Ultrafiltration as tertiary treatment for municipal wastewater reuse

Water reuse is an enduring topic that benefits the society and future generations of mankind. Ultrafiltration (UF) one most cost-effective treatment technologies for improving water quality. In this study, a semi-industrial UF pilot plant with periodical classic backwash (CB) air (AB) was operated automatically to evaluate its feasibility sustainability municipal wastewater find out optimized filtration condition. This study carried 15 conditions investigate impacts flux (J in L·h−1·m−2), cycle time (t min), frequency (BW) on membrane hydraulic performance fouling management. Through comparative analysis all quality, permeability variation, irreversible management, recovery rates, sustainable J80t40BW1/3 (flux 80 L·h−1·m−2, 40 min, 1 AB followed 3 CBs), J60t60BW1/4 60 4 J60t60BW1/3 stood from others higher overall performances. Additionally, showed excellent reversibility control, which around 1.25–2 times CB average. After all, long term operation condition winter summer confirmed system could provide adaptable regardless temperature feed The permeate quality good enough be reused non-potable applications as it met guidelines World Health Organization, standards France recent EU regulation agricultural irrigation. work confirms great interest tertiary gives operational indications industrial-scale production reclaimed water.
