Field Shower Wastewater Recycling System: Development of a Program of Instruction and Preliminary Analysis of Its Potential Health Implications

摘要

This report discusses the development of a suggested program of instruction for operators of a Field Shower Wastewater Recycling System (FSWRS)--a system designed to recycle water used in showers in the field. A 40-hour training course will be sufficient to properly train a Bath Specialist in FSWRS operations. These operations will emphasize water treatment procedures and water sampling and testing. Analysis of field needs indicated that water quality testing can be limited to measurements of pH, turbidity, and residual chlorine and that these measurements can be made with relatively unsophisticated equipment. It was found that most constituents of shower wastewater that could pose health hazards will be removed during FSWRS recycling operations. However, basic procedures should be followed, such as avoiding ingestion of recycled shower waters and ensuring that FSWRS operators take appropriate precautions in handling sulfuric acid and untreated waters. Although no health hazards are anticipated to result from components such as soaps and shampoos, there is concern about the hazard potential of volatile organic compounds, heavy metals, chlorinated compounds, and chlorination byproducts. The most likely anticipated health effects would be dermal or eye irritations. Keywords: Water reclamation; Water analysis; Water chemistry; Water conservation; Water filters; Water treatment.
