Comparative Study for Organic and Inorganic Draw Solutions in Forward Osmosis
...Show More Authors

The present work aims to study forward osmosis process using different kinds of draw solutions and membranes. Three types of draw solutions (sodium chloride, sodium formate, and sodium acetate) were used in forward osmosis process to evaluate their effectiveness with respect to water flux and reverse salt flux. Experiments conducted in a laboratory-scale forward osmosis (FO) unit in cross flow flat sheet membrane cell.  Three types of membranes (Thin film composite (TFC), Cellulose acetate (CA), and Cellulose triacetate (CTA)) were used to determine the water flux under osmotic pressure as a driving force. The effect of temperature, draw solution concentration, feed and draw solution flow rate, and membrane types, were studied with respect to water flux. The results showed an increase in water flux with increasing feed temperature and draw solution concentrations In addition, the flux increased with increasing feed flow rate while the flux was inversely proportional with the draw solution flow rate. The results showed that reverse osmosis membranes (TFC and CA) are not suitable for using in FO process due to the relatively obtained low water flux when compared with the flux obtained by forward osmosis membrane (CTA). NaCl draw solution gave higher water flux than other draw solutions and at the same time, revealed higher reverse salt flux.

Appearance of the Kurdish press in the Kurdish literature was affected by as set of both external and internal factors. The former was realized in the spreading of press and publications especially at the neighboring countries in the second half of the 19th century. The latter factors, external ones ,were concerned the political situations undergone by the Kurdish people who severely suffered injustice practiced by the Othman authority .All these reasons had driven the educated to migrate to search for more safe places to practice their cultural actions with absolute freedom. Consequently, the first newspaper was issued on 22/4/1898 in Cairo which pointed the birth of the Kurdish press inside and outside Kurdistan region which
