PDF FACTATI ODS FACULTATIVE PONDS - snapp.icra.cat 90% BOD and TSS; high pathogen reduction and relatively high removal of ammonia and phosphorus; Total HRT: 20 to 60 days, Low capital costs where land prices are low; very low operation costs. Based on operational simplicity, low cost and high removal efficiencies (99% BOD5, suspended solids and coliform bacteria removal), AIWPS is highly recommended for up to 1000 mg/L BOD5 concentration. 0000003742 00000 n

Waste Stabilization Pond Systems are summarized and Advanced Integrated Wastewater Pond Systems (AIWPS) are investigated. The technical content was reviewed by Prof. Duncan Mara (University of Leeds, England). They are designed for BOD removal and can treat water in the BOD range of 100 to 400 kg/ha/day corresponding to 10 to 40 g/m2/day at temperatures above 20C (MARA and PEARSON, 1998). u"d u={7}Y"0X@/1` >#*J9:$x.W[9s!96$Yp3hb30%$'~jVu+ =ZM
