Abstract

Summary

The implementation of innovative techniques using cartridge filters and reverse osmosis membranes in this work could be a solution to satisfy increasing water demand.

The feasibility of using membrane in Cheshme khosh desalting Factory was evaluated in the industrial scale study using an reverse osmosis (RO) pilot plant. After a pretreatment in cartridge filters, waste water was introduced to RO unit with a flux of 2000–12000 lit/h. the permeated flux was 600–1500 lit/h with different applied pressures of 5–22 bars. Results showed that COD, BOD, Conductivity, TSS, Color, Turbidity, SO4, Ca.H and SiO2 of waste water were decreased and removed to some extent using RO membranes. The flux of permeated stream and the recovery rate increased with the feed pressure. But the feasible operating conditions for the RO pilot were determined at 15 bar feed pressure with the feed flux of 2600 lit/h witch lead to a permeate flux of 1080 lit/h and 41.54% recovery rate. The zero discharge goal could be achieved using RO system.
