บทคัดย่อ (EN): Waste water generated during the processing of natural rubber latex into Ribbed Smoked Sheets (RSS) contains substantial amount of organic compounds, leading to environmental pollution when disposed untreated. An integrated waste water treatment system (IWWTS) was designed, installed and evaluated in an RSS group processing centre (GPC). The IWWTS was evaluated initially for three years during the experimental period and for another one year during the actual operational period at the RSS processing centre, by analyzing samples collected from various points of treatment with respect to the pollution parameters. Field evaluation of this system installed in two more GPCs were also was carried out. The IWWTS could achieve removal efficiency in BOD 99%, COD 99%, TS 87% and DS 85%. The pH increased from 5.9 in the untreated effluent to 7 in the treated water. As a means of aerobic digestion by passing the waste through the plant root zone, a reed bed system with Chrysopogon zizanioides (Vetiver) was also tried. All the pollution parameters pollution in the treated final water were within the safe limits for discharge in to the environment. “Zero liquid discharge’’ was achieved in RSS processing by recycling the treated waste water. The HRMR yielded 8 m3 biogas/day. The biogas was used as fuel for burning in the smoke house to generate heat for sheet drying with a saving of 35 % in firewood use.
