Use of Somatic Coliphages in Biosensoring of Hygiene Safety of Recycled Wastewater

Outflows from secondary stages of conventional mechanical-biological wastewater treatment plants (WWTPs) still contain significant concentrations faecal pollution indicators suggesting the potential presence pathogenic organisms. The decrease in concentration somatic coliphages and bacterial during technological (coagulation, sand filtration, membrane ultrafiltration, sorption on granular activated carbon, disinfection, accumulation) a semi-operational plant designed for multi-stage tertiary or rather recycling treated was monitored discussed. During treatment, bacteria were better removed than coliphages, hence inclusion among water quality control reuse is entirely appropriate. Subsequent including essential safe water.
