Treatment of Wastewater Using Reverse Osmosis for Irrigation Purposes
الملخص
This work investigates the performance of reverse osmosis (RO) for the reclamation
of treated sewage effluent (TSE) to be used as irrigation water for food crops. The
feed water used in this study was a real sample of ultra-filtered tertiary treated sewage
effluent (TSE). Reverse osmosis (RO) was evaluated using the following experimental
conditions applied pressure (10 - 20) bar, flow rate 3.5 LPM and (BW30LE) membrane.
The performance of RO was evaluated according to the water flux and rejection of
dissolved solids. The final water quality was compared with irrigation water standards.
The results reported in this study show that reverse osmosis (RO) is capable of
reclaiming treated sewage effluent (TSE) to be used as irrigation water for food crops.
The maximum average flux was 77.7 LMH achieved using a feed pressure of 16 bar. The
permeate water generated using RO had high quality which met the irrigation standards
for food crops.
