DISCHARGE POINT LOCATION Wastewater from Nhon Trach 3 IP Module 2 will use the existing (Module 1) – discharge network. Therefore the location of Module 2 discharge 2 will be unchanged WASTEWATER TREATMENT TECHNOLOGY Treatment efficiency of the treatment plant (Module 1) is very effective. The results from eelier treatment can be seen in Table 26 and 27 as below, while the up-to-date results 05/ 2012) were already presented in table 4: 26:The characteristics of the IP centralized wastewater treatment (Phase 2 - Module 1), September 2011 QCVN WW characteristics 9/2011 Pre-treatment No Parameters Unit After Column B with Treatment Kq=1.1;Kf=1.0 pH - 6.2 7.2 5.5 - 9.0 mg Undetected COD 760 165 O2/L (LOD=10) mg BOD5 330 9 55 O2/L TSS mg/L 148 48 110 Colour Pt-Co 42 13 165 Undetected N-NH4+ mg/L 25.8 11 (LOD=0.056) TN mg/L 27.3 4.8 44 TP mg/L 9.4 1.72 6.6 Undetected CN- mg/L 0.013 0.11 (LOD=0.005) Undetected Undetected Cr6+ mg/L 0.11 (LOD=0.01) (LOD=0.01) Undetected Undetected Cr3+ mg/L 1.1 (LOD=0.025) (LOD=0.025) Undetected Fe mg/L 1.37 5.5 (LOD=0.06) Zn mg/L 0.19 0.21 3.3 Undetected Cu mg/L 0.18 2.2 (LOD=0.1) Undetected Undetected As mg/L 2.2 (LOD=0.001) (LOD=0.1) Undetected Hg mg/L 0.003 0.011 (LOD=0.001)
