Ultrafiltration combined with ozone for domestic laundry wastewater reclamation and reuse

摘要

Ozone was incorporated into an ultrafltration system to produce higher quality reclaimed water from domestic laundry wastewater. Characteristics of the wastewater for nitial washing waste were 488～2,847 mg/L COD, 62～674 mg/L MBAS, and 38～857 mg/L SS. The wastewater was contacted with ozone in a 10L storage tank and circulated through the membrane module for inner pressurized cross-flow filtration.
