Abstract
Slanted soil system is low cost, simple system suitable for greywater treatment. Performance of the slanted soil system for greywater was evaluated in light of required water quality for irrigation reuse. Removal rate of COD and BDOC, those may cause clogging of irrigation facility, was 52–83% and 88–89%, respectively. LAS, one of the major surfactants, was removed more than 80%. Phytotoxic test showed that more than 2.82 m treatment is required. Only fine soil (1–4 mm) performed 5 log10 and 3 log10 reductions of Escherichia coli and MS2 phage, while coarse soil could not remove those pathogens. Clogging was observed in fine soil after 3–5 weeks operation; however, combination of coarse soil chamber and fine soil chamber could extend it to 8 weeks, without decrease of treatment performance. Reductions of total COD and LAS were described by first-order reaction model, and reaction coefficient k was described by equation of per area discharged rate.
