

Optimization of Coagulation-Flocculation Process with Aluminium Sulfate Based on Surface Methodology

A coagulation-flocculation process, based on aluminium sulfate, is studied in this paper using Response Surface Methodology, in order to establish the optimum parameters to achieve a maximum suspensions removal. This methodology allows a treatment plant operator to determine easily, after a small number of trials, the optimum conditions to achieve maximum suspensions removal efficiency.
