Abstract:

It is a great challenge for effective treatment of shale gas produced water (SGPW), a typical industrial wastewater with complex composition. Single forward osmosis (FO) or membrane distillation (MD) process has been widely used for desalination of SGPW, with membrane fouling not well addressed. Fertilizer draw solution (DS) with high osmotic pressure is less likely to cause FO fouling and can be used for irrigation. An integrated process using fertilizer-driven FO (FDFO) and MD process was proposed for the first time for SGPW treatment, and characteristics of fertilizer DS and powdered activated carbon (PAC) enhancement were assessed. The DS using KCl and (NH4)(2)SO4 had high MD fluxes (36.8-38.8 L/(m(2)& sdot;h)) and low permeate conductivity (below 50 mu S/cm), increasing the contact angle of the MD membrane by 113 % than that without FO, while the DS using MgCl2 2 and NH(4)H(2)PO(4 )produced a lower reverse salt flux (0.9-3.2 g/(m2 & sdot;h)). 2 & sdot; h)). When diluted DS was treated using PAC, the MD permeate conductivity was further reduced to 35 mu S/cm without ammonia, and the membrane hydrophobicity was maintained to 71-83 % of the original. The mechanism of the FDFO-MD integrated process for mitigating MD fouling and improving permeate quality was analyzed, providing guidance for efficient SGPW treatment.
