چکیده مقاله
Recent progress in reverse osmosis RO technology isn't limited to RO membrane materials, module designs and RO process optimization It involves prior feed treatment which directly impacts RO system performance the continuing challenges of membrane fouling in RO membranes may be addressed by increasing the operational e ciency through the employment of correct pretreatment options which may mitigate organic and inorganic fouling by selectively rejecting contaminants before reaching the RO unit Highly polluted water resources have put critical stress on the prevailing conventional pretreatment techniques, whereby membrane pretreatment has emerged as a promising alternative This paper provides an summary of the eventand current trends in conventional and non conventional RO pretreatment techniques whereby the techniques are critically reviewed to tell readers of potential improvements in such areas This paper addresses the foremost drawbacks of conventional pretreatment methods which havenecessitated the utilization of membrane pretreatment techniques
