Pressure -Ultrafiltration
Feed Trans Membrane Pressure
Figure 13. Differential pressures at UF, washes were performed when differential is 20 PSI,
cleaning procedures include 2% weight citric acid, 0.1% weight sodium hypochlorite, 1% special
RO cleaning weight, sodium hydroxide at pH 10.5 and 0.5% weight sodium metabisulfite

Turbidity -Ultrafiltration
Feed Filtrated
Figure 14. Turbidity in feed was typically less than 18 NTU and occasionally with values above
60 NTU, which did not affect the operation, the turbidity of the filtrate was typically less than
2.1 NTU suitable for the RO process
