Organic fouling in the forward osmosis process is complex and influenced by different parameters in the forward osmosis such as type of feed and draw solution, operating conditions, and type of membrane. In this article, we reviewed organic fouling in the forward osmosis by focusing on wastewater treatment applications. Model organic foulants used in the forward osmosis literature were highlighted, which were followed by the characteristics of organic foulants when real wastewater was used as feed solution. The various physical and chemical cleaning protocols for the organic fouled membrane are also discussed. The study also highlighted the effective pre-treatment strategies that are effective in reducing the impact of organic fouling on the forward osmosis (FO) membrane. The efficiency of cleaning methods for the removal of organic fouling in the FO process was investigated, including recommendations on future cleaning technologies such as Ultraviolet and Ultrasound. Generally, a combination of physical and chemical cleaning is the best for restoring the water flux in the FO process.

“…Hu, Wang, Ngo, Sun, and Yang (2018) reported that membrane fouling was readily controlled in anaerobic dynamic membrane bioreactors (AnDMBRs) along with other potential advantages such as low capital and operating (energy) costs, and increased biogas production. Dutta and Nath (2018) used sodium sulfate decahydrate, (Glauber salt or Na 2 SO 4 •10H 2 O) as a solute in the forward osmosis (FO) process to treat brackish water and textile wastewater. The FO process was successful in the dewatering of both wastewaters.…”

“…25 RO/NF recentna istraživanja obrade tekstilne otpadne vode i uklanjanje bojila iz njih ukazuju na izraženo blokiranje i stvaranje "kolača" na NF i RO membranama. [26][27][28][29] Posljedice blokiranja membrana su smanjenje radnog vijeka membrane, niža kvaliteta P40 permeata i povećanje operativnih troškova. 30 U svrhu smanjenja navedenih problema u radu s RO/NF membranama poželjan korak predobrade je membranski postupak ultrafiltracije.…”

Otpadne vode tekstilne industrije pripadaju kategoriji najjače onečišćenih industrijskih otpadnih voda te su posebna opasnost za vodeni okoliš. Cilj ovog istraživanja bio je ispitati membransku učinkovitost zadržavanja bojila iz tekstilne otpadne vode (TOV) s komercijalnim ultrafiltracijskim (UF) membranama (GH, GK, PT, PU, PW, MW) širokog područja graničnih molekulskih masa (MWCO), od 2 do 50 kDa. Testirane UF membrane rezultirale su smanjenjem obojenja i intenziteta obojenja od 56,35 % do 97,93 %. Membrane nižih MWCO vrijednosti (ispod 3 kDa) mogu se smatrati prikladnim za uklanjanje bojila iz realnog uzorka TOV-a.
